Au Gratin: A baked or grilled dish sprinkled with grated cheese or bread crumbs or both. Baba: Rich, fermented sponge introduced in France by King Stanislaus Leczinski of Poland out of his admiration for the fairy tale, Ali Baba and the Forty Thieves, from which the name is derived. It was popularized in Paris by the Polish Chef Stotchore at Rue Montgueli, Julienne; he added raisins to the recipe. Béchamel: The mother sauce, created by Louis de Béchamel, Marquis de Nointel, maitre d hotel to Louis XIV ( ) Bacon: Boned pork, usually the side or belly meat; may be smoked or uncooked and cured with salt, sugar and spices.

7 Introduction to Bakery and Confectionary Most of bakers products are made of the ingredients such as flour, sugar eggs, milk, stabilizers and leaveners. There are two departments in a bakery, namely the bake section & the pastry section. The Pastry Section Although pastry section is part of the kitchen and, under the supervision of the head chef or catering manager, it is considered to be a separate unit in a catering establishment. The main reasons for this are that specialist staff and equipment are required for it to work efficiently and to avoid contamination of sweet goods by the savory smells and flavors of the foods being prepared/stored in the kitchen and larder areas. The purpose of the pastry section is to prepare and serve all hot and cold sweet dishes, pastries, cakes, gateaux, petits fours, ice-cream dishes, confectionery and yeast goods. Often this includes breads and special customer requirements such as celebration cakes. The section has specialist facilities, equipment and staff, and will therefore liaise with the kitchen and larder sections on the production of savoury items; for example, pie coverings, vol-au-vents, sausage rolls, choux paste, cheese straws,andpastasfleuron. Pastes and other items will be supplied by the pastry section. In some cases they will be prepared and baked by them for completion and service in the main kitchen. Depending on the type of establishment, the section would provide food for lunch, dinner and supper menus, afternoon teas, buffets, banquets and possibly outdoor catering functions. If stewed fruits, croissants and brioche rolls are served at breakfast, these would also be prepared by the pastry section. Basic Principles and Ingredients of Bakery Basic Principles: Most bakers products are made of the same few ingredients - flour, shortening agent, sugar, eggs, water or milk, and leavening agent. You should have no difficulty in understanding the importance of accuracy in bakery, since slight variations in proportions or procedures can mean great differences in the final product. Formula: In case of cookery, the ratio of ingredients is called recipe. But here we call it a formula, since the proportion of mix has to be accurate.

8 Measurement in the Metric system: There has always been confusion with the usage of measure; the U.S. System is not much in use in our Indian Bakeries and confectioneries. We use the metric system. In the metric system, there is one basic unit for each type of measurement. gram is the basic unit of weight litre is the basic unit of volume meter is the basic unit of length celsius is the basic unit of temperature. Baking process: The changes undergone by a dough or batter as it bakes are basically the same in all baked products, from bread to cookies. You should know how these changes occur so that you learn to control them. Dough formation Wheat contains proteins called the glutenin and gliadin, which together form gluten, when wheat flour is moistened and mixed. Gluten also is a protein. When wheat flour is mixed with water and kneaded, it forms a sticky and elastic mass called the dough. Gluten is responsible for both the stickiness and the elasticity of the dough. At the time of grinding the grain into flour, gluten quality can be improved by the addition of small quantity of certain substances known as improvers.

9 Gas Formation and leavening Leavening is the production or incorporation of gases into a baked product to increase volume and to produce shape and texture. These gases must be retained in the product until the structure is set. The gases primarily responsible for leavening baked goods are (i) carbon dioxide, which is released by the action of yeast, baking powder and baking soda, (ii) air, which is incorporated into dough and batters during mixing and (iii) steam or hot dry air, which is formed during baking. Acquiring the gases As the gases are formed, they expand and are trapped in a stretchable network formed by the proteins in the dough. The proteins are primarily gluten and, sometimes egg protein. Without gluten or egg protein, most of the gases would escape, and the product would be poorly leavened. Breads without enough gluten are heavy. Gelatinization The starches absorb moisture, expand, and become firmer. This contributes to structure. It begins to gelatinize (i.e., to form a soft some what elastic product like a fruit pulp) at about 65 0 C. Coagulation Like all proteins, gluten and egg proteins coagulate or solidify (i.e., the particles in the proteins gather together into a solid mass), when they reach high enough temperatures. This process gives most of the structure to baked goods. Coagulation begins at about 74 0 C. Correct baking temperature is very important. If it is too high, coagulation will start soon, even before the expansion of gases has reached its peak. The resulting product will have poor volume or a split crust. If the temperature is too low, the proteins will not coagulate soon enough, and the product may collapse. Evaporation This takes place throughout the baking process. If a baked product of a specific weight is required, allowances must be made for moisture loss when scaling the dough. e.g., a loaf of 400 gram of baked bread shall need about 500 gram of dough. Shortening All fats are shortening agents. Films of fat get in between the layers of gluten in the flour and shorten or break the gluten thereby making the dough tender and flaky. On cooking, different shortening agents release trapped gases at different temperatures. The product when consumed melts in the mouth; e.g., biscuits. Proper shortening agent should be selected for each product. Browning A crust is formed as water evaporates from the surface and leaves it dry. Browning occurs when sugar caramelizes and, starch and sugar undergo certain chemical changes caused by heat. This contributes to flavour. Milk, sugar and egg increase browning.

10 Staling Staling is the change in texture and aroma of baked goods due to a change of structure and a loss of moisture by the starch granules. Stale baked goods have lost their fresh baked aroma and are firmer, drier, and more crumbly than fresh products. Prevention of staling is major concern of the baker, because most baked goods loose quality rapidly. Staling begins almost as soon as the backed items are taken from the oven. There are apparently two factors for staling. The first is loss of moisture or drying. This is apparent, for example, when slices of fresh bread are left exposed to air. The bread becomes dry. The second factor is a chemical change in the starch structure. Bread should never be stored in a refrigerator; either it should be stored at room temperature for a short period or frozen for a long term storage.

11 Unit-2 Bakery Layout Baking Ingredients The usual ingredients in Bakery are as follows: Wheat flour Starches Sugars Syrups Fats

12 Shortenings Margarine Oil Lard Milk and cream Cheese Eggs Leavening Agents Nuts and fruits Chocolate and Cocoa Salt and spices Wheat Flour Wheat Flour is the most important ingredient in Bakery. It provides bulk and structure to most of the bakers products, including breads, cakes, cookies and pastries Types of Wheat: The characteristics of flour depend on the variety of wheat from which it is milled, the location in which the wheat is grown, and the growing conditions. Types of wheat used are: Hard Red Spring Hard Red Winter Soft Red Winter Durum White Hard Wheat flour is used in the making of breads Soft Wheat flour is used in the making of cakes and pastry. Straight Flour: Straight flour is 100% extraction as flour. In other words, it is made from the entire wheat kernel after the bran and germ are removed. It is a product of Hard Wheat; it has high protein content and is usually used for making breads.

13 Whole - wheat Flour: It is made by grinding the entire wheat kernel, including the bran and germ. The germ, as you have learned is high in fat, which can become rancid. Self - rising Flour: It is a white flour to which baking powder and sometimes salt have been added. The advantage is that the baking powder is blended in very uniformly. Soft Wheat Flour: Let us consider the Cake flour. The cake flour is weak or has low gluten; it is made from soft wheat. Pastry flour is used for pie dough and for some cookies, biscuits and muffins. Rye four: Next to white and whole wheat, rye is the most popular flour for bread making. Although rye flour contains some proteins, it does not form gluten. Therefore breads made with 100% rye flour will be heavy and dense. Starches In addition to flours, other starch products primarily to thicken puddings, pie fillings, dessert production are as follows. are also used in Bakery. Unlike flour, they are used and similar products. The most important starches in Corn Starch: It has a special property that makes it valuable for certain purposes. Products thickened with corn starch set up almost like gelatin when cooled. For this reason, it is used to thicken cream pies and other products that must hold their shape. Waxy Maize: It has valuable properties. Because they do not breakdown when frozen, they are used for products that are to be frozen. Also, they are very clear when cooked and give a brilliant, clear appearance to fruit pie fillings. Waxy maize does not set up firm like corn starch, but makes a soft paste, which has the same consistency in hot or cold condition. This is not suitable for cream pie fillings.

14 Instant Starches: The instant starches are available precooked or pre - gelatinized; so they thicken cold liquids without further cooking. They are useful in situations where heat will damage the flavour of the product, as in fresh fruit glazes, like strawberry. Sugar: Sugar occurs naturally in nearly all plant structures - fruits, leaves and stems; however sugar for general commercial use is obtained from two major sources, sugarcane and sugar beet. 60% of the world's supply of sugar is obtained from sugar cane and 40% from sugar beet. Cane contains approximately 18% sugar, while, beet contains approximately 15% sugar. Classification: Source - Beet and Cane Country - West Indies, Guyana, England, India. Catering uses - Specific types of sugar should be purchased for particular purposes. E.g.: Cube sugar would usually be purchased for table use to serve with tea and coffee; icing sugar would usually be purchased for dusting or royal icing. Chemical group Monosaccharide and Disaccharides Functions: To sweeten, cakes, pastries, sweet drinks etc. To act as preservative. To soften the gluten in flour and to make the baked product more tender to eat and lighter in texture. To colour the cooked product. e.g., the addition of sugar will assist bread and cakes having a good colour. Action of Heat on Sugar: Soft ball. Making of marzipan and fondant Hard ball. Making nougats, petit fours etc.

15 138 - Soft crack. Making Italian Meringue Pulled sugar. Making 01 baskets, ribbons, roses, bows, etc Hard crack Caramel. Making for cream caramel. Sugars or sweetening agents have the following purposes in baking: To increase keeping qualities by retaining moisture. To give crust colour. To act as creaming agents with fats and as foaming agents. To tenderize and impart fineness of texture, partly by weakening the gluten structure. To make any dish sweeter and flavoured. Types of Sugars: Granulated Sugar: Very fine and ultra fine sugars are finer than regular granulated sugar. They are prized for making cakes ad cookies, because they make a more uniform batter and can support higher quantities of fat. Sanding Sugars: These are coarser and are used for coating cookies, cakes, and other products. Coarse sugar, can be used in syrups, where its mixing properties are not a factor. Even a very coarse sugar will dissolve readily when boiled in water. Invert Sugar: When a sucrose solution is heated with an acid, cane sugar (sucrose) breaks down in to equal parts of two simple sugars, glucose and fructose. A judicious mixture of glucose and fructose is called invert sugar. Invert sugar has two properties that make it interesting to the baker. It holds moisture well and thereby helps to keep cakes fresh and moist. It resists crystallization Invert Sugar is produced commercially, and it is also present in honey. Dehydrated Fondant:

16 It is a soft creamy preparation of sugar, water, and glucose that is used as a basis for candies or icings. Recipe: Brown Sugar: Brown sugar is mostly sucrose (80 90%). It also contains varying amounts of caramel, molasses, and other impurities, which give it its characteristic flavour. In a nut shell, brown sugar is a regular cane sugar that has not been completely refined. Keep brown sugar in an air tight container to prevent it from drying out and hardening. Syrups: Molasses: It is concentrated sugar cane juice. It contains large amounts of sucrose and other sugars, including invert sugar. It also contains acids, moisture, and other constituents that give it its flavour and colour. Darker grades are stronger in flavour and contain less sugar than lighter grades. Molasses retains moisture in baked goods and therefore prolongs freshnes Malt Syrup: Malt is available in two forms. Dried malt extract is simply malt syrup that has been dried. It must be kept in an air tight container to keep it from absorbing moisture from the air. Malt flour is the dried, ground, malted (softened by steeping in water and allowed to germinate) barley that has not had the malt extracted from it. It is obviously a much less concentrated form of malt. Leavening Agent: Yeast: Yeast is the leavening agent in breads, dinner rolls, Danish pastries, and similar products. Yeast causes fermentation of sugar into carbon dioxide gas and alcohol. This release of gas produces the leavening action in yeast products. The alcohol evaporates completely during and immediately after baking. Fermentable sugar in bread dough comes from two sources. It is added to the dough It is produced from flour by enzymes that breakdown the wheat starch into sugar. These enzymes are present in the flour and are added in the form of malt.

17 Yeast is a microscopic plant that accomplishes this fermentation process by producing enzymes. Some of the enzymes change complex sugar (sucrose and maltose) into simple sugars (glucose and fructose). Others change the simple sugars into carbon dioxide gas and alcohol. Yeast is a living organism; it is sensitive to temperatures as shown below: At 1 0 C Yeast is inactive 15 0 C 20 0 C Yeast has slow action 20 0 C 32 0 C Best for growth of yeast 38 0 C Yeast reacts 60 0 C Yeast dies Yeast is available in two forms - compressed and active dry. Let us now study regarding two chemicals used in bakery for releasing carbon dioxide. Baking Soda: Baking soda is the chemical, sodium bicarbonate. If moisture and an acid are present, baking soda releases carbon dioxide gas, which leavens the product. Heat is not necessary for the reaction. Baking powder: Baking powders are mixtures of baking soda plus an acid to react with it. They also contain starch, which prevents lumping and brings the leavening power down to a standard level. The baking powder requires only moisture to be able to release gas. Like baking soda, baking powder can be used, only if the product is to be baked immediately after mixing. Salt: It brings out the flavor of other ingredients. The other name of salt is Sodium chloride. It is readily available in all part of the world. In solid ( rock salt) in solution ( sea salt). Correct quantity of salt can transform a normal dish into wonderful dish. It should be used skillfully, or too much of it may spoil the dish. Salt is available in 3 forms: 1) Table salt ( Fine) 2) Coarse or freezing salt 3) Celery salt which is a blend of celery root. It is used for flavoring certain dishes as an alternate to fresh celery or celery seed.

18 Uses of Salt 1) Use of correct amount of salt improves the flavor of the savoury dishes & when little is added it enhance the flavor 2) It has a physical effect on gluten of flour (strengthen gluten and its resistance). 3) Cauliflower when put in salted water makes the insects out. 4). it has a controlling effect on activity of yeast in bakery. It controls fermentation. 5) Salt added to water to make green vegetables help colour retention & enhance taste. 6) Salting is one of the oldest popular methods of preserving. 7) Salt is essential for good health. Fats: There are many different varieties of fats available in the market. These fats have varying properties that make them suitable for different purposes. While selecting a fat for a specific use, a baker must consider the following properties; its melting point, it softness or hardness at different temperatures, its flavour and its ability to form emulsions. Earlier, under baking process, we mentioned regarding the ability of a fat to act as a shortening agent; films of fat get in between the layers of gluten in the flour and shorten or break the gluten thereby making the dough tender and flaky. We generally use the word shortening to mean any of a group of solid fats, usually white and tasteless, that have been especially formulated for baking. Shortenings may be made from vegetables oils (hydrogenated) and animal fats. There are two main types: Regular shortenings Emulsified shortenings. Butter Any fresh butter consists of about 80% fat, 15% water and about 5% milk solids. Butter is available salted and unsalted. Unsalted butter is more perishable, it is hard when cold, very soft at room temperature and it melts easily. Butter is having high flavour when compared to the shortenings. Butter also has the melting qualities. Margarine: It is a butter substitute, cheaper than butter and less in cholesterol content. The flavour in margarine is less than that of Butter. It contains 80-85% fat, 10-15% moisture and 5% salt and milk solid. Usually this is made out of vegetable fat. Sometimes, animal fat is also used. Oil: It is liquid fat and used less for shortening. The main use of oil in the bakeshop is for greasing, deep frying, and as a wash for some kinds of Rolls.

19 Lard: Lard is the rendered fat of pigs. Because of its plastic quality, it was once highly valued for making flaky pie crusts. Since the development of modern shortenings, however, it is not often used in the bakeshop. Shortening: These are the fats which shorten the gluten surround them and make them more easily broken (short). When added to bread it gives a bit tenderness, richness & a sheen to crumb. For the selection of good fat following points should be considered. A frying fat should have more smoking point, low moisture content, high stability & acceptable flavor. Fats & oils having high percentage of unsaturated fats has more shortening power than saturated fats. Animal fat such as butter, lard & suet make food short, i.e. break off ( short) & readily melt in the mouth. For the selection of shortening the following factors should be observed: 1) Shortening should cream well or it will affect the cake volume. 2) It should have no moisture then it will be short 3) The shortening should be stable & should not get rancid so that the cooked product has a good keeping quality. 4) The right consistency of fat, i.e. solidified puff & flaky pastry, soft for cakes & biscuits help to get good texture. To acquire good results in baking because of fats & other ingredients, certain rules should be followed Fats & oils are used for various purposes: - 1) Spread 2) Shortenings 3) Tempering] 4) Salad Dressing 5) Frying Medium Egg Certain foods play a major role in cooking. One of them is egg. It can be served as a main dish or as an accompaniment to other dishes or as an ingredient in another item. Due to its versatility, the egg is considered a primary ingredient in culinary preparation, providing moisture, structure and richness in dishes. It is also an emulsifier and aerator, when properly handled and used. In cooking, the term egg refers to the oval, thin-shelled ovum of a bird, used as food. There are many types of eggs, such as those of goose, duck and turkey.

20 Composition Let us study the composition of egg Composition of an Egg The shell or outer covering of the egg may be white or brown. Shell color has no relation to the quality, working properties or the nutritive value of the egg. The colour of the shell is determined by the breed of the chicken. Composed primarily of calcium carbonate, the shell is very fragile. It is porous, which allows it to breathe. The porous nature of the shell allows loss of moisture, even if unbroken. The white part is the food and the moisture source for the embryo in a fertilized egg; it accounts for 67% of liquid weight of the egg. Egg white is made up of two parts: a thick white liquid and a thinner liquid part. Albumin, a protein, is the major component of the white. This protein also contains sulphur. Albumin, in the egg white, is valued by the cook and baker for its ability to hold air, when beaten. Besides, egg white provides light fluffy texture for souffls, chiffon pies, angel food cakes and other food items. The yolk is the unfertilized embryo in the egg and is yellow in colour. The depth of colour will vary with the feed of the hen. The yolk is high in fat and protein and contains iron. The yolk is valued for the richness and texture, which it provides in both cooking and baking. Primarily, an egg is graded by weight: Grade A around 70 grams Grade B around 60 grams Grade C around 50 grams Purchasing Factors Purchase only the quantity of eggs needed for one or, at most, two weeks; accept only eggs which are clean, sound and odour free. There are various methods of preserving eggs, such as oiling, wrapping and refrigeration. However, the preferred method is refrigeration. Exposure to temperatures above15 degree C shortens the life of an egg. Higher temperatures often break down an egg white and yolk. Fresh eggs should be properly boxed. The best packaging for the commercial kitchen is fiberboard boxes. Eggs should be packed in the carton in snug fitting trays to reduce breakage..

21 While accepting the consignment, the grade of eggs must be checked. The carton should be clearly marked with the grade and size. It is advisable to break a few eggs at random to see if they meet the specifications for the grade ordered. This will also help to determine if they have been properly handled by the supplier. Fresh Eggs: This is the preferred form for breakfast cookery. In many kitchens, fresh eggs are used for production. Although the fresh flavour is much desirable for many types of preparation, they create extra labour in handling. They also require more storage space. Frozen Eggs: They are of high quality and available in a number of forms. They are pasteurized while processing, reducing concerns about bacterial growth. They are available as whole eggs, yolks, whites or whole with extra yolks added. These should be thawed under refrigeration. This requires two days. Frozen eggs are excellent for many types of baking, scrambling, omelets, etc. However, in India, pasteurized eggs have not made any head way. Dried Eggs: These are available as whole eggs, yolks or whites. They are used primarily for baking. Dried eggs are not recommended for breakfast cookery. This dried product is not shelf stable. The dried eggs are to be refrigerated or frozen and, tightly sealed. Action of Heat Whole eggs, after being beaten, coagulate at degree centigrade. Thin white part coagulates at 68 degree C and thick white in the range degree C. Yolks coagulate in the range degree C. Whole eggs combined with liquid, such as in custard, coagulate in the range degree C. Storage and Handling Protection of egg is of great importance. When improperly handled, its properties, as an ingredient and independent food item, are impaired. Remember that eggs loose quality when kept long at room temperature. They should always be stored between 18 degree C to 20 degree C. Eggs have porous shells, which allow air to enter the shell. The eggs should be stored away from foods that may pass on undesirable odours. Eggs are best stored in a case to prevent moisture loss.

22 Catering Uses Nutritionally, eggs are important. They contain vitamins A. D, E. K and B complex. They are high in iron and one egg equals one ounce of lean meat, fish or poultry. One large egg provides 15% of the daily requirement of protein. Eggs are low in saturated fat and one large egg is approximately equal to 80 calories. The major concern with eggs is cholesterol. One large egg averages 213 mg of cholesterol. For many people with various health problems, cholesterol is restricted as part of their diet. Although there is no effort to stop cooking with eggs, there is a need to find ways to reduce the cholesterol content of prepared foods. One of the ways is to use egg whites instead of whole eggs, since the cholesterol is in the yolk. Throughout culinary work, eggs are employed in a number of ways. To bind To coat food with bread crumbs. To emulsify - Hollandaise sauce, Barnaise, Mayonnaise. To glaze and colour (egg wash for baking). To aerate-souffls, batters. Egg dishes, no doubt, appear on the traditional menus as a course in their own right and are often chosen as a preliminary item prior to the main dish. However they may also be selected as a main.course item. Milk and Milk Products Types: Whole milk is fresh milk as it comes from the cow, with nothing removed and nothing added. Fresh whole milk is available in several forms. Pasteurized milk: Milk has been heated to kill bacteria at 72 o C for 15 seconds. Raw milk: Raw milk is that has not been pasteurized. It is not often used and, in fact, is generally not allowed to be sold.

23 Homogenized milk: Homogenized milk is processed such that the cream does not separate out. This is done by forcing the milk through very tiny holes, which break up the fat into particles so small that they stay distributed in the milk. The above terms apply not only to the whole milk but also to skim and non - fat milk. Cream Various types of fresh cream, differing primarily in fat content, are available. Whipping Cream: Has fat content of 30-40%; within this category, you may find light whipping cream (30-35%) and heavy whipping cream (36-40%). Light Cream: It is also called table cream or coffee cream and contains 16 to 22% fat, usually about 18%. Half and Half: Has a fat content of 10-20%, too low for it to be called cream. Evaporated Milk: Milk, either whole or skim, is evaporated to remove about 60% of the water. It is then sterilized and canned. Evaporated milk has a somewhat cooked flavour. Condensed milk: Condensed milk is richer than evaporated milk, because more water has been removed. It can be sweetened or unsweetened. It is available canned and in bulk. Fermented milk products. Fermentation means breakdown of an energy-rich compound like carbohydrate into simpler compounds using enzymes. Let us give two applications of fermentation in food preparation: (i) We shall study shortly how yogurt, a curd like food, is prepared from milk fermented by the action of bacteria, lactobacillus bacteria. (ii) Also, you will see the role of yeast, a living micro-organism as a leavening agent in breads based on its fermenting ability of sugars.

24 Fermented Milk Products: Buttermilk: Buttermilk is fresh liquid milk, usually skim milk, which has been cultured or soured by bacteria. It is usually called cultured butter milk to distinguish it from the original buttermilk, which is the liquid left after butter making. Sour cream: Sour cream is cultured or fermented by adding lactic acid bacteria. This makes it thick and slightly tangy in flavour. It has about 18% fat. Yogurt: Yogurt is a curd like food and is prepared from milk fermented by the action of bacteria, lactobacillus bacteria. Various types of yogurts are prepared with varying amounts of fat, flavour and sweetness. Cheese Two types of cheese are used in the bakeshop, primarily in the production of cheese fillings and cheese cakes. Bakers cheese is a soft; un-aged cheese with a very low fat content. It is dry and pliable and can be kneaded somewhat like dough, generally available in packs. It can be frozen for longer time. Cream cheese is also soft cheese; un-aged, but has a high fat content, about 35%. It is mainly used in rich cheese cakes and in a few speciality products. Acidic Ingredients- Cream of Tartar: it's a common ingredient for meringues or meringue toppings. But what exactly is the stuff? For those of you who have ever wondered...let's take a moment to consider the life, times, and purpose of this unique white powder. What it is: a fine, white, odorless powder. Were I to see it on the counter and not have the benefit of seeing its packaging, I might confuse it with baking powder. Why the name? The chemical name for this substance is potassium bitartrate, or potassium hydrogen tartrate. As you might surmise, the "tartrate" part can explain where the "tartar" came from. I wasn't able to find a good explanation of where the "cream of" came into play, but I should clear up any confusion regarding Tartar Sauce. That name is derived fromtartare, which is a dish for which this sauce a condiment of choice. Though tartar sauce is creamy, it has nothing to do with cream of tartar

25 Where it comes from: Believe it or not...it is a by-product of wine production! I'm totally not kidding. It is formed from the sediment left over in barrels after the winemaking process; once formed, it is scraped off of the sides of the barrels and then cleaned and ground to form cream of tartar. Interesting factoid: it's said that cream of tartar residue has been found in pottery dating back 7,000 years! Food uses: Arguably the most famous use for cream of tartar (or at least the one I've seen and used it for most frequently) is to stabilize egg whites when making meringues or meringue toppings. The cream of tartar not only stabilizes the egg whites and allows them to maintain their texture when whipped into stiff peaks, but it also increases their tolerance to heat, which is very helpful, say, when you put a meringue topped pie or a baked alaska into a hot oven. This allows them to brown nicely, hold their shape, and to not m elt away and expose the delicious interior of these desserts! However, there are other food uses for cream of tartar, including stabilizing whipped cream, preventing discoloration of vegetables which have been boiled, and preventing sugar syrups from crys tallizing (I have never used it for this purpose but am intrigued!). It can also be used as an ingredient which will help activate baking soda (hence you may see it in some cake recipes), and it also sometimes is listed as an ingredient in salt substitute s. Other uses: Cream of tartar can also be used, if you're a hippie, as a homemade cleaner. Mix it with something acidic like lemon juice or white vinegar to form a paste; this can be used to clean metals and porcelain. It can also be combined with hydrogen peroxide to clean rust from metal tools, but I will be completely honest and tell you that I find this boring. Food Additives: A food additive is any substance that a food manufacturer intentionally adds to foods to achieve specific desired effects or characteristics during production or processing. In general, food additives contribute to the shelf life of foods and have made many convenience foods possible. They also maintain the firmness, softness or texture of many foods. Some people prefer to avoid food additives, when possible. If this is your preference, you should read labels carefully and select more foods in the natural foods section of your store. Food additives in ancient times: Many food additives have been used for centuries. For example: The Egyptians used vegetable food colorings The Romans used honey to preserve fruit

26 Salting food was a common practice in the Middle Ages Marco Polo searched for herbs and spices, additives for flavoring foods Types of food additives: Food additives are used for a number of different reasons including food preservation, spoilage prevention, flavor enhancement and to improve nutritional value. There are approximately 3,000 food additives that are classified into six major categories 1. Nutritional supplements Many foods are fortified with vitamins and minerals. The primary reason for this practice is to replace nutrients lost during processing and to prevent deficiency diseases. Some of the common fortifications are: vitamin D in milk, vitamin A in margarine, iron and B vitamins in breads, and iodine in table salt. 2. Preservatives The safe-use period of many foods is greatly extended through the addition of preservatives, which retard spoilage, preserve flavor and color and keep oils from turning rancid. Preservatives protect foods, such as cured meats, from developing dangerous toxins, such as botulism, a food poisoning illness. 3. Flavoring agents These are the most commonly used additives. Some, such as monosodium glutamate (MSG), are used to enhance flavor. Others, like chemical concentrates of a flavor such as strawberry, are used to boost flavor. Flavorings are often used when a natural flavoring is unavailable or too expensive to use in a particular commercial product. 4. Coloring agents These additives are used strictly to make foods more attractive to the consumer. Even some fruits, like oranges, have color added to their skins to make their color match the expectations of consumers. 5. Emulsifiers, stabilizers, and thickeners A large variety of products from this category are used to improve the texture and consistency of foods. Emulsifiers are commonly used to keep ingredients from separating in sauces and salad dressings. Lecithin, gelatin and pectin are commonly used natural emulsifiers. 6. Acids and alkalis These additives are used to neutralize the acidity or alkalinity of certain foods. Citric acid, for instance, might be used to add tartness to certain foods. 7. Sweeteners

27 We only have 4 tastes. These are sweet (like sugar), sour (like lemons), bitter (like strong coffee or tonic water) and salt. Most of us like to eat sweet tasting foods. Food manufacturers can add different sorts of sugars or sweeteners to their products to make them sweeter. Sugar may be bad for your teeth and if you eat too much your body can change it into fat and you will put on weight. Scientists have tried to find or make substances which will make your food sweeter but which do not affect teeth or make people fat. These are called artificial sweeteners. A substance like this would also be very useful for foods made for people who have diabetes. Artificial sweeteners can be added to many different products such as chocolate, jam and chewing gum. Government control of additives: The Food, Drug, and Cosmetic Act of 1938 is the law that sets the standards for food in the United States, while at the same time calling for truthful labeling. This act gives the U.S. Food and Drug Administration (FDA) responsibility for safety and wholesomeness of foods. There have been several amendments to this act, but one, in particular, strengthens it in regard to additives. The Food Additives Amendment of 1958 requires pre-marketing approval for substances intended to be added to foods. This amendment includes the Delaney Clause, which states that no chemical can be added to food if, in any amount, it produces cancer when ingested by man or animal. When the Food Additives Amendment of 1958 was adopted, over 200 substances were exempted from the testing requirement because they were considered to be Generally Recognized as Safe (GRAS). A number of other substances have been added to this list since its initial adoption. Allergies and sensitivities to additives: Some people have an immediate reaction to food preservatives, such as BHA, BHT, MSG, nitrites, sulfites, sodium bisulfite, and sulfur dioxide. Some of these reactions are due to allergies. With allergies, preexisting antibodies in the body react to the chemical molecules and cause a variety of problems, ranging from mild skin rashes to gastrointestinal upset to life-threatening anaphylactic episodes. Other reactions reflect an intolerance to the food or additive; rather than an allergy per se, but these reactions may still be uncomfortable. An example of such a reaction would be a person who gets a headache after eating MSG. Fruits and Nuts: Nearly any kind of fresh fruit can be used in the production of deserts. In addition, a wide variety of dried, frozen, canned and processed fruit products are important ingredients in the bakery. Fresh Dried Canned and Frozen Candied Apple Figs Apple Cherries Banana Dates Peaches Lemon peel

28 Lime Prunes Apricot Orange peel Lemon Apricots Strawberries Pineapple Orange Raisins Cherries Figs Papaya Cherries Pineapple Mango Currants Mango pulp Passion fruit Leeches Pears Peaches Kiwis Apricot Grapes Nuts are available whole, halved, or crushed / powdered. Almonds Coconut Walnut Hazelnut Peanut Cashew Chest nut Nut Pastes Marzipan: Essentially a sweetened almond paste, used in decorative and confectionery work. This product can be purchased or made in the bakery from almond paste. Praline paste:

29 This is a confectionery paste made from almonds and / hazelnuts and caramelized sugar, all ground to a paste. It is used as a flavouring agent for icings, fillings, pastries and creams. Kernel paste: It is a product similar to almond paste but less expensive. It is made from apricot kernels, which have a strong almond like flavour. Extracts and Emulsions: Extracts are flavoured oils and other substances dissolved in alcohol. This may include bitter almond, vanilla and lemon. Emulsions are oils with flavour, which are mixed with water with the aid of emulsifiers such as vegetables gums. Lemons and oranges are most frequently used in emulsions. Flavourings in general may be divided into two categories: natural and artificial. Natural flavourings are costly but quite superior in value. Cocoa and Chocolate Chocolate liquor contains a white or yellowish fat called cocoa butter. After part of the cocoa butter is removed from chocolate liquor, cocoa remains as the dry powder. Sweet chocolate: Sweet chocolate is prepared from bitter chocolate by the addition of sugar and cocoa butter in various proportions. Milk Chocolate: It is a sweet chocolate which contains added milk solids. It is usually used as a coating chocolate and in various confections White chocolate: Cocoa butter, sugar and milk solids are used in preparing white chocolates. It is used primarily in confectionery.

30 Enzymes in Baking: Enzymes play an essential part in modern baking technology and have done so for many years. In many baking improver formulations enzymes are key technology products. Enzymes used as processing aids in baking are the key differentiation factor for bakery improver manufacturers and a great source of product innovations and differentiation. The dough for bread, rolls, buns and similar products consists of flour, water, yeast, salt and possibly other ingredients such as sugar and fat. Flour consists of gluten, starch, non-starch polysaccharides, lipids and trace amounts of minerals. As soon as the dough is made, the yeast starts to work on the fermentable sugars, transforming them into alcohol and carbon dioxide, which makes the dough rise. Gluten is a combination of proteins that forms a large network during dough formation. This network holds the gas in during dough proofing and baking. The strength of this gluten network is therefore extremely important for the quality of all bread raised using yeast. Enzymes such as hemicellulases, xylanases, lipases and oxidases can directl 201- Food Production & Bakery -I (Th) Unit-4 Egg Cookery Certain foods play a major role in cooking. One of them is egg. It can be served as a main dish or as an accompaniment to other dishes or as an ingredient in another item. Due to its versatility, the egg is considered a primary ingredient in culinary preparation, providing moisture, structure and richness in dishes. It is also an emulsifier and aerator, when properly handled and used. In cooking, the term egg refers to the oval, thin-shelled ovum of a bird, used as food. There are many types of eggs, such as those of goose, duck and turkey. In this unit, we are most concerned with the eggs of the chicken. Composition

31 Let us study the composition of egg Composition of an Egg The shell or outer covering of the egg may be white or brown. Shell color has no relation to the quality, working properties or the nutritive value of the egg. The colour of the shell is determined by the breed of the chicken. Composed primarily of calcium carbonate, the shell is very fragile. It is porous, which allows it to breathe. The porous nature of the shell allows loss of moisture, even if unbroken. The white part is the food and the moisture source for the embryo in a fertilized egg; it accounts for 67% of liquid weight of the egg. Egg white is made up of two parts: a thick white liquid and a thinner liquid part. Albumin, a protein, is the major component of the white. This protein also contains sulphur.

32 Albumin, in the egg white, is valued by the cook and baker for its ability to hold air, when beaten. Besides, egg white provides light fluffy texture for souffle s, chiffon pies, angel food cakes and other food items. The yolk is the unfertilized embryo in the egg and is yellow in colour. The depth of colour will vary with the feed of the hen. The yolk is high in fat and protein and contains iron. The yolk is valued for the richness and texture, which it provides in both cooking and baking. Primarily, an egg is graded by weight: Grade A around 70 grams Grade B around 60 grams Grade C around 50 grams Purchasing Factors Purchase only the quantity of eggs needed for one or, at most, two weeks; accept only eggs which are clean, sound and odour free. There are various methods of preserving eggs, such as oiling, wrapping and refrigeration. However, the preferred method is refrigeration. Exposure to temperatures above15 degree C shortens the life of an egg. Higher temperatures often break down an egg white and yolk. Fresh eggs should be properly boxed. The best packaging for the commercial kitchen is fiberboard boxes. Eggs should be packed in the carton in snug fitting trays to reduce breakage.. While accepting the consignment, the grade of eggs must be checked. The carton should be clearly marked with the grade and size. It is advisable to break a few eggs at random to see if they meet the specifications for the grade ordered. This will also help to determine if they have been properly handled by the supplier. Fresh Eggs: This is the preferred form for breakfast cookery. In many kitchens, fresh eggs are used for production. Although the fresh flavour is much desirable for many types of preparation, they create extra labour in handling. They also require more storage space. Frozen Eggs: They are of high quality and available in a number of forms. They are pasteurized while processing, reducing concerns about bacterial growth. They are available as whole eggs, yolks, whites or whole with extra yolks added. These should be thawed under refrigeration. This requires two days. Frozen eggs are excellent for many types of baking, scrambling, omelets, etc. However, in India, pasteurized eggs have not made any head way.

33 Dried Eggs: These are available as whole eggs, yolks or whites. They are used primarily for baking. Dried eggs are not recommended for breakfast cookery. This dried product is not shelf stable. The dried eggs are to be refrigerated or frozen and, tightly sealed. Action of Heat Whole eggs, after being beaten, coagulate at degree centigrade. Thin white part coagulates at 68 degree C and thick white in the range degree C. Yolks coagulate in the range degree C. Whole eggs combined with liquid, such as in custard, coagulate in the range degree C. Storage and Handling Protection of egg is of great importance. When improperly handled, its properties, as an ingredient and independent food item, are impaired. Remember that eggs loose quality when kept long at room temperature. They should always be stored between 18 degree C to 20 degree C. Eggs have porous shells, which allow air to enter the shell. The eggs should be stored away from foods that may pass on undesirable odours. Eggs are best stored in a case to prevent moisture loss. Always refrigerate eggs in closed containers because the shells of eggs being very porous allow passage to moisture, bacteria and mould, if left uncovered for any length of time. When there are a few eggs left in the fridge and you buy more eggs, there is a need to avoid confusion. To distinguish the old ones from the new, mark the old eggs with a pencil or a sketch pen with a number or a particular sign. The freshness of the eggs can be ascertained using the water - immersion test

34 Test for Freshness of an Egg. Catering Uses Nutritionally, eggs are important. They contain vitamins A. D, E. K and B complex. They are high in iron and one egg equals one ounce of lean meat, fish or poultry. One large egg provides 15% of the daily requirement of protein. Eggs are low in saturated fat and one large egg is approximately equal to 80 calories. The major concern with eggs is cholesterol. One large egg averages 213 mg of cholesterol. For many people with various health problems, cholesterol is restricted as part of their diet. Although there is no effort to stop cooking with eggs, there is a need to find ways to reduce the cholesterol content of prepared foods. One of the ways is to use egg whites instead of whole eggs, since the cholesterol is in the yolk. Throughout culinary work, eggs are employed in a number of ways. To bind To coat food with bread crumbs. To emulsify - Hollandaise sauce, Barnaise, Mayonnaise. To glaze and colour (egg wash for baking). To aerate-souffles, batters. Egg dishes, no doubt, appear on the traditional menus as a course in their own right and are often chosen as a preliminary item prior to the main dish. However they may also be selected as a main.course item. e.g., Omelets, curried eggs. Meat Cookery Different type of meat are : lamb, mutton, beef, veal, pork. It order to cook meat it is important to know the structure of the meat. Factors that give meat a good quality 1. Fat : The fat present in meat indicates the quality as it gives a good flavour. Fat in animals is found around or between muscles fibers. Fat contributes moistness to the meat, makes it tender, enhances flavour & makes it tender & juicy.

35 2. Colour of Meat : Older the animals have darker coloured meat & yellowish fat, where as younger animals have a lighter coloured meat with a firm, dry, creamy white fat. 3. Tenderness : The tenderness of meat depends upon the food animal is fed on. The finer the grain tender will be the meat. The amount of connective tissues is directly related to the tenderness of meat. Meats are of various types; some of the popular ways of classifying meat are as follows: By the cuts - sirloin of beef, saddle of lamb. By the condition of meat fresh, chilled, frozen, pickled. By the age and sex - steer (an ox less than four years old) beef, bull beef, cow beef By the type of animal bovines (the ox or cow) (beef/veal), porcine (relating to swine) (pork), Ovine (relating to sheep) (mutton) By the catering uses - For roasting, for frying, for grilling, for boiling Slaughter of Animals In India slaughtering of animals is done in three ways; viz: 5) Jhatka II. Halaal III. Stunning Jhatka: It is a method of slaughtering an animal by chopping the animals neck part by a single stroke of the huge chopper (talwar); this is practiced by the Hindus, especially the Punjabis of the Northern India. Halaal:

36 It is the method of slaughtering an animal by means of a sharp knife (Blade and not saw). This is done by slowly slitting the neck of the animal, so that the blood flows easily out of the animal. Here the head is not separated from the body of the animal. Only when the animal dies, its head is removed. This is practiced by the Muslims round the globe. More than 70% of the slaughter houses in India practice this method, because most of the butchers in India are Muslims. Stunning: Captive Bolt: This is the stunning of the animal by a captive bolt pistol and is used for large animals such as bovines & pigs. Electrical Stunning: This method is the passing of a small current of electricity through the head of small animals for at least 7 seconds. It is done by applying a pair of special tongs, connected to an electricity supply, behind the ears of the animal. Carbon dioxide stunning: This method is used for stunning pigs. The pigs are placed on a moving platform which passes through a tunnel containing mixture of CO2 and air. 1. Moist Heat : Factors that make meat tender White connective tissues are called as collagen which changes into gelatine when moist heat is applied on it. Yellow connective tissues are called elastin & this does not change by cooking or marinading. 2. Tenderizers : When used tenderizers make the meat tender. Commercial tenderizers contain enzyme such as papain, an enzyme found in raw papaya and its leaf. Acidic food like vinegar, tomato, curd, lemon & tamarind help tenderize the food also. 3. Ripening or Ageing of Meat : Meat should not be eaten immediately after killing as rigour mortis sets in & stiffens the muscles. The muscles are hung in cool conditions 1-2 degree Celsius time period depend upon the type of meat. There is an improvement in tenderness, flavor, moisture & colour. Veal & pork are not hung. 4. Marinating :

37 Tough meats soaked in an acidic solution i.e. Wine, vinegar or curd make the meat tender & enhance the flavor. Beef How to judge the quality of the various Meats 6) Fresh meat must be hung to allow it to become tender. The color darkens after it has been hung. 7) Lean meat should be bright red. 8) The fat should be form, brittle in texture, creamy white in color. Veal The flesh should be pale, firm not soft. Cut surface should be moist. Bone in young animal is pinkish, porous & with very small amount of blood in their structure. Lamb 1. Carcass should be compact & evenly fleshed having an even coat of fat. 2. Bones are porous in young animals as age progresses they are smooth. 3. Fat should be evenly distributed, hard, brittle & white in color. Pork 1. Lean flesh should be pale pink changing to rose as the animal matures. 2. The fat is white, firm, smooth & not excessive. 3. Bones must be small, slender & pinkish. Lamb Cuts Lamb is a meat of young sheep & mutton the flesh of the mature sheep or goat. Lamb usually is the flesh of animals not more than 14 months of age. The average weight of an

38 imported lamb is approx 32 lbs (16 kg). The average weight of an Indian lamb is 10 kg to 14 kg & for mutton it is between 20 kg to 25 kg. Dissections of Joints Lamb/Mutton 1. Remove the shoulder. 2. Remove the breasts. 3. Remove the middle neck. 4. Remove the scrag-end. 5. Remove the legs.

39 Divide the best end from loin. Pork The flesh of pig is called pork. Most of the pork meat comes from animals not more than a year old. It generally has more fat than other meats. A suckling pig is about 5-6 weeks old. First quality of pig are the leg & loin of pork. Order of Dissection 1. Remove the head. 2. Remove the trotters. 3. Remove the legs. 4. Remove the shoulder. 5. Remove the spare ribs. 6. Divide the loin from the belly. Ham It is taken from hind leg of pig preserved by curing or pickling in brine, then dried & smoked. Ham is prepared from fresh pork meat. Boiling of ham is done by placing in cold water first & soaking it. Then it is placed in suitable container and boiled slowly. Ham after boiling can be decorated with chaud-froid sauce. Gammon is taken from the leg of pig that has been reared for bacon. Bacon Bacon is obtained from the sides & back of a baconer. The bacon is obtain by taking the meat & preserving the meat by salting. After the meat has matured the bacon is sold as green bacon. Smoked bacon is very popular & this is done in smoke chambers, which gives flavor & help to [reserve for longer time.

40 Beef Beef & veal are got from cattle animals they are classified by their ages :- 1. Veal - Flesh of calf ( less than 3 months of age) which lives on milk. 2. Calves - the animals are from 3-8 months old. 3. Beef - The meat is taken when the animal is above 8 months.

41 Beef is the most popular of all edible meat in the western countries. In India, beef is not very popular.the age & sex has an influence on the taste & quality of meat. Order of Dissection : Beef Cuts The carcass is divided into two lengthwise. For Hindquarters : 1. The whole side is divided between the wing ribs & the fore ribs. 2. Remove the rump suet & kidney. 3. Divide the loin & rump from the leg ( topside, silver side, thick flank & shin) 4. Remove the fillet. 5. Divide the rump from the sirloin. 6. Remove the wing ribs. 7. Remove the shin. 8. Bone cut the aitch bone. 9. Divide the leg into three remaining parts ( silver side, top side & thick flank) For Forequarters : 1. Remove the shank. 2. Divide in half down the center 3. Divide into joins. Beef Terms : 1. Carcass - Whole animal after dressing from slaughter house. 2. Side - A carcass that has been split down the center of the spinal column. 3. Quarter - A side that has been subdivided into two sections as forequarters & hindquarters. 4. Offals - Products derived from the process of slaughtering other then carcass, the edible internal organs like liver, heart, kidney,tail, brain etc.

Poultry Poultry is the name given to domestic birds specially bred to be eaten. It includes different varieties & sizes of chicken, turkey, ducks, geese etc. Drawn poultry loses approx. 25% of its original weight. The word Volaille in french means poultry but when it appear to the menu it means chicken. Signs of a fresh & Young Chicken 1. Soft fluffy feathers should be all over the body, especially concentrated under the wings. 2. The quills of the feathers should be easy to pull out. 3.

46 Fish Cookery Fish provides many attractive & satisfying dishes. Fish is high protein food. Fish could be obtain from lakes, rivers, sea. Fresh water fish are considered to be superior in flavor to salt water fish. The season also have bearing on the fish for better taste. The fat content helps in determining the method of preparation. The fish which have fat will produce superior eating qualities if baked or boiled. Lean fish are best when poached or steamed. Fumet de poisson is concentrated fish stock. Classification of fish 1) White fish ( round) a) Round - cod, haddock, hake, chamli & turai It has oil in the liver Lean ( Flat) b) Flat - Pomfret, sole, turbot, sangara 2) Oily Fish Salmon, mackerel, herrings, salmon trout, trout. Shell fish is subdivided into oyester. ( Immobile) 1) Molluscs - Clams, mussels, scallops & 2) Crustaceans - Crayfish, lobsters,

47 prawns, shrimps ( mobile) How to choose Fish 1) The condition of the fish should be shiny & of good colour. 2) In white fish the flesh should be really white not faintly yellow. 3) The body should be rather heavy in relation the length & the flesh plump & springy. 4) Eyes should be bright & not sunken. 5) Gills should be red. 6) For freshness the flesh should have pleasant, slightly salty smell, which increases with its staleness. 7) If the imprint of the finger remain after it has been pressed then it is not fresh. 8) If the scales come out by themselves then the flesh is stale. 9) Raw flesh should not come out from bones. 10) The tail should be stiff. Fish should be stored at 1 degree Celsius. Preparation of fish for cooking 1) soaking the fish in cold water for few minutes before descaling. 2) The blunt side of the knife should be used. 3) The head of the fish is held with left hand & holding the knife vertical, scraping is done starting from the tail towards head. 4) Cut off the fins, remove the head. The entrails should be removed by cutting the length of the fish from vent end to head on the belly side. Filleting Cut the flesh along the line of the backbone & raise the fillet from the middle of the back to the sides, first working towards the head, then the tail. Skinning Hold the tail end of the fish in the left hand, first sprinkling salt on fingers for good grip. Skin the flesh from tail to head with quick short sawing of a sharp knife. Point the knife blade towards the skin so that no flesh is wasted. Fish Cuts

Boiling Cooking Methods -This method is suitable for the whole fish e.g- surmai, salmon etc. Thick cuts of the fish should be boiled. Whole fish cleaned should be putted in court bouillon & boiled. The whole fish should be wrapped in cheese cloth & to retain the shape. Liquor should be sufficient to over the fish. Bisque - It is rich classical soup made from shellfish,shells, tomato, brandy & cream. Steaming - For steaming the fish should be well seasoned & sprinkled with lemon juice to keep flesh white. Greased proof paper should be put in the bottom of the steamer before cooking. This help in lifting the fish & does not allow it to stick. It should be well drained before service & accompanied by well seasoned sauce. Poaching -This method of cooking is suitable for small whole fish, cuts or fillets. Court bouillon should be used for poaching. The poaching liquor covers the fish covered with grease proof paper & poached in the oven. Baking -Round white fish is suitable for baking. The fish should be cleaned & the belly is stuffed with force meat (bread crumbs, chopped onions, nutmeg, lemon rind, egg yolk, a little butter, seasoning) & edges are sewed. Butter is applied to the fish & then it is baked in baking tray. Frying -Small whole round of flat fish, goujons & fillets are suitable for deep frying. As the flesh is very delicate, the fish must be coated before frying. The following are the coatings normally used :- a) Flour, egg white & bread crumbs. b) Milk & Flour. c) Flour Batter. d) Flour & beaten egg. Shallow Frying - Fillet, tron con, supreme are shallow fried. The fish is coated with seasoned flour & shallow fried in butter. Grilling -It is suitable method for various cuts & types of fish. They are seasoned & cooked over heat on the grill or in a salamander.

50 The grill should be greased so that the fish does not stick. Fish do not need any extra basting. Grilled fish is garnished with lemon & parsley. Stewing -Bouillabaisse is a french regional stews in which a mixture of different fish are used. Pieces of fish & shellfish with vegetables, herbs & fish stock are cooked & the cooking liquid is not thickened. Milk and Milk Products Milk is considered as the best wholesome food for one and all. It contains the much needed nutrients, vitamins and proteins for healthy development of body and is high in energy and rich in diet. Types of Milk 1) Pasteurized milk - Milk which is generally heated at 72 degree centigrade for about 15 seconds to kill bacteria & then cooled quickly. 2) Ultra Heat Treatment (UHT) - Milk which is generally heated at132 degree centigrade for about 1 second. They can be commercially tetra packed and can be stored for almost 6 months if unopened. 3) Homogenized milk - The milk is treated through a high pressure vat where the fat globules are allowed to mix-in and set so that the cream gets dispersed throughout the milk. 4) Sterilized milk - This is a type of homogenized milk which is heated to around 104 degree centigrade for about 30 seconds. 5) Evaporated milk - has had 60% of the water removed by evaporation before canning. Condensed milk is richer than evaporated because more water has been removed. It can be sweetened or unsweetened. 6) Dried milk - It is either spray or roller processed. Uses of milk The milk is used for the following purposes: 1) Soups and sauces 2) Cooking of vegetable, making cakes and sweets 3) Making of puddings

51 4) Cold drinks - milk shakes and malts 5) Hot drinks- tea, coffee, cocoa and chocolate. Milk Products: There are various types of milk products. We shall study them one by one in brief as detailed below: 1. Cream This is the concentrated skimmed milk. Creams are of different varieties. They are given below: 1) Single Cream: It contains18% fat and does not whip easily, but can be used in liquid state with sweet dishes and for finishing soups, fish, meat and poultry. They are also used for thickening sauces and stews. 2) Whipping Cream: It contains 30-40% fat and are meant for whipping purposes. 3) Double cream: It contains 48% fat and is used for decorating and filling pastries, gateaux and with sweet dishes. 4) Devon or clotted cream: It contains 55% fat and is costlier when compared to other forms of creams. 5) Imitation Creams: These creams resemble other creams in appearance but they are produced by emulsion of oil, margarine or butter with milk powder and water. They are used for filling and decorating cakes and finishing sweet dishes. Uses of Cream 1) Fresh cream must be cold when required for whipping. 2) For preference it should be whipped on china or stainless steel bowls. If any other metal is used, the Cream should be transferred to china bowls as soon as possible. 3) If fresh cream is whipped too much, it turns to butter. This is more likely to happen in hot conditions. To prevent this, stand the bowl of cream in a bowl of ice while whisking. 4) When adding cream to hot liquids, dilute the cream with some of the liquid before adding to the main bulk. This helps to prevent the cream from separating. 2. Yogurt

52 Yogurt is a curd like food and is prepared from milk fermented by the action of bacteria, lactobacillus bacteria. Types of Yogurt: 1) Fat free yogurt - contain less than 0.5% milk fat. 2) Low fat yogurt - contains maximum 1.5% milk fat. 3) Whole milk yogurt - contains fat as in whole milk. 4) Whole or real fruit yogurt - contains whole fruit in sugar syrup. 5) Fruit flavoured yogurt - contains fruit juices or syrup. 3. Butter Butter is produced by churning the cream of milk. One liter of cream yields approximately half kg butter. Butter must be kept away from strong smelling foods. Butter is an energy food as it has a very high fat content. Quality 1) The taste should be creamy and pleasant. 2) The texture should be soft and smooth. 3) It must smell fresh. 4) The colour of pure butter is almost white or very pale yellow. 5) Fresh butter should be used fairly quickly, otherwise it goes rancid (acquires an unpleasant taste and smell). 4. Cheese Cheese making has been dated back over five thousand years. The nomads (a group of people who have no fixed residence but move from place to place usually seasonally and within a well-defined territory) of the Middle East were the first skillful cheese makers. Cheese even played a part in Greek mythology. Cheese was a staple part of every Romans diet but the production of cheese started to flourish when the French monasteries were created. The use of milk from a goat, sheep, or cow and an enzyme resulted in whey (the watery part of milk rich in lactose, minerals, vitamins and protein with traces of fat). What is Cheese?

53 All cheese is made from milk, but different manufacturing and aging processes are used to produce the array of cheese available today. Cheese is made by coagulating or curdling milk, stirring and heating the curd, draining off the whey, collecting and pressing the curd, and in some cases ripening. Cheese can be made from whole, 2% low fat, 1 % low fat or fat-free milk, or combinations of these milks. About one third of all milk produced each year in the United States is used to make cheese. Cheese Components There are four components that are used in making cheese: 1) Milk a) Starter cultures (material containing microorganisms (as yeast) used to induce a desired fermentation) b) Coagulants and rennet (materials used for separating the solids in the milk and gathering them together as a single mass) c) Salt Importance of Milk in Cheese Making Milk is the most important ingredient of cheese and the type of milk determines the type of cheese that can be produced. For example, milk containing high total solids (sheep) increases cheese yields, and conversely, milk high in fat produces softer cheese, but improves the mouth-feel of the product. Process of making cheese The process used is same for making many varieties of cheese. But, the type of milk used and the ripening and maturation can greatly influence the resulting cheese. The figure given below illustrates the primary stages of cheese production.

54 Storage of milk products 1) Fresh milk, cream, buttermilk, other fermented milk products and cheese must be kept refrigerated at all times. 2) Evaporated milk in large container will keep for a week or more after opening, if kept covered and in a cool place. The sugar acts as a preservative. Stir before using, because the sugar tends to settle to the bottom and sides. 3) Dried milk should be kept in a cool, dark place. It does not need refrigeration, although you should store it well away from ovens and other heat sources. Keep the containers tightly closed to prevent the milk from absorbing moisture from the air. Fruits and Vegetables Fruits For the purpose of catering, fruit may be divided in to the following: 1) Soft fruits - Raspberries, strawberries, gooseberries, blackberries. 2) Hard fruits - Apple, Pears 3) Stone fruits - Cherries, damsons, plums, peaches, mangoes. 4) Citrus fruits - Oranges, lime, grape fruit, Mandarins, tangerines 5) Tropical & other fruits - Pine apple, banana, figs, grape, Melon etc.

55 Storage of fruits: 1)Hard fruits such as apples are best left in boxes and in a cool store. 2) Soft fruits, such as raspberries should be stored in pun nets or basket in a cold room. 3) Stone fruits are best placed in trays so that any damaged fruits can be replaced. 4) Peaches are best left in their delivery trays or boxes. 5) Bananas should be stored in room temperatures and never in a too cold room. Preservation of fruits: Preservation of fruits is done through canning, bottling, candied, glace, crystallized, drying and quick freezing. Vegetables Vegetables are the fundamental food for many people now a days, may be because of the health factor. Even though meat eaters love non-vegetarian dishes, they do relish the vegetables as an accompaniment. Can anyone imagine the world without vegetables? Classification of vegetables They may be classified in to various ways. For our understanding, let us simplify it as under: 1) Tubers and roots 2) Shoots and stalks 3) Grass & blade 4) Bulbous 5) Fruit 6) Nuts & kernels 7) Algae & fungus 8) Sea vegetables 9) Leaves & greens

56 10) Fresh & dry Cuts of Vegetables: The size to which the vegetables are cut may vary according to their use. In Fig 4.6, cuts of vegetables are shown. 1) Dices : The pieces of potatoes and carrots which are cut length wise and then cut small, medium or large cubes. 2) Allumette : These are finger - like cuts usually obtained from potatoes.e.g. cut for French fries or finger chips 3) Julienne (strips) Cut the vegetables into 2 cm (1 inch) lengths. Cut the lengths into thin slices. Cut the slices into thin strips. 4) Brunoise (small dice) Cut the vegetables into convenient-sized lengths. Cut the lengths into 2 mm slices.. Cut the slices into 2 mm strips.. Cut the strips into 2 mm Squares. 5) Macedoine (1 cm dice) Cut the vegetables into convenient lengths.
