IS : 3581 1982 Indian Standard GRADING FOR GREEN COFFEE ( Second Revision ) 0. FOREWORD 0.1 This Indian Standard ( Second Revision ) was adopted by the Indian Standards Institution on 8 January 1982, after the draft finalized by the Stimulant Foods Sectional Committee had been approved by the Agricultural and Food Products Division Council. 0.2 This standard was first published in 1966. The first revision of the standard was brought out in 1974 to include determination of moisture content with a view to aligning it with the practical method adopted by the ISO. The present version of the standard reflects the latest trade practices followed by the Coffee Board with respect to grade designations. 0.3 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS: 2l%O*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. 1. SCOPE 1.1 This standard prescribes the requirements for different types and grades of green coffee, namely, co$a arabica Linn. and Coffea caenophora ( subvariety C. robusta Linden ). 2. TERMINOLOGY 2.0 For the purpose of this standard, the following definitions shall apply. 2.1 Plantation Triage Broken, withered, spotted, elephant, small discoloured malformed beans, pales and pulpercuts. 2.2 Robusta Parchment and Cherry Triage Round small beans, spotted beans, dried and shrivelled beans, broken beans ( not less than *Rules for rounding off numerical values ( revised ). 3
onethird of a bean in size ). In the case of Robusta Parchment Triage, pales and pulpercuts are also included. 2.3 Bits Broken coffee of less than one third of a bean in size. 2.4 Blacks More than a quarter of a bean surface black, blue, brown or similarly discoloured beans and including stinkers and sour beans. 3. VARIETIES AND TYPES 3.1 There are mainly two varieties of coffee as given below: a) Variety ICo$ea arabica Linn., and b) Variety IICO&X cacnobhora ( subvariety C. robusta Linden ). 3.2 There shall be four types of coffee as given below: a) Arabica, Plantation ( washed ); b) Arabica, Cherry ( unwashed ); C) Robusta, Parchment ( washed ); and d) Robusta, Cherry ( unwashed ). 3.2.1 There shall be seven grades of Arabica Plantation as given below: a) Plantation PB c) Plantation B e) Plantation C b) Plantation A d) Plantation Bulk f) Plantation Bits g) Plantation Blacks 4. REQUIREMENTS 4.1 Moisture Content When determined by the method prescribed in Appendix A, the moisture content in coffee at the time of packing shall be as follows: a) Washed Coffee, Arabica, Plantation and Robusta, Parchment, Max 10 percent b) Arabica, Cherry, Max 11 percent c) Robusta, Cherry, Max 11 5 percent 4.2 Freedom from Infestation Coffee beans shall be free from infestation due to insects, fungi and rodents. 4.3 Freedom from Extraneous Matter Coffee beans shall be free from any extraneous matter, such as strings, stones, dirt, wood and glass, and metallic pieces. 4.4 Odour Coffee beans shall be free from any foreign odour. 5. GRADES 5.1 Coffee beans shall be graded on the basis of size and shape before packing. 4

fs : b8i 1982 6. PACKING AND MARKING 6.1 Packing The coffee beans shall be packed in new, clean and sound jute or lined bags or any other suitable container as agreed to between the purchaser and the vendor. The bags shall be free from any fungal. or insect infestation and shall be free from any undesirable smell. 6.2 Marking The following particulars shall be marked or labelled_on each bag: 4 b) c> 4 Name of the material, Variety and type, Grade of the material, Name and address of the vendor, and e) Net mass in kg. APPENDIX ( Clause 4. I ) A DETERMINATION OF MOISTURE AO. PRINCIPLE A0.1 Dry the sample of beans at a temperature of 130 & 2 C, at atmospheric pressure, in two stages with an intermediate rest period, in order to redistribute uniformly the moisture in the bean. Al. APPARATUS Al.1 Electrically Heated ConstantTemperature Oven The oven shall have effective ventilation and shall be regulated in such a way that the temperature of the air and of the plates carrying the samples is 130 & 2 C in the vicinity of the samples. The oven shall have such heating capacity that when it is previously set at a temperature of 13O C, it is again able to reach this temperature in less than 45 min ( preferably in less than 30 min ) after the insertion of the maximum number of test portions that can be dried simultaneously. A1.2 Dish with Lid This shall be of corrosionresistant metal or of glass, with an effective surface area of at least 18 cm2 ( for example, 50 mm minimum diameter and 25 to 30 mm deep ). A1.3 Desiccator Phosphorous pentoxide, reagent grade, or any other effective dehydrating agent shall be used in the desiccator. 6
IS t 3581 1982 Al.4 Analytical Balance A2. PROCEDURE A2.1 Test Portion Weigh the empty dried dish with its lid. Introduce approximately 5 g of green coffee beans and spread them over the bottom of the dish in a single layer. If the test portion contains a large quantity of impurities ( nails, stones, wood, etc ), discard the test portion and take a fresh portion from the laboratory sample. Cover the dish with its lid and weigh the dish with lid and the test portion to the nearest OS000 2 g. A2.2 Determination A2.2.1 First Period in the Oven Place the dish containing the test portion in the oven at a temperature of the 13O C, on its lid. Remove it after a period of 6 h f 15 min; cover it with the lid while still in oven and place it in the desiccator. After cooling to ambient temperature ( from 30 to 40 min after placing it in the desiccator ), weigh it, still closed. After weighing, replace the dish in the desiccator for at least 15 h. A2.2.2 Second Period in the Oven Under the same conditions as specified in A2.2.1, replace the dish in the oven at a temperature of 130 C and let it remain there for 4 h f 15 min. Remove it, allow it to cool to ambient temperature in the desiccator and weigh again. A2.2.3 Xumber of Determinations Carry out at least two determinations on the same sample till the difference in results of last two determinations is not more than 0.3 g of moisture per 100 g of the sample. A3. CALCULATION A3.1 The percentage of moisture in the sample shall be calculated by adding the percent loss in mass calculated after the first period in the oven ( see A2.2.1 ) and half the value of the addition percent loss in mass calculated after the second period in the oven ( see A2.2.2 ). A3.1.1 Loss in Mass after the First Period in percent loss in mass using the following formula: where 100 PI= (m, ml) x m0 Oven ( PI ) Calculate m. = initial mass in g of the test portion, and ml = mass in g of the test portion after the first 6 h period. :7
ISt3581.1982 A3.1.2 Loss in Mass after the second Period in Oven ( Pe ) Calculate percent loss in mass using the following formula: where 100 P2 = ( m, ms ) x m. m, = initial mass in g of the test portion, and m2 = mass in g of the test portion after the second 4 h period in the oven. A3.1.3 Moisture Content, Percent by Mass (P) Calculate moisture content ( percent by mass ) using the following formula ( see Note ): P = p1 f pa ; pl NOTEThe difference between the losses in mass observed after 6 h ( se8 A2.2.1 ) and 10 h ( including additional 4 h ) ( see A2.2.2 ) in the oven at a temperature of 130 C. that is, the difference between PI and P2, should normally be less than 1.0 g per 100 g of sample. 8
