Beverage Weighing and Analysis in the Laboratory 2 News It s all About the Right Concentration at PepsiCo In the soft drinks industry it s all about the right concentration of ingredients, such as acids or sugars in syrups and concentrates and accurate and reliable yet speedy test results are a must. That s why PepsiCo relies on METTLER TOLEDO Titrator systems, which automate the whole process of analysis and therefore save considerable time. Guaranteeing brand quality PepsiCo International in Cidra, Puerto Rico is the world s largest manufacturer of syrups and concentrates for Pepsi-Cola, Tropicana and Gatorade. After production, syrups and concentrates are shipped to local bottling companies. The bottlers dilute them to produce the beverages which are sold to the public. With this procedure PepsiCo can guarantee that their brand of beverages taste the same all around the world. The Cidra plant employs around 140 people in a two shift production line and about 14 people in a two shift QC lab. There are two sections in the QC lab taking care of intermediate products such as syrups and concentrates and of locally bottled end products. Automation makes the difference In order to carry out a precise titration, several steps need to be followed. A suitable sensor is required which must be calibrated periodically, the concentration of the titrant has to be known, and finally, a suitable method and various parameters have to be entered into the Titrator. The automation of such steps makes the laboratory staff more efficient and offers time-saving solutions, as one can work on other tasks during this time. Laboratory managers are also less pressurized as they don t have to check the performance of each individual step. Everything from electrode calibration and titer determination to the actual determination of the different acids is automated with the Rondo sample changer.

As quality is so important, the laboratory calibrates the electrodes on a daily basis and performs the titer determination of the sodium hydroxide once per week. Together with all the different samples to be tested, this keeps them pretty busy. Thus, the possibility of automation, to maintain the productivity of the QC lab, was very welcome. Many applications and one reliable service I called METTLER TOLEDO yesterday, and within one day Kevin showed up to help me with the new instruments. This gives us the security that our customers never have to wait for our analyses. You know, actually it is the best service you can get. explains Ivonne Ferrer. This was the main reason why PepsiCo recently bought two new METTLER TOLEDO DL55 Titrators with two Rondo 60 sample changers and are about to purchase three METTLER TOLEDO refractometers. Another positive point to note is the security of instrument operation. METTLER TOLEDO supports this through reliable user management. With the DL55 Titrator systems, every user can log on with his username, which will be printed with every result together with date and time. Even the small and space saving RS-P42 printer prints this information along with sample results. Apart from titration, PepsiCo is also measuring ph and conductivity values with the combined MPC 227 meter, InLab 413 and InLab 730 electrodes. Measuring the refractive index is another useful parameter mainly used for fast and accurate determination of sugar content (BRIX) of concentrates and beverages. Ivonne Ferrer concludes, What we like especially about all the titrators, refractometers, ph meters and balances is that there is only one company which takes care of every single issue with these instruments. From service, to sales and to after-sales-support - METTLER TOLEDO has it all. www.mt.com/titration Subject to technical changes. Mettler-Toledo AG 07/06 Printed in Switzerland. 2
Moisture Analysis Instant Moisture Analysis for Great Tasting Coffee A concentrate of freshly brewed coffee is dried by spray-drying or freezing, resulting in soluble powder or granules and marketed as instant coffee. No matter which process is chosen, moisture content plays a crucial role for the quality of the coffee. With the HR83 Halogen Moisture Analyser moisture content is monitored throughout the entire coffee production, from green beans to instant coffee. Keeping instant coffee soluble Just pour hot water over a teaspoon of the brown granules and your coffee is ready. Consumers expect instant coffee to be perfectly granular and to dissolve easily in the cup. Storage without loss of quality and flavor is also a must. For a great coffee, the moisture content is key and determined at various steps of production. Moisture indicates the condition of coffee beans after shipment is important for the roaster and determines the optimal drying temperature for granulation into instant coffee.

Density & Refractive Index The Unique Cola Taste A Matter of Raw Material Testing Density and refractive index are important raw material checks in beverage production. Busy, central raw material laboratories analyze thousands of samples a year. Here we explain how the METTLER TOLEDO LIQC system substantially improves productivity and results quality. Beverage consumers expect their cola to taste the same, anywhere and at all times. To achieve this, leading beverage companies perform stringent raw material analysis in central laboratories on all ingredients used in plants all over the world. Density and refractive index are key The large numbers of ingredients along with large scale production result in a great number of samples to be analyzed. Some laboratories process more than 1000 samples per month. Density and refractive index measurement are key parameters for identification and specifications testing and have to be analyzed in almost every sample. The new METTLER TOLEDO LIQC measurement system allows both determinations to be carried out simultaneously, with a high degree of automation. LIQC for simple, complete automation The system consists of a round table SC30 sample changer with an integrated barcode reader, a combined density and refractive index instrument DR40 and the LIQC PC software with integrated data base functionality as well as flexible LIMS export possibilities. Thanks to bar code labeling, the LIQC system recognizes each sample, chooses the appropriate measurement method and performs the analyses. At the end, results are transferred into LIQC software, evaluated against specification limits and saved in a file format suitable for LIMS import. Substantial savings Potential savings are enormous. Compared to semi-automated instruments, LIQC saves up to 6 minutes of operating time per sample in sampling, cleaning and data entry. For a busy raw material laboratory this soon translates into savings of thousands of dollars and a very quick pay back indeed.

One Click Titration Titration in the Beverage Industry Simple Acid Content Determination with one Click Many medium size companies in the beverage industry have only one lab for the production and quality control area. Hence many different people with many different tasks work with the same instrument. This is where a user definable Home Screen with Short Cuts minimizes operating time and helps to avoid costly mistakes. Different processes need a flexible system The determination of the acid content is an important titration in the beverage industry and is often performed manually using a glass burette and color indicator. Acid content methods on automatic titrators often mimic the manual procedure to get comparable results. Often these oldfashioned methods are run besides other, more sophisticated procedures. To prevent errors, the right titrant, concentration and correct burette sizes have to be used with all the different methods. This becomes even more important if many different people work with the same instrument. titration methods. These can be started directly from the Home Screen with just one click on the Short Cut. In addition, the sophisticated plug and play system ensures for example that the burettes are recognized automatically via RFID and a method can only be started if the right titrant, with the right concentration and correct burette size is recognized on a drive. No need to restart or reconfigure the system. Parameters, such as titrant expiry date or electrode performance are checked the titration can be started automatically Tailored systems to reduce cost of operation Depending on individual needs, the Titration Excellence line together with the Rondo 60 or Rondolino sample changer offers a system, which reduces operating and training time.
