1 Snack Food Weighing and Analysis in the Laboratory 3 News Density and Refractive Index Ensures the Smooth Taste of Nutella Italian chocolate maker Ferrero is famous for many brand products. For example, Kinder chocolate and Nutella chocolate spread are well known. The METTLER TOLEDO combined density and refractive index instrument DR40 lies at the heart of quality control operations. Key parameters in quality control For their confectionary products, Ferrero uses many raw materials such as flavors, alcoholic liqueurs or fondants. Density and refractive index measurements allow quick and unambiguous product identification and serve to determine concentrations in binary or tertiary mixtures. Ferrero typically analyzes around ten samples per day and performs multiple measurements per sample. Numerous benefits for Ferrero Ferrero have combined density and refractive index determination with one instrument for added operator convenience and increased lab productivity. The DR40-SC1 automated system from METTLER TOLEDO eliminates fiddling with syringes and lengthy manual clean- ing operations. Instead, operators simply place the sample in a glass vial onto the SC1 sample delivery unit. The instrument pumps the sample into both measuring cells, adjusts the temperature to a set value, prints results to the attached printer and thoroughly cleans the measuring cell ready for the next sample. Leading brands manufacturers cannot compromise on product quality as brand assets are soon devalued by dissatisfied consumers. Ferrero maintains this paradigm by choosing a METTLER TOLEDO combined density and refractive index instrument. Besides optimizing product quality, they also believe that productivity is improved.

3 Moisture Analysis The Secret of Crispy French Fries an Optimal Moisture Content Nowadays, potatoes are consumed in many ways. In terms of popularity, French fries clearly are first choice. The Swiss company KADI knows all the secrets of manufacturing mouth-watering fries. Besides top quality ingredients and controlled processes, the right moisture content is key for perfectly golden and crispy fries a good reason for KADI to rely on METTLER TOLEDO moisture analyzers. The best French fries in town Deep-fried and golden brown is how everybody loves them. Most restaurants rely on frozen, pre-fried French fries for the sake of convenience and quality. A renowned, innovative producer of high quality French fries is the Swiss company KADI supplier of the KADI SUPER- FRITES. These French fries are not only super crisp, but also super profitable for the chef, thanks to a patented coating, the Knuspermantel. Selected raw materials, careful processing and continuous quality control are KADI s recipe for high quality fries. The Swiss company is BRC certified. Fast results for maximum crispness The process of turning potatoes into frozen French fries starts with washing, peeling and cutting. The potatoes then undergo various heat treatments including blanching, drying, pre-frying, cooling and freezing. For taste and texture of French fries the moisture content plays a crucial role and is analyzed at several points during processing. Quality manager Niklaus Meyer explains the importance of moisture analysis: Depending on the moisture content, the frying temperature is adjusted. Only optimized conditions give good quality fries. Potatoes containing excess moisture would absorb too much oil and come out soggy. At KADI the halogen technology of the HR83 moisture analyzer has been chosen to ensure the quality of its French fries. The HR83 moisture analyzer is fast, easy-to-use and reliably delivers our results, says Mr. Meyer, adding that an additional plus is METTLER TOLEDO s periodic on-site maintenance and calibration service. 3

4 Differential Scanning Calorimetry Liquid Fraction of Palm Oils Differential scanning calorimetry (DSC) is a powerful tool to characterize palm oil used in food products and for processing. The following example highlights how detailed information on crystallization and melting behavior can help maintain product quality. Palm oil and its liquid fraction, palm olein, are consumed in a wide variety of food products from instant noodles and crisps to cake mixes and snacks. The main supply of palm oil is from Malaysia with a production level around 50% of the global demand. The use of palm oil accounts for over 25% of the total global supply and demand in the oil market. Fruit of palm oil tree Fractionation of palm oil Fractionation is a physical process that uses the crystallization properties of triglycerides to separate a mixture into two or more fractions. The two fractions obtained from the fractionation of palm oil after crystallization at controlled temperatures are palm olein (liquid oil) and palm stearin (solid form). Palm oils of different origin and fractionated palm oils such as palm olein and palm stearin exhibit different melting and crystallization behavior. The results show that the DSC823 e can be used to characterize such oils and to obtain important information such as the liquid fraction at user-defined temperatures to guarantee and maintain optimal product quality. Palm oil is readily digested, absorbed and utilized in normal metabolic processes. Like other vegetable oils, it is cholesterolfree. Having a moderate level of saturation, it does not require hydrogenation for use as a fat component in foods and as such does not contain trans-fatty acids. The DSC heating curves shown in Figure 1 were measured using the DSC823 e and evaluated with the STAR e software. The liquid fraction was calculated by partial integration of the melting peaks. STAR e Figure 1: Liquide fraction of palm oil (Source: Collected Applications - Food) The results obtained are summarized in the table below: DSC823 e Liquid fraction of palm oil Sample Liquid raction at 25 C Temperature of last peak Palm olein 94.9 % 37.7 C Palm oil 79.8 % 40.7 C Palm stearin 53.1 % 53.7 C 4

5 One Click Titration Titration in the Snack Food Industry Acid and Chloride Determination in one Click Acids and chloride are essential ingredients in the snack food industry and have to be monitored continuously for a broad range of products. If these two measurements are combined in the same sample series the operator saves more than 50% of the time for sample preparation and instrument operation. Reduce your workload with combined analyses The quality of different products in the snack food industry such as vinegar chips, ketchup, pickles and many more is monitored for chloride concentration not only to get the right taste but also because of health issues. In addition the acid content is measured for some of the products. In the ideal world these two analyses could be combined to one and started with just one single click resulting in time savings of more than 50%. from unwanted changes and gives him the possibility to setup personalized Home Screens for each user. For repetitive tasks not only a single method but even sample series with combined titrations such as acid and chloride determinations can be saved as templates and linked to the Home Screen as Short Cuts. Once the user is logged in the only thing he has to do is to press the corresponding Short Cut and the whole analysis sequence is started with one single click. Combine One Click Titration with system automation The biggest benefit of the combination of these two determinations arises if the system is fully automated with a Rondo 60 sample changer. The only thing the operator has to take care of is to click the Short Cut and transfer sample identification and sample size to the system for example with a bar code reader. Increase lab capacity with just one click METTLER TOLEDO s new Titration Excellence line makes this dream come true. Titration analyses can be set up in methods with loops in a way that more than one task can be combined. First the acid content is determined and after a readjustment of the ph the chloride concentration can be determined. Thanks to the unsurpassed user guidance it is easy to develop such customized methods from preprogrammed METTLER TOLEDO methods. The user manager allows the lab manager to protect validated methods 5
