Food and Beverages – the Energy Supplier for Your Brain
Dextrose is the most important fuel for our cells. It serves our body as an energy supplier. The biggest consumer is our brain. Dextrose is also hidden in lactose, table sugar, and starch. With an energy requirement of 2,000 kcal per day, foods with a total of 264 g carbohydrates (a group that includes sugar and starch), 66 g fat, and 72 g protein should be consumed.* LANXESS Lewatit® ion exchange resins play an important role in the production of food ingredients like carbohydrates and proteins. The refining steps with our Lewatit® ion exchange resins include demineralization, decolorization, and separation.
Lewatit® ion exchange resins are an established and indis pensable component in the food and beverage industry. Lewatit® S resins are certified in many countries around the world for the processing of food, beverages, and food and drink additives. The Lewatit® S series has, among other things, halal and kosher certifications.
Lewatit® ion exchangers and adsorbers play a crucial role in separation processes. Often there is no alternative to isolat ing, enriching, and cleaning valuable materials from the liquid phase.
An important application in the food industry is the process ing of sugar. The largescale production of crystal and liquid sugar, which is widely used in the food and beverage industry, would hardly be economically feasible without macroporous Lewatit® S types. The resins are used in the purification of raw sugar of various qualities. In addition to salt ions, they remove the yellowishbrown components that give raw sugar its color and typical taste.
Another important area of application for Lewatit® S grades is the starch industry. This produces highquality syrups and polyalcohols on the basis of starch hydrolysates for use as sweeteners, e.g., in soft drinks. We offer a large number of special ion exchangers for the desalination and decoloring (refining) of these syrups.
The LewaPlus® FD module, within the Lewaplus® design software, is a tool for optimizing processes in the food and beverage processing industry to maximize productivity and at the same time to save resources. With the aim of creat ing sustainable processes, LewaPlus® also helps to calculate ideal system configurations for new systems.
Our ion exchangers also play a decisive role in ensuring product quality in other areas of the food and beverage industry. These include the processing of fruit juices, gelatin, whey, wine, and pectin.
