Food and Beverages – the Energy Supplier for Your Brain

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.
