The efficiency of using new brands silica gel for colloidal stabilization of beer

Бесплатный доступ

The production of beer that meets the requirements of consumers in terms of quality and price is one of the most important aspects of competition in their sales market. It is known that the quality of the beer is associated with colloidal stability, which is often achieved through the use of different methods, such as chemical, enzymatic and physicochemical methods. Chemical methods are used to reduce the rate of oxidative processes in beer by introducing antioxidants. At the same time, enzymatic methods are often used in the mashing step. They involve enzyme preparations to regulate the levels of protein and carbohydrates (?-glucans and dextrins) in the beer. In breweries, physicochemical methods based on adsorbents that help remove major haze components such as protein and polyphenols from beer are commonly used. Since expensive imported materials such as silica gel and PVPP are widely used in Russia, which leads to additional production costs, this work is devoted to studying the possibility of reducing the costs of beer stabilization by replacing imported silica gels with domestic ones. For the study, we used domestic silica gels manufactured by "Tovesorb" (Russia). In addition, we used silica gels of foreign production Stabifix (Germany) and Britesorb L10 (Netherlands) as a control. The obtained results showed the prospects of using domestic brands of silica gel from "Tovesorb" (Russia), which were not inferior to imported analogues in terms of their adsorption properties.
