OVERWIEW OF ALCOHOL PURIFICATION METHODS USED IN BEVERAGE INDUSTRY

摘要

The article gives overview of various methods of alcohol and alcoholic beverage producers to ensure the required quality of alcohol and its possible refinement. This applies especially for the removal of fermentation by-products and accompanying substances from alcohol, which are undesirable mainly from the sensorial point of view. In addition to repeated rectification and purification, the properties of alcohol can be improved by means of adsorption methods from which the adsorption of substances on activated carbon is the most frequently used one. There exists a number of alternatives and possibilities how to increase this process. For alcohol purification, some other filtration and adsorption materials can also be used, such as techniques based on the contact of alcohol with gas, additions of various agents or ion-exchange methods. These ways of treatment and purification of alcohol can be applied especially for the production of high-quality vodka brands.
