The thesis refers to the food (alcohol production) industry. This field produces vodka, fruit liqueurs, wines, punches, cream liqueurs, etc. Within recent years the alcohol production in Russian Federation has been decreasing. Thus, according to the data from Federal State Statistic Service the amount of vodka and liqueurs produced in 2006 in Russian Federation decreased by 9.6 % compared to 2005 and was equal to 120 mln decaliters. In 2007 only 96 % of the total 2006 volume was produced. As products of the industry have food applications, quality is of a great value. However, the production technology was formed more than a century ago and hasn‟t been significantly changed since then. The main problem in liqueurs production is inclination to clouding. Liqueurs are colloidal systems and hence are unstable while storage; very often indicative dimness and sediments are formed in them. This dimness doesn‟t satisfy any of existing regulations and the product should be then returned to the mill and reprocessed which leads to increased costs. Therefore, improving of the existing technology of liqueurs production is of current interest. With regard to vodka production, all the distilleries work on improving organoleptic properties of the product. Main areas of focus are multistage water purifying and flavor agents addition. However, according to our data only few experiments have been made on how the exothermal reaction of water-alcohol mixing impacts product‟s organoleptics. We think that research in this field may also have practical importance.
