The Influence of Enzymatic Treatment on the Process of Producing Alcoholized Fruit Drinks from Dried Raw Materials

Abstract

The traditional method of obtaining alcoholic drinks is a two-time infusion of crushed raw materials with water-alcohol liquid of different strength. The process of extraction of soluble substances is a long process: with a double infusion for dried raw materials, it is from 12 to 24 days. To speed up the process of extraction and more complete depletion of raw materials known bio-chemical method of pretreatment of fruit and berry raw materials. However, the effectiveness of bioconversion of dried fruit and berry raw materials has not been studied enough. The aim of the work is the selection of multi-enzyme compositions using drugs of different directions of action for the effective treatment of dried Rowan and prunes. The method of mathematical planning of the experiment selected multi-enzyme compositions of preparations pectolytic, cellulolytic and proteolytic action for pretreatment of dried Rowan and prunes before the infusion process. Enzymatic processing of dried rowan was carried out for 5 hours, prunes - for 2 hours at 40 °C, then ethyl rectified alcohol was added from the calculation of obtaining a strength of 50 % and the ratio of raw materials : extractant - 1:4, double insisting in the course of time is sufficient to achieve a dynamic equilibrium of the extractive substances in the solid and liquid phases, the morphs of the 1st and 2nd plums were drained and the physicochemical parameters of the fruit were determined (acidity, extractivity, total phenolic substances, speed of filtration, protein substances, color, transparency). The high efficiency of multi-enzyme compositions is noted. Bioconversion of dried raw materials allows to improve drainage properties of pulp, to increase the yield of fruit drinks with a higher content of extractives, more transparent at a filtration rate 1.7-2 times higher than in control. Improvement of technological parameters of fruit drinks will allow to receive easily filtered, transparent drinks with increase in terms of their stability at storage further.
