he improvement of technologies for the production of foodstuffs and dietary supplements from vegetable feedstock using natural and efficient biocatalytic systems is a promising direction in the development of agroindustrial complex. At present, enzyme preparations produced in Russia are virtually absent at the market; therewith, high cost of their imported analogs increases the prime cost of products. A study on efficiency of the domestic broad-spectrum enzyme preparation Glucanofoetidin, which was developed at the Russian Scientific Research Institute of Food Biotechnology, toward fruit and berry feedstock and corn showed an increase in the yield of extractive substances (amino acids, sugars, phenol compounds, and carotenoids), particularly the biologically active components (tocopherols, anthocyanins, and vitamins), by 7–18 % as well as the quality improvement and an increase in the yield of target products (juices and extracts) by 10–44 %. Practical importance of Glucanofoetidin consists in a more rational use of vegetable feedstock as compared to conventional technology without enzymatic treatment, and also in a considerable (twofold) shortening of the process time. The multienzyme composition of Glucanofoetidin makes it promising for use in juice, confectionary, brewing, oil-and-fat and baking industries.
