FIELD: food industry.SUBSTANCE: method envisages raw material mixing with water at water duty equal to 1:(2.0-2.5), introduction of amylolytic enzyme preparations of diluent action in an amount of 0.5-1.0 units AS/g of reference starch, maintenance to produce a batch at a temperature of 65-70°C during 60 minutes with further maintenance at a temperature of 95-98°C during 60 minutes. Then the batch is cooled to 56-58°C, the amylolytic enzyme preparations of saccharifying action are introduced into the batch; final fermentative hydrolysis is performed during 30 minutes. The saccharified wort is cooled; a preparation of proteolytic action is introduced into the wort in an amount of 0.2-0.3 units PS/g of reference starch as well as seed yeast; the mixture is fermented during 48-54 hours. The raw material is represented by recyclable wastes of bakery production.EFFECT: invention allows to simplify the ethyl alcohol production method, intensify the fermentation process combined with preservation of high quality characteristics of the final product and its yield increase.2 tbl, 3 ex |
