METHOD OF PRODUCING ETHYL ALCOHOL Russian patent published in 2018 - IPC C12P7/06 

FIELD: biochemistry.

SUBSTANCE: method involves preparing a batch of crushed orzo grain, water in a ratio of 1:3 and a complex of enzymes, including a source of α-amylase – Liquoflow, source of protease – Prolyve BS Liquide and a complex preparation of cellulase, xylanase and β-glucanase – Viscostar 150L. Enzymatic heat treatment of the batch is carried out in three stages. Then the resulting mass is cooled to a temperature of 57–58°C and saccharified with Glucoside 500L enzyme preparation of glucoamylase. Resulting wort is cooled and fermented for 55–60 hours, from the produced mash, ethyl alcohol is isolated by distillation.

EFFECT: proposed method makes it possible to increase the yield of ethyl alcohol by using non-starch polysaccharides and orzo grain proteins, reduce the viscosity of batch, the duration of enzymatic heat treatment and the fermentation process.
