METHOD OF PRODUCING ETHYL ALCOHOL FROM TOPINAMBOUR Russian patent published in 2007 - IPC C12P7/00 

FIELD: ethyl alcohol production.

SUBSTANCE: topinambour is ground to form mixing, to which calcium sulfate is added along with multienzyme composition comprised of proteolytic and cytolytic enzymes in amounts 3.5-4.0 and 0.2-0.5 corresponding units per 1 g raw material, respectively. Mixing is hydrolyzed for 4-5 h to form non-clarified wort, which separated into clarified wort and solid residue. The latter is used in production of pectin products and the former is cooled, made aseptic, and fermented over a 24-36 h period. Resulting brew is separated into thin and thick fractions, the latter being used to produce yeast while the former is distilled to produce ethyl alcohol.

EFFECT: improved quality of product due to reduced level of harmful volatiles and intensified fermentation process thanks to increased topinambour hydrolysis degree and accumulation of important amounts of free sugars in clarified wort.
