Enzymatic hydrolysis of starch and starch-containing plant raw material in obtaining sugar-containing products for animal husbandry (a review of patents)

The results of patent search on the subject of fermentative conversion and grain raw materials with technical solutions on fermentative conversion and starch-containing raw materials are given in the study. Patent researches were conducted on the depth of 24 years from 1994 to 2018. The conclu- sion about the relevance of this direction of the re-searches for animal husbandry was drawn. It was confirmed by growing number of granted patents for the inventions devoted to the development of methods of receiving grain hydrolyzates and feed molasses. All 17 inventions under consideration were aimed at improving the method of processing starch and starch-containing plant raw materials by enzymatic hydrolysis. The authors of the patents used starch, rye flour, rye grain, oats grain, barley grain, wheat grain as raw materials. For the imple- mentation of the method the following enzymes were used: glucoamylase, β-amylase, fungal α- amylase, bacterial α-amylase, xylanase, amilosubtilin, glucosamin, celloviridin, pullulanase, enzyme preparations - "Biobag", "BAN 480 L", "San Extra L", "Fungames BG", "Termamyl" and multienzyme compositions, mostly imported...
