PROCESSING OF BIOMASS Russian patent published in 2017 - IPC C13K1/02 C13K13/00 C08B1/00 A23K10/30 A23K10/32 A23K10/33 B01J19/08 

FIELD: biotechnology.

SUBSTANCE: provides a method for increasing the availability of carbohydrates in the biomass feedstock. By cutting, grinding, crushing, grinding or chopping reduce the size of the original biomass material containing polysaccharides selected from cellulose, pectin, hemicellulose, and mixtures thereof. Initial biomass, containing less than 5% of water, is obtained. Initial biomass is irradiated by electron beam at a dose level of 1 to 10 Mrad/s and a power of 1 kW to 500 to produce a first processed biomass material. And then it is cooled and again, the treated first biomass material is irradited with an electron beam at a dose level of 1 to 10 Mrad/s and a power of 1 kW to 500 kW. The second processed biomass material is obtained having a number of average molecular weight from 3000 to 50,000 daltons of carbohydrates and increased accessibility.

EFFECT: invention allows to obtain a material having a nutrient availability greater than the nutrient availability of the biomass of the original.
