METHODS OF FERMENTATION OF CARBOHYDRATE-RICH AGRICULTURAL CROPS Russian patent published in 2018 - IPC C12P7/06 

FIELD: agriculture.

SUBSTANCE: method involves providing a carbohydrate-rich parenchyma tissue of a plant containing an apoplast at an agricultural crop temperature of 5 to 40°C. The said parenchyma tissue of the plant is combined with an aqueous solution containing yeast at a solution temperature of from 20 to 40°C. The said parenchymal plant tissue is influenced by the pressure of gaseous phase during preparation during the preparation time, or before the plant tissue is combined with the aqueous solution containing yeast, or after said combination. Wherein, the specified time of preparation varies from 1 minute up to 1 hour, but the pressure of gaseous phase in the preparation is less than the atmospheric pressure and ranges from 105 to 200% of the equilibrium vapour pressure at higher temperatures from the specified temperature of crop and the specified solution temperature. The said parenchymal plant tissue is influenced by the pressure of gaseous phase during infusions over time of infusions of from 1 minute up to 1 hour, where the specified yeast are infused into specified apoplast and where the specified pressure of gaseous phase at infusion is more than specified pressure of gaseous phase in the preparation. Free fluid is diverted, that was not drawn into the apoplast, then the pressure of the gaseous phase is supported at fermentation during fermentation time to obtain products of fermentation within the specified apoplast without re-entering the specified water solution containing yeast, in the specified parenchymal plant tissue. Wherein, the specified pressure of gaseous phase at a fermentation is greater than the specified pressure of gaseous phase at the preparation, specified fermentation time is from 6 hours up to 7 days, and the fermentation products are obtained by fermentation of carbohydrates, selected from a group consisting of simple sugars simple sugars obtained by hydrolysis of starch, and their combinations, and where carbon dioxide does not displace specified yeast from the specified apoplast during the fermentation.

EFFECT: invention provides efficient fermentation of carbohydrate-rich crops.
