SOYA BEAN PRODUCT MANUFACTURE BY WAY OF WATER EXTRACTION ("S803") Russian patent published in 2015 - IPC A23J3/16 A23J1/14 A23L1/305 

FIELD: food industry.

SUBSTANCE: inventions group relates to food industry. The method for manufacture of a soya bean protein product, containing soya bean protein in an amount of at least 60 wt % (N×6.25) in conversion to dry weight, involves a soya bean protein source extraction with water with pH value equal to 1.5-3.6 with dissolution of soya bean protein from the protein source and with formation of soya bean protein water solution, soya bean protein water solution separation from the remaining soya bean protein source, soya bean water solution concentration in a selective membrane way, optionally- diafiltration of the concentrated soya bean protein solution and soya bean protein solution drying. The soya bean protein product is mixed with water-soluble powder materials for obtainment of the mixture water solutions where the mixture is preferably represented by powder beverage. The obtained soya bean protein product, preferably, beverage may be represented by acid solution or neutral solution with the soya bean protein product dissolved therein.

EFFECT: invention group allows to obtain a product without usage of calcium chloride dissolved with pH acidic values and pH value equal to 7 with formation of the product solution transparent and resistant to high temperature action; the product is intended for beverages enrichment with protein without protein sedimentation and without bean savour.
