PROTEIN FOOD INGREDIENT (VARIANTS) Russian patent published in 2004 - IPC

FIELD: food industry. SUBSTANCE: by one variant, unpurified soybean protein material of functional food ingredient has got nitrogen index of solubility being about 30-80% and, at least, one of the following characteristics: index of resistance towards salt, hydration capacity by water, viscosity. By another variant, unpurified soybean protein material of functional food ingredient has, at least, one of the following characteristics: the weight of aqueous suspension's gel or the strength of cooled gel. Protein food ingredient is obtained due to hydration of either granulated or freeflowing unpurified soybean protein material. The present innovation enables to obtain unpurified soybean protein material at low content of oligosaccharides of raffinose and stachyose, but without high price for processing. EFFECT: higher efficiency. 11 cl, 15 ex, 12 tbl
