METHOD OF PRODUCING PLANT PROTEIN CONCENTRATE FROM RAW SOYA MATERIAL Russian patent published in 2002 - IPC

FIELD: food-processing industry. SUBSTANCE: method involves grinding plant cake; preparing cake aqueous solution by using magnetized water at temperature of 61-65 C, hydromodulus of 1:11 - 1:20 and pH=4.7-4.8 for 40 min while periodically mixing; providing centrifuging and separating liquid phase from sediment; washing resultant sediment with water having temperature of 61-65 C and used in triple amount with regard to weight of sediment for 10 min while providing continuous mixing; separating liquid and solid phases by centrifuging; directing liquid phase for recovery and preparing new portion of suspension; subjecting solid phase to homogenization while mixing it with fresh portion of water used in double amount by weight and temperature of 30-40 C until homogeneous consistence is reached; neutralizing homogenate; heating liquid concentrate to 55-65 C upon neutralization; holding for one hour and providing dispersion drying. Method allows dry finely dispersed powder of yellowish or light-brown color to be produced. Powder comprises substantially all aminoacids needed for organism's activity, as well as set of irreplaceable aminoacids for use in dietary foods. EFFECT: increased yield of protein, improved functional properties and increased efficiency of method. 4 cl, 3 tbl
