PRODUCTION OF PROTEIN PRODUCTS FROM BEANS ("YP810") Russian patent published in 2020 - IPC A23J1/14 A23J3/14 

FIELD: food industry.

SUBSTANCE: to produce a protein product of legumes with protein content of at least about 60–90 wt % (N×6.25) based on dry substance, method is carried out as follows. Extracting source of protein from legumes to solubilise protein and to produce aqueous solution of protein, where pH ranges from 6 to 11. At least partial separation of aqueous protein solution from residual protein source is performed. PH of the aqueous protein solution is adjusted to pH approximately 1.5 to 3.4. Solid acid-insoluble material is separated from acidified protein solution. Concentrate, diafilter and dry the protein solution if necessary. Or one concentrates and/or diafiltered solution for fractionation of the protein component onto the first concentrate and the first permeate. First concentrate is dried to produce the first protein product. First permeate is concentrated and if necessary diafiltrated to obtain a second concentrate and a second permeate. Second concentrate is dried to produce a second protein product.

EFFECT: invention ensures production of a product with very low or substantially absent pea-and-vegetable taste-and-flavor notes, which does not include use of calcium salt or other salt during protein extraction.
