TH121110B - Production of soluble soy protein products from the micellar mass of soy protein ("S200Ca") - Google Patents

Abstract

Soy protein products with at least 60% protein content by weight (N x 6.25) by dry weight, desirable are Isoloate with protein content At least approximately 90% by weight (N x 2.5) by dry weight Was made up of clear water from Precipitation of the micellar mass, calcium salt or other divalent salt was added to the clear water portion, before the concentration, after the periodic concentration. Start or after final concentration, to induce a conduction (conductivity) of approximately 2 to approximately 30 mS, the sediment was removed from the resulting solution and the pH of the protein solution from The clear soybeans were alternately adjusted to approximately 1.5 to 4.4. The optional pH-adjusted clear solution was concentrated to a concentration of approximately 50 to approximately 400 g / l and the clear protein concentrate was filtered. An alternative (diafilterd) pre-drying soy protein product is soluble in acidic media and produces a clear, thermally stable solution at low pH and therefore may be used for Protein supplement In soft drinks and sports drinks
