Abstract: A soy protein product having a protein content of at least about 60 wt % (N×6.25) d.b., preferably an isolate having a protein content of at least about 90 wt % (N×6.25) d.b., is formed by extracting a soy protein source with water to form an aqueous protein solution having a pH of about 1.5 to about 11, preferably about 5 to about 7, and separating the resulting aqueous protein solution from residual soy protein source. The protein concentration of the aqueous protein solution is increased to about 50 to about 400 g/L while the ionic strength is maintained substantially constant by using a selective membrane technique. The resulting concentrated protein solution is optionally diafiltered and a calcium salt, preferably calcium chloride, is added to the concentrated and optionally diafiltered protein solution to a conductivity of 5 to about 30 mS.

The supernatant from the coalesced protein micellar mass may be processed to recover additional quantities of soy protein product. The soy protein product may be used for a fortification of soft drinks and sports drinks.

Abstract: A soy protein product which is completely soluble and is capable of providing transparent and heat stable solutions at low and neutral pH values is produced by extracting a soy protein source material with water at low pH, subjecting the resulting aqueous soy protein solution to ultrafiltration and optional diafiltration to provide a concentrated and optionally diafiltered soy protein solution, which may be dried to provide the soy protein product. The soy protein product may be used for protein fortification of, in particular, soft drinks and sports drinks, without precipitation of protein.

Abstract: A soy protein product having a protein content of at least 60 wt % (N×6.25) d.b., preferably an isolate having a protein content of at least about 90 wt % (N×6.25) d.b., is formed from the supernatant from the precipitation of a soy protein micellar mass. A calcium salt or other divalent salt is added to the supernatant, before concentration, after initial concentration or after final concentration, to provide a conductivity of about 2 to about 30 mS. Precipitate is removed from the resulting solution and the pH of the clear soy protein solution is optionally adjusted to about 1.5 to about 4.4. The optionally pH-adjusted clear solution is concentrated to a concentration of about 50 to about 400 g/L and the clear concentrated protein solution is optionally diafiltered prior to drying. The soy protein product is soluble in acidic media and produces transparent, heat stable solutions at low pH values and, therefore, may be used for protein fortification of soft drinks and sports drinks.

Abstract: Substantially pure 2S canola protein is obtained substantially free from 7S and 12S canola protein by a procedure in which 2S canola protein is captured by binding to a cation-exchange medium while permitting other proteins and impurities to be washed away. The 2S canola protein then is removed from the cation-exchange medium by exposure of the cation-exchange medium to saline at a suitably high salt concentration.
