Abstract: A novel canola protein isolate consisting predominantly of 2S canola protein and having equal to better solubility properties and improved clarity properties, has an increased proportion of 2S canola protein and a decreased proportion of 7S canola protein. The novel canola protein isolate is formed by heat treatment or isoelectric precipitation of aqueous supernatant from canola protein micelle formation and precipitation, to effect precipitation of 7S protein which is sedimented and removed. Alternatively, the novel canola protein isolate may be derived from a selective membrane procedure in which an aqueous canola protein solution containing 12S, 7S and 2S canola proteins is subjected to a first selective membrane technique to retain 12S and 7S canola proteins in a retentate, which is dried to provide a canola protein isolate consisting predominantly of 7S canola protein, and to permit 2S canola protein to pass through the membrane.

Abstract: Soy protein products which can be reconstituted to provide an aqueous acidic solution having a preferred level of clarity are produced by extracting a soy protein source with an aqueous calcium chloride solution to cause solubilization of soy protein from the protein source and separating the resulting aqueous soy protein solution from residual soy protein source. Either, within about 20 minutes of separation step, the aqueous soy protein solution is diluted to a conductivity of less than about 90 mS and the pH of the aqueous soy protein solution is adjusted to about 1.5 to about 4.4 to produce an acidified soy protein solution having an absorbance of visible light at 600 nm (A600) of less than about 0.055, or, within about 40 minutes of the separation step, the aqueous soy protein solution is diluted to a conductivity of less than about 90 mS, the pH of the aqueous soy protein solution is adjusted to about 1.5 to about 4.

Abstract: A soy protein product having a protein content of at least about 60 wt % (N×6.25) d.b., preferably an isolate, is formed by a procedure in which soy protein is extracted from a soy source material using an aqueous calcium chloride solution at low pH, generally about 1.5 to about 5, and separating the resulting aqueous soy protein solution from residual soy protein source. The resulting clarified aqueous soy protein solution may be diluted and the pH adjusted within the range of 1.5-5.0. The solution may be concentrated by ultrafiltration, diafiltered and then dried to provide the soy protein product. The soy protein product is soluble in acidic medium and produces transparent, heat stable solutions and hence may be used for protein fortification of soft drinks and sports drinks.
