    摘要: 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 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. Alternatively, the concentrated and optionally diafiltered soy protein solution may be optionally adjusted in pH within the range of 1.5-7.0 then diluted into water to cause the formation of a precipitate, separating the precipitate from the diluting water (supernatant) and drying the separated soy protein to form a soy protein product having a protein content of at least about 60 wt % (N×6.25) d.b., preferably a soy protein isolate having a protein content of at least about 90 wt % (N×6.25) d.b. The supernatant may be processed to form soy protein products having a protein content of at least about 60 wt % (N×6.25) d.b., preferably a soy protein isolate having a protein content of at least 90 wt % (N×6.25) d.b. Alternatively, the precipitate from the dilution step may be re-solubilized in the diluting water by adjustment of the pH to resolubilize the precipitate and form a protein solution. The soy protein solution may be concentrated while maintaining the ionic strength substantially constant by using a selective membrane technique followed by optional diafiltration and drying. 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.

    摘要: A soluble canola protein isolate is prepared from canola protein micellar mass by solubilizing the protein micellar mass in a calcium salt solution, preferably a calcium chloride solution, followed by dilution of the resulting canola protein solution. Following removal of the precipitate phytic acid, the aqueous canola protein solution is concentrated, optionally diafiltered, and acidified to a pH of about 2.5 to 4.0 to produce an acidified clear canola protein solution, which may be concentrated, subjected to a color removal step and dried. The canola protein isolate so formed is soluble, transparent and heat stable in an acid aqueous environment and also is soluble at natural pH, without precipitation of protein.

    摘要: A novel canola protein isolate made 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. The permeate is subjected to a second selective membrane technique to retain 2S canola protein and to permit low molecular weight contaminants to pass through the membrane, and the retentate from the latter membrane technique is dried.

    摘要: 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 4.4, the acidified soy protein solution is heat treated at a temperature of about 70° to about 160° C. for about 10 seconds to about 60 minutes to produce an acidified soy protein solution having an absorbance of visible light at 600 nm (A600) of less than about 0.055. The resulting acidified soy protein solution may be directly dried or further processed by concentration and diafiltration. Each of the steps of the process preferably is effected at a temperature of about 50° to about 60° C.
