Abstract: Canola protein isolates are provided which contain both albumin and globulin protein fractions that are soluble, transparent and heat stable in an acidic aqueous environment. The canola protein isolates are completely soluble in water at low pH, low in phytic acid and useful in products for human consumption, pet foods and aquaculture.

Abstract: A soy protein product, which may be an isolate, produces transparent heat-stable solutions at low pH values and is useful for the fortification of soft drinks and sports drinks without precipitation of protein. The soy protein product is obtained by extracting a soy protein source material with an aqueous calcium salt solution to form an aqueous soy protein solution, separating the aqueous soy protein solution from residual soy protein source, adjusting the pH of the aqueous soy protein solution to a pH of about 1.5 to about 4.4 to produce an acidified clear soy protein solution, which may be dried, following optional concentration and diafiltration, to provide the soy protein product.

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.

Abstract: In the recovery of canola protein isolates from canola oil seeds steps are taken to inhibit the formation of colouring components and to reduce the presence of materials tending to form colouring components, to obtain a lighter and less yellow canola protein isolate.

Abstract: A novel canola protein isolate of predominantly 2S canola protein and having improved solubility 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 of aqueous supernatant from canola protein micelle formation and precipitation, to effect precipitation of 7S protein which is sedimented and removed.

Abstract: A soy protein product having a protein content of at least about 60 wt % (N×6.25) d.b., preferably at least about 90 wt %, and being completely soluble at pH values of less than about 4.4 and heat stable at such pH values is used to provide, at least in part, the protein component of a dairy analogue or plant/dairy blend frozen dessert mix.

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.
