摘要：
A novel canola protein isolate consisting predominantly of 2S canola proteinand having improved solubility properties, has an increased proportion of 2Scanola protein and a decreased proportion of 7S canola protein. The novelcanola protein isolate is formed by heat treatment of aqueous supernatant fromcanola protein micelle formation and precipitation, to effect precipitation of7S protein which is sedimented and removed. Alternatively, the novel canolaprotein isolate may be derived from a selective membrane procedure in which anaqueous canola protein solution containing 12S, 7S and 2S canola proteins issubjected to a first selective membrane technique to retain 12S and 7S canolaproteins in a retentate, which is dried to provide a canola protein isolateconsisting predominantly of 7S canola protein, and to permit 2S canola proteinto pass through the membrane, the permeate is subjected to a second selectivemembrane technique to retain 2S canola protein and to permit low molecularweight contaminants to pass through the membrane, and the retentate from thelatter membrane technique is dried.
