Patent number: 7794762Abstract: Oil seed protein isolates, particularly canola protein isolate, are produced at a high purity level of at least about 100 wt % (N×6.25) by a process wherein oil seed protein is extracted from oil seed meal, the resulting aqueous protein solution is concentrated to a protein content of at least about 200 g/L, and the concentrated protein solution is added to chilled water having a temperature below about 15° C. to form protein micelles, which are settled to provide a protein micellar mass (PMM). The protein micellar mass is separated from supernatant and may be dried. The supernatant may be processed to recover additional oil seed protein isolate by concentrating the supernatant and then drying the concentrated supernatant, to produce a protein isolate having a protein content of at least about 90 wt %. The concentrated supernatant may be mixed in varying proportions with at least part of the PMM and the mixture dried to produce a protein isolate having a protein content of at least about 90 wt %.Type: GrantFiled: March 23, 2005Date of Patent: September 14, 2010Assignee: Burcon NutraScience (MB) Corp.Inventors: Larry D.

Patent number: 7750119Abstract: 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.

Patent number: 7704534Abstract: Oil seed protein isolates, particularly canola protein isolate, are produced continuously from oil seed meals, preferably at a high purity level of at least about 100 wt % (Nx 6.25), by a process wherein oil seed protein is continuously extracted from oil seed meal, the resulting protein solution is continuously concentrated, preferably to a protein content of at least about 200 g/L, and the concentrated protein solution is continuously mixed with chilled water having a temperature below about 15° C. to form protein micellar, which are settled in the settling vessel to provide a protein micellar mass (PMM) while supernatant overflows the vessel.
