Publication number: 20200015496Abstract: The invention relates to a method of processing a pulse protein material, which comprises effecting hydrolysis of the pulse protein material, optionally adjusting the pH, then separating to form a soluble fraction and processing the soluble fraction to provide a pulse protein hydrolyzate which is substantially completely soluble throughout the pH range of about 2 to about 7 and which provides little or no astringency when an acidic beverage containing the pulse protein hydrolyzate is consumed and a solid residue, and processing the solid residue to provide a second pulse protein hydrolyzate having an improved Amino Acid Score, which is improved compared to the substrate pulse protein material.Type: ApplicationFiled: March 5, 2018Publication date: January 16, 2020Applicant: Burcon NutraScience (MB) Corp.Inventors: Martin SCHWEIZER, Brandy GOSNELL, Randy WILLARDSEN, Sarah MEDINA, Kevin SEGALL

Patent number: 9011959Abstract: 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.Type: GrantFiled: April 2, 2013Date of Patent: April 21, 2015Assignee: Burcon Nutrascience (MB) Corp.Inventors: Martin Schweizer, Brent E.

Publication number: 20140066597Abstract: A canola protein isolate useful in aquaculture is formed by a procedure in which canola oil seed meal is extracted to cause solubilization of protein in the canola oil seed meal to form an aqueous protein solution having a protein content of about 5 to about 40 g/L and a pH of about 5 to about 6.8. After separation of the aqueous protein solution from the residual canola oil seed meal, the protein concentration is increased to at least about 50 g/L while maintaining the ionic strength substantially constant by using a selective membrane technique. The concentrated protein solution is dried to provide a canola protein isolate having a protein content of at least about 90 wt % (N×6.25) d.b.Type: ApplicationFiled: September 10, 2013Publication date: March 6, 2014Inventors: Martin Schweizer, Brent E.
