  • Publication number: 20150173395
    Abstract: A hemp protein product, which may be an isolate, produces solutions at low pH values and is useful for the fortification of soft drinks and sports drinks without precipitation of protein. The hemp protein product is obtained by extracting a hemp protein source material with an aqueous calcium salt solution to form an aqueous hemp protein solution, separating the aqueous hemp protein solution from residual hemp protein source, adjusting the pH of the aqueous hemp protein solution to a pH of about 1.5 to about 4.4 to produce an acidified hemp protein solution, which may be dried, following optional concentration and diafiltration, to provide the hemp protein product.

  • Patent number: 9011959
    Abstract: 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.

  • Patent number: 8936824
    Abstract: 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 extracting a soy protein source with a salt solution, preferably aqueous sodium chloride solution, to form an aqueous protein solution having a pH of about 1.5 to 11, preferably about 5 to about 7 and separating the resulting aqueous protein solution from residual soy protein source. The protein concentration of the aqueous protein solution is increased to about 50 to about 400 g/L while the ionic strength is maintained substantially constant by using a selective membrane technique. The resulting concentrated protein solution is optionally diafiltered and a calcium salt, preferably calcium chloride, is added to the concentrated and optionally diafiltered protein solution to a conductivity of 15 to about 85 mS.

  • Patent number: 8741356
    Abstract: 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 %.
