  • 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.

  • Publication number: 20140288780
    Abstract: A method for checking a sensor signal suitable for actuating a passenger protection arrangement of a vehicle. The method includes a step of carrying out a comparison between the sensor signal and at least one reference signal, repeatedly within a predetermined time interval, in order to obtain a plurality of comparison results, and a step of evaluating the sensor signal based on the plurality of comparison results, in order to detect a fault in the sensor signal.

  • Publication number: 20140256914
    Abstract: A pulse protein product having a protein content of at least about 50 wt % (N×6.25) d.b. is recovered in the processing of pulse protein source material to form pulse protein products wherein the pulse protein source is extracted in one embodiment with calcium salt solution. The resulting pulse protein solution is separated from the bulk of the residual pulse protein source and then the pulse protein solution is processed to remove finer residual solids, which are optionally washed and then dried to provide the pulse protein product. In another embodiment, the pulse protein source is extracted with water, the bulk of the residual protein source removed and the resulting pulse protein solution treated with calcium salt to precipitate phytic acid. The precipitated phytic acid and any finer residual solids remaining in solution after the initial separation step are removed from the pulse protein solution then optionally washed and dried to provide the pulse protein product.
