摘要：
1. A method of producing a canola protein isolate having a protein content of at least about 90 wt.% (N × 6.25), calculated on a dry weight basis, comprising:! (a) optionally (i) partial concentration of the supernatant from precipitation of the micellar mass of the canola protein to a concentration of 50 g / l or less, or! (ii) concentrating the supernatant from precipitating the micellar mass of the canola protein to a concentration of at least 50 g / l； ! (bI) adding a calcium salt； ! (i) to the supernatant from precipitation of the canola protein micellar mass in the absence of an optional step (a) to ensure electrical conductivity of 5 to 30 mS (millisiemens, ms) with the formation of a precipitate of calcium phytate, or! (ii) to a partially concentrated supernatant or concentrated supernatant in the presence of an optional step (a) to ensure electrical conductivity of 2 to 30 mS with the formation of calcium phytate precipitate,! (ii) removing a precipitate of calcium phytate from the general solution to obtain a clear solution,! (iii) optionally setting the pH of the clear solution at a pH of 2.0 to 4.0 to obtain a clear solution with a pH adjusted, and! (iv) in the absence of optional step (aii) or in the presence of step (ai) by concentrating a clear solution with an optional pH adjusted to a concentration of at least 50 g / l to obtain a clear concentrated canola protein solution, or! (bII) (i) adding an initial amount of calcium salt to the supernatant from precipitation of the canola protein micellar mass to provide electrical conductivity from 1 to 3.5 mS, which is insufficient to initiate precipitation of calcium phytate,! (ii) setting the pH of the total solution at a pH level from1.
