摘要：
1. A method of obtaining a canola protein isolate having a canola protein content of at least 90 wt.% (N · 6.25) d.b. (in terms of dry weight), including:! (a) extracting flour from canola oil seed at a temperature of at least 5 ° C so as to initiate solubilization of canola protein from flour and the formation of an aqueous protein solution having a protein content of from 5 to 40 g / l and a pH of from 5 to 6.8,! (b) separating the aqueous protein solution from the spent oilseed meal,! (ci) increasing the concentration of the aqueous protein solution to 50-250 g / l while maintaining the ionic strength of the solution substantially constant using selective membrane technology to produce the first concentrated protein solution,! (di) optionally diafiltration of the first concentrated protein solution,! (ei) adding a calcium salt solution to the first concentrated and optionally diafiltered protein solution to a solution conductivity of 15 to 25 mS (millisiemens, mSm) so as to precipitate in the first concentrated protein solution, and! (fi) removing the precipitate from the first concentrated protein solution or! (cii) adding a calcium salt solution to an aqueous protein solution to an electrical conductivity of 15 to 25 mS in order to cause precipitation in the concentrated protein solution,! (dii) removing the precipitate from the canola protein solution,! (eii) increasing the protein concentration in an aqueous protein solution to 50-250 g / l while maintaining the ionic strength of the solution substantially constant using selective membrane technology to produce the first concentrated protein p1. Способ получения изолята белка канолы, имеющего содержание белка канолы, по меньшей мере, 90 мас.% (N·6,25) d.b. (в пересчете на сухую массу), включающий: ! (a) экстракцию муки из масличных семян канолы при температуре, по меньшей мере, 5°С с тем, чтобы инициировать солюбилизацию белка канолы из муки и образование водного белкового раствора, имеющего содержание белка
