Claim 0:
1. A process for obtaining a native rapeseed protein isolate comprising:
i) mixing cold-pressed rapeseed oil meal with an aqueous liquid at a temperature of from 45 to 65° C.;
ii) separation of the aqueous liquid from the mixture obtained in i);
iii) decreaming of the aqueous liquid obtained in ii) by centrifugation or filtration;
iv) adjusting the pH of the decreamed aqueous liquid obtained in iii) to neutral by adding acid in the presence of a precipitant to obtain a precipitate;
v) removing the precipitate obtained in iv) to obtain an aqueous liquid;
vi) concentrating and washing the aqueous liquid obtained in v);
vii) isolating native rapeseed protein isolate from the concentrated and washed aqueous liquid obtained in vi) by means of drying,, wherein said rapeseed protein isolate comprises 40 to 65% of cruciferins and 35 to 60% of napins and wherein said rapeseed protein isolate has a solubility of at least 88% in water when measured over a pH range from 3 to 10 at a temperature of 23±2° C.
