摘要：
The present invention is directed to a native rapeseed protein isolate comprising 40 to 65 wt.% cruciferins and 35 to 60 wt.% napins and having a solubility of at least 88% over a pH range from 3 to 10 at a temperature of 23±2°C with a microbe level of less than 1,000 CFU/g. The use of the native rapeseed protein isolate in food products or pet food products is claimed. A process for obtaining a native rapeseed protein isolate comprising the following steps is also claimed: 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 step i) iii) decreaming of the aqueous liquid obtained in step ii) iv) adjusting the pH of the decreamed aqueous liquid obtained in step iii) to neutral by adding acid or base, and mixing with a precipitant to obtain a precipitate v) removing the precipitate obtained in step iv) to obtain an aqueous liquid vi) concentrating and washing the aqueous liquid obtained in step v) vii) isolating native rapeseed protein isolate from the concentrated and washed aqueous liquid obtained in step vi) by means of drying.
