Abstract (en)
[origin: WO2018007491A1] 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.
