Title: SWEET RAPESEED PROTEIN ISOLATE AND PROCESS FOR OBTAINING IT
Abstract:
The present invention describes a native rapeseed protein isolate which has a sweetness equivalent to at least 5 g/l of an aqueous sucrose solution when provided as a 2 wt.% aqueous solution. The rapeseed protein isolate preferably comprises 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. The use and food or beverage products are also claimed. The process for obtaining said native rapeseed protein isolate comprises the steps of: 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.
