Notes:
A novel process based on water leaching and ultrafiltration was developed for the production of rapeseed-protein products low in glucosinolates. The meal was contacted with water in two leaching stages, and the dissolved proteins were recovered in a two-stage ultrafiltration process. The first water extract was ultrafiltered and the retentate was diluted with the second extract, and then ultrafiltered again. Four ultratiltration membranes, with molecular weight cut-offs between 5000 and 100,000 daltons were tested. The process produced a meal, representing 75% of the feed weight, containing 0.2 mg/g of glucosinolates. A protein isolate, which contained 0.42 mg/g glucosinolates and 80.4% protein, represented a further 10% of the feed.
