A process for producing a protein concentrate from oilseed from a plant of a family selected from the group consisting of Brassicaceae, Cannabaceae, Pedaliaceae, Rosaceae, and Fabaceae, preferably Brassicaceae. The method comprises the successive steps of:
a) providing a presscake from at least partially dehulled oilseed;
b) washing said presscake by mixing it with a first hydrous-alcohol solvent to obtain a washed presscake, and eventually separating said washed presscake from said first hydrous-alcohol solvent, to obtain a washed, an eventually separated, presscake, wherein said first hydrous-alcohol solvent has an alcohol concentration ranging from 60 % to 75% w/w; and
c) washing said washed, and eventually separated presscake by mixing it with a last hydrous-alcohol solvent to obtain a protein-containing solid and separating said protein-containing solid from said last hydrous-alcohol solvent to obtain a protein concentrate, wherein the alcohol concentration of the final hydrous-alcohol solvent is about the concentration of the azeotrope.
一种利用选自十字花科、大麻科、佩德利亚科、蔷薇科和豆科植物(最好是十字花科)的油籽生产浓缩蛋白的方法。该方法包括以下连续步骤
a) 从至少部分脱壳的油籽中提供榨饼;
b) 将所述压榨饼与第一水合醇溶剂混合进行洗涤,以获得洗涤后的压榨饼,并最终将所述洗涤后的压榨饼与所述第一水合醇溶剂分离,以获得洗涤后并最终分离的压榨饼,其中所述第一水合醇溶剂的醇浓度为 60% 至 75% w/w;以及
c) 通过与最后一种含水酒精溶剂混合来洗涤所述经洗涤并最终分离的压饼,以获得含蛋白质的固体,并从所述最后一种含水酒精溶剂中分离所述含蛋白质的固体,以获得蛋白质浓缩物,其中最后一种含水酒精溶剂的酒精浓度约为共沸物的浓度。
