Abstract
The present invention relates to a method of isolating proteins from a proteinaceous vegetable material. More specifically the invention provides a method for isolating proteins from a proteinaceous vegetable material, which method involves the steps of subjecting the proteinaceous vegetable material to the action of one or more carbohydrate degrading enzyme(s), thereby obtaining a mixture comprising proteins and hydrolyzed carbohydrates; and subjecting the mixture of step (i) to a separation process in order to separate the proteins from the hydrolyzed carbohydrates.

A method of preparing a soy protein isolate or concentrate from a proteinaceous soy material, said method comprising:
- (i) suspending the soy protein-containing material in an aqueous solution at a pH of above 7;
- (ii) subjecting the suspension obtained in (i) to the action of one or more carbohydrate degrading enzyme(s), thereby obtaining a mixture comprising proteins and hydrolyzed carbohydrates;
- and
- (iii) subjecting the mixture of step (ii) to a separation process comprising membrane filtration process in order to separate the proteins from the hydrolyzed carbohydrates to obtain as a product a soy protein isolate or concentrate.
A method of isolating proteins from a proteinaceous soy material, said method comprising:
- (i) suspending the material in an aqueous solution at a pH of above 7;
- (ii) subjecting the suspension obtained in (i) to the action of one or more carbohydrate degrading enzyme(s), thereby obtaining a mixture comprising proteins and hydrolyzed carbohydrates;
- and
- (iii) subjecting the mixture of step (ii) to a separation process in order to separate the proteins from the hydrolyzed carbohydrates to obtain a soy protein product, wherein the product comprises more than 80% by dry weight of soy protein.
