Abstract
The present invention relates to a process of extracting native proteins from vegetable source materials such as oil-seeds, legumes and grains. Native proteins mentioned in this invention are present in the source material in their non-denatured state, i.e. with their functional properties relevant to application in food industry like solubility preserved and not compromised by processing conditions. Source materials mentioned in the present invention are of vegetable origin and typically contain significant (>5% by weight) amounts of native oils and lipids. The invention further relates to a device for carrying out this process and to the native protein obtainable by the process of the invention.

A process for the preparation of a protein extract from meal or oil cake of oil seeds, the process comprising:
- (a) preparing in a container a mixture of an aqueous solution and comminuted meal or oil cake from oil seeds, wherein the comminuted particles have an average particle size (d32) smaller than 1000 μm;
- (b) creating a fluidized bed of the comminuted meal or oil cake particles in the container by flow generation means provided in the container and letting at least a part of the proteins present in the comminuted meal or oil cake dissolve into the aqueous solution;
- (c) separating under fluidized bed conditions at least a part of the dissolved protein from the mixture by filtration means provided in the container, such that a protein extract is obtained.
