Plant protein and its method of preparation

Abstract

The invention relates to a plant protein isolate containing less than 10 microgram, preferably less than 5 microgram, of the sum of hexanal, 2-pentyl-furan, (E)-2,4,heptadienal and 1-octen-3-ol per gram of dry matter and its method of preparation. The plant protein is preferably obtained from leguminous plant, more preferably from pea or fava bean, most preferably from pea. The method for extracting the plant protein isolate consists of the steps: (a) providing a protein containing seed, (b) milling said seed, (c) suspending the milled seed in water, (d) extracting proteins from said milled suspension and (e) washing the extracted proteins with water at a temperature between 60° C. and 100° C. and at a pH in the range of 4 to 5.5.
