Abstract
Food grade protein and dietary fibre concentrates are prepared from wheat millfeed. The process utilizes an efficient alkali extraction to obtain in excess of 75% w/w of the protein present in the millfeed in a solution which is further treated to separate the suspended starch and fat. The clarified liquid containing the protein is passed over a semipermeable membrane during which it is further purified and concentrated. Hydrogen peroxide and heat are introduced to the liquid thereby reducing its color prior to spray drying. The resulting residue from the extraction is dried or further treated with hydrogen peroxide and heat to produce a light colored dietary fibre concentrate.
