Abstract:
1. A water dispersible protein product, comprising; a soy protein-containing material containing from about 65.0 wt. % to about 90.0 protein, characterized in that greater than 10.0 wt. % of same is retained by a U.S. Sieve No. 100 (150 micron diameter) mesh screen, wherein at least a portion of the protein therein is water soluble; a fluidized soy lecithin surfactant; and a flow agent, where said flow agent comprises precipitated amorphous silica having a particle size between 7 μm and 100 μm; wherein the soy protein-containing material is prepared by a method comprising the steps of: providing a substantially defatted soy protein material; extracting soy protein from the material with water; removing solids from the material to obtain a protein extracted liquid; subjecting the protein extracted liquid to ultrafiltration wherein the ultrafiltration is conducted using an ultrafiltration membrane having a molecular weight cut-off between about 10,000 and about 60,000; pasteurizing the protein extracted liquid; and drying the protein extracted liquid.
