Abstract

Abstract Protein fibers are prepared by forcing an alkaline protein solution through an orifice and simultaneously intimately contacting the protein stream with a fast acting acid gas traveling at a velocity greater than the protein stream. The fibers find particular use in meat analog preparations.
