Abstract:

A method of extracting and fractionating collagen-rich proteinaceous materials and derivatives from poultry skin tissue and the development of the proteinaceous materials to collagen-based protein ingredients that can function as meat replacer, texturizer, binder/filler, stabilizer, or protective colloids in processed meat products. The insoluble and soluble collagen products, collagen-based protein ingredients, water-dispersible collagen-based protein ingredients are produced by heating, separating, and rapidly cooling the solid-phase below its melting temperature to exploit reformation of the helical forms which produces a high concentration of coils, a phenomenon that accounts for its ability to form cold-set thermal reversible gels and gel strength.
