ABSTRACT:
A method of forming soluble collagen fibers from raw animal hides is disclosed. Raw animal hides are treated with an aqueous solution of an alkali metal hydroxide and a dehydrating agent to remove the hair and fat therefrom to yield a substantially fat-free corium. The interfibular bonds of the collagen in the corium are stabilized with an aqueous solution of an alkali sulfate. The corium is neutralized and dissolved in an aqueous acid solution to yield a collagen solution. The pH of the aqueous collagen solution is adjusted to the isoelectric point of the collagen to precipitate the collagen fibers from the solution. The collagen fibers are dried. The collagen fibers so produced are useful in edible food, may be redissolved and further processed for a plurality of uses.
