    摘要: This invention describes a collagen fiber reconstituted rawhide useful in the production of pet chews, and a method for making the same. Beginning materials include animal skins with hair, depilated limed splits and leftovers from the manufacture of rawhide pet chews. The materials are pretreated, ground, subjected to acid treatment to swell and separate the collagen fibers that comprise the animal hide, further ground into pulp, vacuum filtered, mixed with a dehydration agent that chemically shrinks the expanded fibers, drained, formed and dried into sheet and finally exposed to a cross-linking agent to increase the adhesive strength of the end product. Edible materials, including meats, may be added to the solution prior to draining, to enhance the nutritional value and palatability of the final product, and the reconstituted rawhide sheets may be bleached for appearance.
