<p>An animal collagen or gelating based crumble, and processes for the preparation of the particluate crumble, are useful in the preparation of collagen or gelatin based compositions. The crumble is prepared by extracting animal collagen from an animal tissue source and combining the collagen with sufficient water to form a composition comprising about 15-45 wt. % animal collagen and about 0.01-5 wt. % of a stabilizer or preservative. Such a combination of materials can be solidified and then processed into a large particulate format. The large particulate comprises a regular or amorphous shaped, roughly crumbled or roughly divided, crumble product. The typical particle size of a majority of the crumble is about 0.2-5 cm. The crumble is easily manufactured, packaged, stored, handled and distributed. The crumble can be easily used as is. The material melts easily into a use locus. The crumble is also particularly adapted to a use in combination with an aqueous diluent to form an aqueous animal collagen or gelatin solution that have a variety of uses. The aqueous solution of the crumble can be made with minimal heating to dissolve the crumble in the aqueous liquid.</p> |
