A puffable, thermoplastic composition derived from animal parts is prepared by drying substantially raw animal parts to a moisture content between 10% and 25%, comminuting those parts and mechanically defatting the comminuted particles to a fat content of less than 18%. The defatted particles are macerated in an extruder at temperatures less than 330°F. and under sufficient pressure to cause gelatinization of the particles. The resulting thermoplastic moldable mass is extruded to a shape sustaining form and cooled to below 215°F., after which it is cut into puffable pellets. The pellets will be at least partially gelatinized animal parts, have a moisture content of less than 15%, a fat content of less than 15% and the protein thereof will not be subjected to denaturing temperatures in excess of 330°F. The pellets may be puffed in hot oil to a product which resembles fried port skins or they may be thermo-formed into a decorative shape, e.g., in the shape of a chewable dog bone.

A method for producing a puffable, thermoplastic composition derived from animal parts comprising: (1) drying substantially raw animal parts which contain no more than 25% hot oil rendered parts to moisture contents between 10% and 25%; (2) comminuting the dried parts to particles having dimensions

A method for producing a puffable, thermoplastic composition derived from animal parts comprising: (1) drying substantially raw animal parts which contain no more than 25% hot oil rendered parts to moisture contents between 10% and 25%; (2) comminuting the dried parts to particles having dimensions no greater than ¼inch; (3) mechanically defatting the comminuted particles at temperatures below 200°F. to an average fat content of less than 18% whereby protein contained in the particles is not substantially denatured and wherein mechanical means are used for said defatting; (4) macerating the defated particles in an extruder barrel at temperatures between 250°F. and 330°F. and under sufficient pressure to cause mastication and gelatinization of the particles and to form a thermoplastic moldable mass; (5) extruding the moldable mass into a shape sustaining extruded form; (6) cooling the extruded from to below 215°F.; and (7) cutting the cooled form into puffable pellets.
