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.Field of SearchOf animal fleshExtruding through restricted orifice to give desired final shape Animal flesh material Comminuted Single source Animal derived material is an ingredient other than extract or protein Size increase by puffing, or pore forming of solid material by heating Heat treatment of food material by contact with glyceridic fat or oil, e.g., potato chip frying, etc. Including water treatment With size reduction, e.g., mashing, cutting, etc. With separation of a constituent IMITATED, SIMULATED, ORNAMENTAL, THREE-DIMENSIONAL PRODUCT OR CONFECTIONARY PRODUCT HAVING CHILD-ORIENTED UTILITY Preparing or treating triglyceridic fat or oil, or processes of separating triglyceridic fat or oil from a starting material, e.g., rendering, etc. | |
