Abstract: Disclosed is a uniquely textured pet food in the form of low-intermediate moisture, but highly-palatable, resilient, soft, meat-like chunks. These soft, chewy chunks are expanded internally and have a substantially-continuous, fibrous, highly-irregular surface. This pet food is prepared by relatively high pressure extrusion of a plasticized, meat based formulation to achieve expansion.

Abstract: The invention relates to food products having a gelled or thickened aqueous phase, a pH value of 2.5 up to 5.0 and in the case of milk products up to the neutral range about 7.5. Applicants have found unexpected benefit in using crude pectinaceous material of which the degree of esterification is or has been reduced to less than 20%, and preferably less than 10%, as the thickening or gelling agent in such products.

Abstract: Meats and meat by-products which are considered to be inedible for human consumption but which may be used in the production of animal foods are decharacterized by mixing such products with a U.S. Department of Agriculture approved FD&C decharacterizing color. When such decharacterized meat products are to be used in the production of an animal food, the decharacterized meat is counter-colored by mixing with a color which is complementary to the decharacterizing color to provide the inedible meat product with a substantially natural meat-like color. Approved FD&C colors and blends of approved FD&C colors, which are the complementary color of the FD&C color used in decharacterizing the meat product, are used in counter-coloring the meat product. Lakes of such colors and color blends may also be used.

Abstract: A dry particulate porous expanded animal food is disclosed comprised of chunks or kibs of a mixture of farinaceous and proteinaceous ingredients. The kibs are then coated with a fat/dextrin material emulsion. The product is characterized by its improved ability to resist rapid extensive hydration when liquid is added and hence remain crispy in liquid for substantial periods of time. The product is also of improved palatability and appeal to pets.

Abstract: The present invention is concerned with the preparation of an improved expanded dry animal food composition based on farinaceous and proteinaceous constituents. Chunks or kibs of the expanded product are coated in separate layers with a first layer of dextrin material and a second exterior layer of fat. The kibs may optionally be coated with a gravy forming material such that a gravy is formed when water is added. The coating of the dextrin material serves to retard the rate of hydration when water is added such that the chunks retain their crunchy texture and structure for longer periods of time with the result that the product is of improved animal acceptance.
