Abstract
Abstract This invention relates to unitized, compact, chew-resistant products with or without structure-supporting fibers. These products are prepared from animal foods which are preferably in a dry, shelf-stable form such as dried meals, dried fish, dried dairy products, fish meal, fish flour, cereals, flours, carbohydrates, dried fruits, etc., with or without food additives or supplements such as vitamins, minerals, medicinals, etc., for example chemicals, enzymes, etc., capable of removing plaque or tartar frm the animal's teeth, etc. These products are prepared by: (1) Adding sufficient water to wet the product without affecting its free flowing character; (2) Compacting the wetted product at high pressure; (3) Baking the product.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
139 words
A process of preparing a hard, unit-integral, unitized, self-contained, compact chew-resistant animal food product comprising the steps of (1) compacting animal food of a free flowing nature and containing sufficient water to wet said animal food without affecting its free flowing nature, prior to compacting, said water being present in said animal food in an amount of at least about 7.5% by weight of the components thereof dry, said compacting being carried out at a pressure of at least about 100 psi, and (2) baking said so-compacted wet animal food at a temperature of at least about 200° F. for at least about 0.5 hour until said water is present in said animal food in the final amount of at least 5.5% by weight and said so-compacted animal food has a density of at least 0.5 oz/in 3 .
Claim 2
Dependent Claim
139 words
A process of preparing a hard, unit-integral, unitized, self-contained, compact chew-resistant animal food product comprising the steps of (1) compacting animal food of a free flowing nature and containing sufficient water to wet said animal food without affecting its free flowing nature, prior to compacting, said water being present in said animal food in an amount of at least about 7.5% by weight of the components thereof dry, said compacting being carried out at a pressure of at least about 100 psi, and (2) baking said so-compacted wet animal food at a temperature of at least about 200° F. for at least about 0.5 hour until said water is present in said animal food in the final amount of at least 5.5% by weight and said so-compacted animal food has a density of at least 0.5 oz/in 3 .
