Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
101 words
A dry, particulate, porous, nutritionally balanced animal food product comprising an expanded mixture of between 35 to 70% by weight farinaceous and from about 20 to 50% by weight proteinaceous ingredients, said animal food product having thereon a first coating of from about 1 to 8% by weight of a dextrin material selected from the group consisting of corn syrup, corn syrup solids, dextrins, and mixtures thereof and a second exterior coating of from 1 to 8% by weight of fat, said animal food product characterized by its improved resistance to rapid extensive hydration when mixed with liquid and improved palatability.
Claim 2
Dependent Claim
101 words
A dry, particulate, porous, nutritionally balanced animal food product comprising an expanded mixture of between 35 to 70% by weight farinaceous and from about 20 to 50% by weight proteinaceous ingredients, said animal food product having thereon a first coating of from about 1 to 8% by weight of a dextrin material selected from the group consisting of corn syrup, corn syrup solids, dextrins, and mixtures thereof and a second exterior coating of from 1 to 8% by weight of fat, said animal food product characterized by its improved resistance to rapid extensive hydration when mixed with liquid and improved palatability.
Claim 3
Dependent Claim
126 words
In a method of preparing an expanded, porous, dry, particulate nutritionally balanced animal food product wherein a mixture of between 35 to 70% by weight farinaceous and from 20 to 50% by weight proteinaceous ingredients is mechanically worked at elevated pressures and temperatures, extruded through a die orifice into atmosphere to cause said mixture to expand, cut into a desired shape and size, and dried, the improvement comprising coating said product with a solution of a dextrin material selected from the group consisting of corn syrup, corn syrup solids, dextrins and mixtures thereof, such that said product contains about 1 to 8% by weight of said dextrin material, and then applying a second exterior coating of from 1 to 8% by weight fat to said product.
Claim 4
Dependent Claim
