  • Patent number: 4104407
    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.
