  • Particulate dog food palatability enhancer and process
    Patent number: 4804549
    Abstract: Disclosed is a composition which improves the palatability of dog foods and the methods of making and using it. According to the process, a high free fatty acid fat is emulsified with an encapsulating binder and dried. The fat will preferably contain at least 10% free fatty acids based on the weight of the fat. The free high fatty acid content can be achieved by overt addition or generation by saponification or enzyme action. The composition is dried by spray drying or drum drying.

  • Enzyme digestion for a dog food of improved palatability
    Patent number: 4393085
    Abstract: The object of the present invention is to provide an improved process for preparing a dog food comprising farinaceous and meaty ingredients.This invention recognizes for the first time that the palatability of dog food can be improved when at least a portion of the farinaceous ingredients are subjected to both an amylase and protease enzyme digestion and intermixing an enzymatically modified proteinaceous material to form a reaction slurry mixture. The resulting combined reaction slurry mixture can be incorporated into the dog food by coating it on the surface or admixing it with the other dog food ingredients and thereby incorporating it internally. Preferably, the combined reaction slurry is admixed with the other ingredients to form a plastic mass which is then shaped and expanded by extrusion.
