Abstract
Abstract The palatability of animal foods is increased by incorporating therein an effective amount of a palatability improving composition prepared by reacting an aqueous mixture of protein and emulsified fat with lipase and protease. For dry animal foods, a fat such as bleachable fancy tallow or butter oil is preferably emulsified with a proteinaceous emulsifier, subjected to the action of the enzymes and then sprayed onto the animal food as an emulsion. For intermediate moisture animal foods, a meat slurry is preferably treated with the enzymes and then combined with the other ingredients of the animal food.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
103 words
A process for improving the palatability of an animal food which comprises: conditioning an aqueous meat slurry, comprising fat and protein, by emulsifying the fat in the meat slurry with the water present in the slurry, and treating the meat slurry, containing the emulsified fat and the protein, with lipase and protease in amounts, under conditions of pH and temperature, and for a time, effective to cause an enzymatic reaction resulting in the production of a palatability improving composition; and incorporating the palatability improving composition into the animal food in an amount which is effective to increase the palatability of the animal food.
Claim 2
Dependent Claim
103 words
A process for improving the palatability of an animal food which comprises: conditioning an aqueous meat slurry, comprising fat and protein, by emulsifying the fat in the meat slurry with the water present in the slurry, and treating the meat slurry, containing the emulsified fat and the protein, with lipase and protease in amounts, under conditions of pH and temperature, and for a time, effective to cause an enzymatic reaction resulting in the production of a palatability improving composition; and incorporating the palatability improving composition into the animal food in an amount which is effective to increase the palatability of the animal food.
Claim 3
Dependent Claim
34 words
A process according to claim 1 wherein the palatability improving composition is incorporated into the animal food by admixing it with a mixture comprising fat, carbohydrate, protein, vitamins and minerals and extruding this admixture.
Claim 4
Dependent Claim
16 words
A process according to claim 2 wherein the animal food is a nutritionally balanced dog food.
Claim 5
Dependent Claim
31 words
A process according to claim 2 wherein the palatability improving composition is employed in an amount of from about 5% to about 30%, based on the weight of the animal food.

Claim 12
Dependent Claim
101 words
A process for improving the palatability of an animal food which comprises: a. conditioning a mixture of fat and protein by (i) providing a liquid fat, a protein and water, (ii) emulsifying the fat, (iii) reacting the resulting emulsion containing protein with amounts of lipase and protease, under conditions of pH and temperature, and for a time, effective to enzymatically react with the emulsion containing the protein to result in the production of a palatability improving composition; and incorporating the palatability improving composition into the animal food in an amount which is effective to increase the palatability of the animal food.
Claim 13
Dependent Claim
101 words
A process for improving the palatability of an animal food which comprises: a. conditioning a mixture of fat and protein by (i) providing a liquid fat, a protein and water, (ii) emulsifying the fat, (iii) reacting the resulting emulsion containing protein with amounts of lipase and protease, under conditions of pH and temperature, and for a time, effective to enzymatically react with the emulsion containing the protein to result in the production of a palatability improving composition; and incorporating the palatability improving composition into the animal food in an amount which is effective to increase the palatability of the animal food.
