Abstract
Abstract The present invention identifies certain compounds, naturally present in raw meat, which are especially taste active in the dog. These compounds, which have been found to maximally activate taste neurons, are L-proline, L-cysteine, L-histidine, L-lysine, inosine 5'-triphosphate (ITP), inosine 5'-diphosphate (IDP), and adenosine 5'-triphosphate (ATP). Application of these compounds to dog foods in effective amounts can increase their palatability for dogs.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
72 words
A process for improving the palatability of a nutritionally balanced dog food containing protein, fat, carbohydrates, vitamins and minerals, consisting essentially of incorporating into the dog food an amount of a palatability improving material selected from the group consisting of L-proline, L-cysteine, L-histidine, L-lysine, inosine 5'-triphosphate, inosine 5'-diphosphate, adenosine 5'-triphosphate or a combination of these; the amount of the palatability improving material being effective to increase the palatability of the dog food.
Claim 2
Dependent Claim
72 words
A process for improving the palatability of a nutritionally balanced dog food containing protein, fat, carbohydrates, vitamins and minerals, consisting essentially of incorporating into the dog food an amount of a palatability improving material selected from the group consisting of L-proline, L-cysteine, L-histidine, L-lysine, inosine 5'-triphosphate, inosine 5'-diphosphate, adenosine 5'-triphosphate or a combination of these; the amount of the palatability improving material being effective to increase the palatability of the dog food.
Claim 3
Dependent Claim
27 words
A process according to claim 1 wherein the palatability improving material is employed in an aqueous gravy at a level of from 0.1 to about 500 mM.
Claim 4
Dependent Claim
13 words
A process according to claim 1 wherein the palatability improving material is L-proline.
Claim 5
Dependent Claim
13 words
A process according to claim 1 wherein the palatability improving material is L-cysteine.
Claim 6
Dependent Claim
13 words
A process according to claim 1 wherein the palatability improving material is L-histidine.
Claim 7
Dependent Claim
13 words
A process according to claim 1 wherein the palatability improving material is L-lysine.
Claim 8
Dependent Claim
14 words
A process according to claim 1 wherein the palatability improving material is inosine 5'-triphosphate.
Claim 9
Dependent Claim
14 words
A process according to claim 1 wherein the palatability improving material is inosine 5'-diphosphate.
Claim 10
Dependent Claim
14 words
A process according to claim 1 wherein the palatability improving material is adenosine 5'-triphosphate.
Claim 11
Dependent Claim
83 words
An improved process for feeding dogs consisting essentially of the steps of: (a) preparing a nutritionally balanced dog food containing protein, fat, carbohydrates, vitamins and minerals; (b) incorporating into said dog food a flavor therefor selected from the group consisting of L-proline, L-cysteine, L-lysine, L-histidine, inosine 5'-triphosphate, inosine 5'-diphosphate, adenosine 5'-triphosphate, and combinations of these, wherein the amount of said flavor is effective to increase the palatability of the dog food when consumed; and (c) feeding the resulting flavored dog food to dogs.
