Tripolyphosphate pet food palatability enhancers
View Patent ↗A palatability enhancing composition for extruded pet food containing at least one tripolyphosphate salt in an amount effective to enhance palatability and at least one ingredient selected from meat products, meat by-products, fish products, fish by-products, dairy products, dairy by-products, sources of microbial proteins, vegetable proteins, carbohydrates and amino acids. Methods for enhancing pet food palatability with the disclosed palatability enhancing compositions and extruded pet food compositions coated therewith are also disclosed.
1. A method of increasing the palatability of an extruded pet food product comprising spraying a liquid palatability enhancing composition including at least one sodium tripolyphosphate salt to said extruded pet food composition, wherein said palatability enhancing composition is applied in a quantity sufficient to contribute from about 0.01 to about 5.0 percent by weight of said at least one sodium tripolyphosphate salt to said pet food composition and said palatability enhancing composition further comprises at least one ingredient selected from the group consisting of meat products, meat by-products, fish products, fish by-products, dairy products, dairy by-products, sources of microbial proteins, vegetable proteins, carbohydrates and amino acids.
2. The method according to claim 1 , wherein said palatability enhancing composition is applied in a quantity sufficient to contribute from about 0.05 to about 2.0 percent by weight of at least one sodium tripolyphosphate salt to said pet food composition.
3. The method according to claim 1 , wherein said liquid composition has a pH between about 2 and about 9.
4. The method according to claim 1 , wherein said extruded pet food composition is a dry cat food.
5. The method according to claim 1 , wherein said extruded pet food composition is a semi-dry cat food.
6. A liquid palatability enhancing composition for extruded pet food, said composition comprising from about 5 to about 50% by weight of at least one sodium tripolyphosphate salt and at least one ingredient selected from the group consisting of meat products, meat by-products, fish products, fish by-products, dairy products, dairy by-products, sources of microbial proteins, vegetable proteins, carbohydrates and amino acids.
7. The composition of claim 6 , wherein said composition has a pH between about 2 and about 9.
8. An extruded pet food composition comprising a spray-applied palatability enhancing quantity of the composition of claim 6 , wherein said quantity is sufficient to contribute from about 0.01 to about 5.0 percent by weight of at least one sodium tripolyphosphate salt to said pet food composition.
9. The pet food composition of claim 8 , wherein said palatability enhancing composition is present in a quantity sufficient to contribute from about 0.05 to about 2.0 percent by weight of at least one sodium tripolyphosphate salt to said pet food composition.
10. The pet food composition of claim 8 , comprising a dry cat food.
11. The pet food composition of claim 8 , comprising a semi-dry cat food.
