Abstract

Provided herein is a method of preparing a palatability enhancer for a food composition comprising combining an animal fat source and one or more agents in an aqueous solution to form a mixture, wherein said agents are selected from amino acids, sugars, vitamins, vegetable oils, flavorants and flavour precursors, heating the mixture at a pressure of 110 kPa to 800 kPa, obtaining a palatability enhancer from the mixture, wherein the palatability enhancer comprises animal fat in an amount of at least 80 wt %. Further provided is a method of enhancing the palatablity of a food composition.

First claim

The invention claimed is:

1. A method of preparing a palatability enhancer for a food composition, the method comprising:
combining an animal fat source comprising animal fat and odorous compounds with one or more amino acids, one or more sugars, one or more vegetable oils, and water to prepare a mixture comprising an aqueous phase and a lipid phase, wherein the odorous compounds originate from decomposition of the animal fat and comprises odorous fatty acids;
heating the mixture at a pressure of 110 kPa to 800 kPa to a temperature of from 80° C. to 230° C.;
neutralizing the odorous fatty acids of the animal fat source to provide neutralized odorous fatty acids by adding a sufficient amount of an alkaline agent to the mixture; and
obtaining a palatability enhancer from the mixture by separating the aqueous phase from the lipid phase comprising the palatability enhancer,
wherein the palatability enhancer comprises the animal fat in an amount of at least 90 wt %.

2. The method of claim 1 , wherein the animal fat of the animal fat source is not rendered or filtered before combining with the amino acids, the sugars, the vegetable oils, and water to prepare the mixture.

3. The method of claim 1 , wherein the odorous compounds further comprise skatols, indoles, p-cresols, thiols, and biogenic amines.

4. The method of claim 1 , wherein the odorous fatty acids comprise branched chain fatty acids.

5. The method of claim 1 , wherein the odorous fatty acids comprise propionic acid, butyric acid, pentanoic acid, and hexanoic acid.

6. The method of claim 1 , wherein the animal fat source is fabricated meat and/or offal from slaughtering.

7. The method of claim 1 , wherein the animal fat source originates from one or more of cattle, poultry, horses, sheep, and pigs.

8. The method of claim 7 , wherein the animal fat source originates from pigs.

9. The method of claim 1 , wherein the mixture consists essentially of the animal fat source, the amino acids, the sugars, the vegetable oils, and water.

10. The method of claim 1 , wherein the aqueous phase has a pH from 3 to 4.

11. The method of claim 1 , wherein the aqueous phase has a pH of 3.

12. The method of claim 1 , wherein the aqueous phase has a pH of 4.
