TREATMENT OF VEGETABLE OILS OR ANIMAL FATS WITH SULFUR OR NITROG EN DONOR COMPOUNDS FOR ANIMAL FOOD FLAVORINGS

摘要

Oils or fats from plants and/or animals are chemically treated to create flavor/palatability enhancer (FPE) products for use with animal foods, such as dog or cat food. This method involves mixing triglycerides (from the oil or fat) with sulfur and/or nitrogen donor compounds, such as sodium sulfide. The mixture is cooked at a temperature close to boiling, or higher if pressure-cooking is used, for a period of time sufficient to break down large numbers of triglyceride molecules into their constituent fatty acids and other fragments. Under suitable cooking conditions, the organic fragments will react with sulfur and/or nitrogen atoms from the donor compound(s), to form relatively small organic molecules containing sulfur and/or nitrogen.
