Methods for extending the shelf-life of food compositions containing polyunsaturated fatty acids

摘要

A process for preparing a food composition by mixing a nutritive base with at least one long chain polyunsaturated fatty acid; cooking the resulting mixture at a temperature not less than about 50° C.; adding to the food composition at least one oxidatively protected long chain polyunsaturated fatty acid; and packaging the resulting composition in an oxygen depleted environment within a sealed container to provide the food product that exhibits (1) acceptable palatability to an animal and (2) a shelf-life of at least about 6 months when stored at ambient temperature without opening the container.
