A food composition in which omega-3 fatty acids are stabilized against oxidation is disclosed. The food composition contains about 4 to about 100 weight percent of the composition in which triglycerides containing omega-3 fatty acids (and other fatty acids) are stabilized against oxidation in the absence of encapsulation. The fatty acid portion of the oil in the completed food composition includes less than about 10 percent by weight linoleic acid, at least 75 percent by weight of monounsaturated plus saturated fatty acids, and at least 3 percent by weight omega-3 fatty acids. The food composition can also contain comminuted peanuts, e.g., peanut butter, in which case the composition is also stabilized against photo-oxidation and the fatty acid portion of the oil portion of the food can contain less than about 15 percent by weight linoleic acid and at least 1 percent by weight omega-3 fatty acids. Methods of protecting a food composition from oxidation and photodegradation are also disclosed.

Une composition alimentaire dans laquelle les acides gras oméga-3 sont stabilisés à l~oxydation est présentée. Elle est composée de 4 à 100 % en poids environ de la composition où les acides gras oméga-3 (ou d~autres acides gras) sont stabilisés à l~oxydation en l~absence d~encapsulation. La part d~acides gras de l~huile de la composition alimentaire obtenue contient moins de 10 % en poids environ d~acide linoléique, au moins 75 % en poids d~acides gras monoinsaturés et saturés et au moins 3 % en poids d~acides gras oméga-3. La composition alimentaire peut également contenir des cacahuètes broyées, par ex., du beurre de cacahuètes, dans quel cas la composition est également stabilisée à la photo-oxydation et la part d~acide gras dans l~huile peut contenir moins de 15 % en poids d~acide linoléique et au moins 1 % en poids d~acides gras oméga-3. Les méthodes de protection d~une composition alimentaire de l~oxydation et de la photodégradation sont également communiquées.
