Abstract
The present invention generally relates to inhibition of oxidation of polyunsaturated lipids by mixing the polyunsaturated lipids with a combination of polyamines providing a unique anti-oxidative effect on the polyunsaturated lipids. A especially advantageous combination of polyamines used in this regard includes spermine and a different linear aliphatic polyamine, such as spermidine, putrescine, or mixtures thereof. The rate of off-flavor development is significantly reduced in polyunsaturated lipids blended with such combinations of different polyamines. In addition, polyunsaturated lipid-containing materials and compositions can be stabilized using edible, non-toxic anti-oxidants based on such polyamine combinations. Omega-3 fatty acids and compositions containing them are especially well-suited for processing in this manner. The stabilized polyunsaturated lipid-containing products obtained in this manner have extended shelf-life while permitting the health and nutritional value of the treated lipids to be more fully accessed.
