Abstract

ABSTRACT The effect of tyrosol (Tyr) and tyrosol acyl ester (TYr-Es) on thiobarbituric acid reactive substance, peroxide value, acid value, aldehyde content, fatty acid composition, and tyrosol content of mussel (Mytilus edulis) oil (MO) during accelerated storage at 60°C was evaluated. The results indicated that TYr-Es and TYr showed effective protection of MO against lipid oxidation. However, the poor solubility of TYr may lead to the formation of a suspension in oils. Therefore, TYr-Es with good lipid solubility and oxidation resistance may serve as potential antioxidant in marine oils highly enriched in long chain omega-3 polyunsaturated fatty acids in phospholipid form.
