Abstract
Total lipid (TL), neutral lipid (NL), and phospholipid (PL) fractions were extracted from bluefish (Pomatomus saltatrix) white and dark muscle with skin. The effects of each fraction on the oxidative stability of a refined salmon oil model system was measured by monitoring changes in the 2‐thiobarbituric acid assay and decreases in the ratio of docosahexaenoic acid (DHA) to palmitic acid (C22:6/C16:0) following incubation at 55°C or 180°C. Phospholipid fractions at 2.5% and 5.0% (wt/wt) of oil improved the oxidative stability of oils incubated at both temperatures compared to controls, TL‐ and NL‐supplemented oils at similar concentrations. Phospholipid fractions exhibiting antioxidant properties contained an average of 34% DHA as compared to only 15% in the NL and TL fractions.This publication has 18 references indexed in Scilit:
