Phenolic compounds as antioxidants to improve oxidative stability of menhaden oil-based structured lipid as butterfat analog

چکیده

Phenolic compounds, including propyl gallate, 1-o-galloylglycerol, ferulic, gallic, caffeic, rosmarinic, and carnosic acids, tocopherols, butylated hydroxytoluene (BHT), were investigated as antioxidants to improve the oxidative stability of a structured lipid (SL) produced by enzymatic acidolysis menhaden oil with caprylic stearic acids. SL had similar physical properties butterfat but was more susceptible oxidation. The above phenolic compounds each added antioxidants. rosmarinic acid, or BHT showed highest during an accelerated oxidation test total (TOTOX) value around 250 after 18 days. Oxidation induction time (OIT) using differential scanning calorimetry good correlation test. A mixture 1-o-galloylglycerol tocopherols at 50:50 ppm strongest protective effect on (OIT = 115.1 min) compared other tested combinations same concentration < 100 min).
