Abstract:
:Phenolics were extracted from powdered pomegranate peel using water, methanol, acetone and ethyl acetate (EtOAc), respectively. The antiliperoxidant activity of the extracts on lard was studied by peroxide value method. All the extracts showed enhanced inhibitory effect on lard peroxidation with the increase of phenolic concentrations. Acetone extract exhibited the highest antiliperoxidant activity followed by water, methanol and EtOAc extracts. Acetone extract at 0.1% (w/w) and water extract at 0.2% (w/w) demonstrated an antiliperoxidant effect close to that of tea polyphenols (0.02%, w/w) and higher than that of BHT (0.02%, w/w). At 0.2% (w/w), acetone extract showed a higher inhibitory activity on lard oxidation than that of tea polyphenols and BHT. Owing to the high antiliperoxidant property, acetone extract may have possible application in the food industry.
