Abstract:

Pomegranate (Punica granatum L.) peel possess greater antioxidant potential as well as total phenolics especially extracted by ethanol (3.06 and 82.52) and methanol (3.56 and 83.16), can be used to inhibit lipid oxidation in oil. Pomegranate peel extract (500,750 and 1000 ppm/L) can be used as antioxidant source in the oil to replace commercial synthetic antioxidants. The peel extract addition showed positive effect on the enhancing quality of the oil as evaluated by maximum reduction in free fatty acids (0.2599±0.11%), iodine value (98.06±3.73%), saponification value (192.50±0.56mgKOH/g), peroxide value (2.067±0.44meq/kg) and TBARS (0.1203±0.02) compared to control (0.4667±0.10%, 112.99±3.81%, 194.58±0.88mgKOH/g, 17.648±1.04meq/kg and 0.1819±0.05) at highest level of peel extract (1000 ppm/L). The results of storage study revealed minimum deteriorative changes in sunflower oil blended with peel extract. It is concluded from results that pomegranate peel extract is good source of antioxidant and a potential non-synthetic source of antioxidants for oil stability.
