Effect of Adding Pomegranate Peel Extracts on the Stability of Grape Seeds Oil During Storage

Abstract

The effect of adding pomegranate peel extract to Grape seed oil and studying the effect of addition on the stability of oil during storage period and comparing the results with a sample of grape seed oil during the storage period fortified with the same percentage of BHA. It was found that the addition process improved the physicochemical properties of oil, as it was noted that the value of peroxide number of oil which treated with pomegranate extract amounted to 34.07 μg / g, while the value of the same characteristic for the oil treated with BHA was 28.02 μg / g It was found from study of the rest of traits that their value was less than that of the untreated grape seed oil, and it was found that the absorption of light was less in the treated oil than in the untreated oil. total phenols. And the rest of the characteristics, but it is not having ability of BHA, which works to maintain levels of physicochemical properties within acceptable limits almost.
