Abstract

In the current study, for the first time, the oxidation stability of the extracted edible oil from Sardasht red grape at three different accelerated deteriorative conditions (oven, microwave and ultraviolet (UV) irradiation) was investigated. In this context, the peroxide value (PV), conjugated diene value (CDV), carbonyl value (CV), radical scavenging activity (RSA) and oil/oxidative stability indices, as well as fatty acid composition and total tocopherol content, were evaluated. Sardasht grape seed oil as a rich oil in unsaturated fatty acid (about 87%) contains linoleic acid in terms of the principal fatty acid (70.4 ± 1.8%). The excessive oxidative stability of crude oil can be correlated with the extreme content of natural antioxidants (tocopherols and tocotrienols). The findings showed that Sardasht red grape seed oil could be approached as new source of edible oil with acceptable oxidative stability.
