Oil Content and Oil Quality Properties of Some Grape Seeds


Abstract: In the present study, the oil contents and some oil quality properties of seeds taken from 18 grape cultivars were examined. The results showed that the oil concentration of seeds ranged from 11.6 to 19.6%. Grape seeds were rich in oleic and linoleic acids, ranging from 17.8 to 26.5% and 60.1 to 70.1%, respectively. The degree of unsaturation in the grape seed oil was over 86%, and the average concentration of total tocopherol in oil was around 454 mg/kg. The results indicate that grape seed oil could be an important source for production of an edible vegetable oil and lowering wine production costs.
