Determination Of Fatty Acids In Some Grape Cultivars By Gas Chromatography Mass Spectrometry

ABSTRACT: In the present study, seeds of five grape varieties, grown in the West Azarbaijan (Iran), were examined for determination of fatty acids composition. The results revealed that grape seeds were rich in linoleic acids, palmitic acid and stearic acid ranging from 66.37 to 81.56%, 7.91 to 11.49% and 3.61 to 5.81%, respectively. The highest linoleic acid content was found in Shirazi grape, while Rezghi showed the highest palmitic acid content. Goye maleki showed higher stearic acid content than other cultivars studied. The linoleic and palmitic acids were the most useful parameters to discriminate the five grape varieties. The highest oleic acid content was found in Rasha which discriminated this variety from other cultivars. In conclusion, these grape seeds could be used as a food supplement to improve the nutritive value of the human diet. They can also be utilized as a source of fatty acids to obtain edible vegetable oil.
