Fatty Acid Composition in Some Species of Walnuts Grown in Turkey

Abstract

Walnut samples obtained from nineteen different 1: Hartley, 2: 206, 3: Serr, 4: Mitlant, 5: Fernor, 6: Pedro, 7: Payne, 8: Oguzlar, 9: Fernette, 10: 46, 11: Howard, 12: Akca 2, 13: 39, 14: Sen 1, 15: Maras 18, 16: 91, 17: Sili yerel, 18: 58, 19: 46, in Anatolia. The present study describes the determination of fatty acid composition of the oil samples obtained from some walnut and the comparison of variations species. The fatty acid compositions of walnut samples were determined by Shimadzu 15-A Gas Chromatography. According to the results, fatty acid composition of the walnut samples is significantly varied depending on each species.
