Evaluation of physicochemical properties, fatty acid composition and oxidative stability of Camelina sativa (DH 1025) oil

Camelina (Camelina sativa) is an oilseed crop from the Brassicaceae family, which is rich in oil (28- 40%) and omega-3 fatty acids. This crop is able to grow in different climate and soil conditions, and compared to other oilseeds requires less water, fertilizer and pesticides. In this study, Camelina seeds (DH1025) were planted in Kermanshah, Kangavar and Sarpol-e Zahab, and then its oil properties were studied in detail. Through gas chromatography (GC) method, 13 different fatty acids were detected in the extracted oils. Four major fatty acids in all oil samples were linolenic acid (28.03-30.31%), linoleic acid (18.64-19.33%), oleic acid (15.44-18.36%) and eicosanoic acid (15.94-17.48%), respectively. Average amounts of iodine index, saponification value, specific gravity, refractive index and oil acidity of this crop were 143.5, 184.2, 0.915, 1.468 and 0.41 respectively and its 1000-seed weight were equal to 1.017. The oxidative stability of Camelina oil was 10.5 hours.
