Abstract

The properties of some extensively cultivated sunflower seed varieties in Turkey and their oils were investigated. 1991-1992 crop year sunflower varieties harvested from Trakya University, Tekirdag Agricultural Faculty, Experiment field of Crop Science Department were used as research materials. The oil content, fatty acid composition and tocopherol content of sunflower seeds in 1991 and 1992 crop years were determined as 44.2-51.2% (on dry weight basis), 43.0-51.5% (on dry weight basis); oleic acid 14.8-18.5%, 32.9-40.1%; linoleic acid 69.5-74.5%, 49.7-55.7% and tocopherol content (as alpha-tocopherol) 648-860 mg/kg, 524-880 mg/kg, respectively. It was determined that the growing conditions significantly affected the fatty acid compositions of sunflower varieties studied. While the oleic acid content of the 1992 crop increased, the linoleic acid content of the same crop decreased compared to the 1991 crop.

摘要

对土耳其一些广泛种植的向日葵种子品种及其油的特性进行了研究。以1991 - 1992作物年度从恰纳卡莱大学农业学院作物科学系试验田收获的向日葵品种作为研究材料。测定了1991年和1992年作物年度向日葵种子的含油率、脂肪酸组成和生育酚含量，分别为44.2 - 51.2%（以干重计）、43.0 - 51.5%（以干重计）；油酸14.8 - 18.5%、32.9 - 40.1%；亚油酸69.5 - 74.5%、49.7 - 55.7%，生育酚含量（以α-生育酚计）分别为648 - 860 mg/kg、524 - 880 mg/kg。结果表明，生长条件对所研究的向日葵品种的脂肪酸组成有显著影响。与1991年作物相比，1992年作物的油酸含量增加，而同一作物的亚油酸含量下降。
