Fatty acids and mineral contents of common oil seed and kernels

Abstract

Oil contents of seeds were determined between 7,64 % (wheat germ) and 63,36 % (walnut) (p<0,05). The highest linolenic acid content was found in linseed oil (52,46 %). In addition, oleic acid contents of seed samples were found between 14,52 % (safflower) and 76,82 % (Hazelnut) (p<0,05). The highest mineral contents of samples were determined between 351 mg/kg to 12536 mg/kg Ca, 2589 mg/kg to 20567 mg/kg K, 1596 mg/kg to 3710 mg/kg Mg, 2603 mg/kg to 11261 mg/kg to 11261 mg/kg P. Mineral contents of sweet pumpkin were found higher than green pumpkin. While hazelnut contain 1737 Ca, 5389 K, 1955 Mg, 2603 P and 1540 mg/Kg S, walnut contained 1408 Ca, 3870 K, 1935 Mg, 3711 P and 857 mg/Kg S (p<0.05). Black cumin contained 5384 Ca, 9326 K, 2465 Mg, 5638 P and 2042 mg/Kg S. As a result, oilseeds can used directly and/or indirectly (as cake) as both food and feed in terms of fatty acid composition and nutrients.
