fatty acid composition and mineral contents of pea genotype seeds

Metal, non-metal and and heavy metal contents of different pea genotype seeds were determined by inductively coupled plasma atomic emission spectrometry (icp-aes). for all genotypes, significant differences were observed in the mineral contents. potassium was the most abundant element, ranged from 10146.13 mg/kg (ps3048) to 13171.97 mg/kg (ps3053) (table 1). in addition, the phosphor content of pea seeds was found between 4004.31 mg/kg (ps 30100) and 5651.27 mg/kg (ps 3057). these pea genotypes contained 1562.32 mg/kg to 2034.28 mg/kg magnesium. zinc contetns of pea samples changed between 29.66 mg/kg (ps 3055) and 67.81 mg/kg (ps 4053 b). the oil contents of pea samples ranged from 0.84% (ps4053 b) to 3.59% (ps 3055). oleic acid is predominant fatty acid 12.95% to 45.02% followed by palmitic 13.68% to 77.28%, stearic (1.66% to 15.99%) acids. the highest oleic acid was found in ps3048 genotype (45.02%). the highest palmitic acid was found in ps4021 pea sample (77.28%). the current study contributes to the available information concerning the composition of several pea genotypes grown in turkey.
