Fatty Acid Composition and Mineral Contents of Pea Genotype Seeds

Abstract

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.
