ABSTRACT
Seed oils of seven Amaranthus varieties, representing two species, namely, A. hypochondriacus and A. caudatus were obtained by solvent extraction method. Oil content for the varieties ranged from 4-8%. Physico-chemical characterization of seed oils showed them to be of good quality with trace moisture content (≤0.03%), with low acid values (2.45-4.08 mg KOH/g) and peroxide values (2.17-3.89 meq O2/kg). High iodine values (104.40-113.81 g I2/g) showed presence of high unsaturated fats. The saponification values were also high (173.15-190.50 mg KOH/g). Lipid profiles of Amaranthus seed oils were determined using GC-MS which demonstrated that linoleic acid, oleic acid and palmitic acid were the major fatty acids of oils. The unsaturated fatty acid content of Amaranthus seed oils was less than 70%, while the essential fatty acid content for Amaranthus seed oils was <40%.
Key words: Physico-chemical properties, fatty acid composition, Amaranthus seed oils, Gas Chromatography-Mass Spectrometry (GC-MS).
