dc.description.abstract : Amaranthus cruentus grains from Meru and Nyeri regions in Kenya were milled and oil extracted by the Bligh and Dyer method. Samples of oil from grains in the same regions extracted by cold pressing method were obtained from All Grain Company in Nairobi. Triacylglycerides (TAG) was the major component of neutral lipids in oil extracted by the two methods. In Dyer and Bligh method, TAG had a mean of 76.12% while cold pressed oil had 72.09%. Phosphatidylethanolamine (PE) was the major polar lipids component in both methods of extraction. In both methods of oil extraction, linoleic acid was the most abundant fatty acid. Other fatty acids that were also found to be present in high amounts in the two methods included: oleic acid (30–34%), palmitic acid (20–23%), stearic acid (2–3%) and linolenic acid (0.8–1.2%). There was no significant difference in the saponification, acid, peroxide and iodine values. The saponification values were quite high, 187.61–189.90. The peroxide values from both methods ranged from 3.10 to 3.17 while acid values from the same analysis ranged between 1.74 and 3.92. Iodine value was found to be between 77.02 in cold pressed oil to 78.77 in oil from Dyer and Bligh method. en_US
