Abstract

On surveying the market of Mysore city, 11 different types of edible oils were available for sale which included crude oils, refined oils and blended oils. Nineteen samples of oil produced from groundnuts, soybeans, sunflower seed, palm fruit, mustard, olive, coconuts, rice bran, sesame (gingelley) and safflower seed along with 5 blended oils (2 commercial and 3 laboratory preparations) were analyzed for their physico-chemical properties like colour, free fatty acids value (FFA) peroxide value(PV) and tocopherols content. Colour, FFA and PV were found to be higher in crude oils than the refined oils. Among the oils analyzed, crude palm oil was found to be the richest (260 mg %) and coconut oil was found to be the poorest source (10 mg%) of tocopherols. However, on blending coconut oil with sesame oil, the tocopherol content could be increased appreciably in the blend. Thus, blending can be used as a means for the enrichment of tocopherol content.
