Improvement of oxidative stability of soybean oil by blending with a more stable oil was investigated. Autoxidation of blends and interesterified blends (9:1, 8:2, 7:3 and 1:1, w/w) of soybean oil and palm olein was studied with respect to fatty acid composition, fatty acid location and triacylglycerol composition. Rates of formation of triacylglycerol hydroperoxides, peroxide value and volatil...

moringaceae, a monogeneric family in capparales (glucosinolate-containing species), includes 14 species. one of them is moringa peregrina (forssk.) fiori., a small tree, which grows in south east of iran. volatile constituents of seed coat and stem of m. peregrina were determined by gc and gc/ms. moreover, extracts of seed and different cultured cells were analyzed by tlc and gc. three volatile...
More than half the world's rainforest has been lost to agriculture since the Industrial Revolution. Among the most widespread tropical crops is oil palm (Elaeis guineensis): global production now exceeds 35 million tonnes per year. In Malaysia, for example, 13% of land area is now oil palm plantation, compared with 1% in 1974. There are enormous pressures to increase palm oil production for foo...
