mulberry seed oil is rather poor in linolenic acid. Low levels of linolenic acid are desired in edible oils, because high levels of this fatty acid can cause unfavourable odor and taste. Additionally and because linolenic acid is easily oxidized due its three double bonds on the hydrocarbon chain, the stability and/or shelf-life of an oil rich in linolenic acid would be too short (Baydar & Akkurt, 2001).
