In this study, no clear relationship existed between the stability of the oil and the content of polyunsaturated fatty acids. It is more likely that the stability of the oil is influenced by factors such as the positions of the individual fatty acids within the triacylglycerol molecule and the presence of tocopherols, carotenoids, free fatty acids and sterols as suggested by Neff, Mounts, Rinsch, Konishi & El-Agaimy, 1994.
