Abstract

Samples of palm olein were irradiated with y-rays up to 12 kGy. The extent of peroxidation in irradiated samples was determined by conjugable oxidation products (COP) assay and the result were compared with the UV absorbance at 232 mm. The two parameters were poorly correlated (r 0.6321) within the range of doses used. The effect of gamma-irradiation is mainly to oxidise linoleic acid (C18:2) as this component is the major diunsaturated fatty acid in palm oil.
