Abstract

Samples of palm oil and palm kernel oil (PKO) products were collected from two palm oil processing premises which were named as premise A and B. These samples were then analysed for dioxins and dioxin-like polychlorinated biphenyls (PCBs) content. The concentration of dioxins in the palm oil and PKO samples from premise A ranged from 0.128 World Health Organization-toxic equivalency (WHO-TEQ) pg/g fat to 0.189 WHO-TEQ pg/g fat while the concentration in samples collected from premise B ranged from 0.149 WHO-TEQ pg/g fat to 0.540 WHO-TEQ pg/g fat. Meanwhile, dioxin-like PCBs concentration ranged from 0.336 WHO-TEQ pg/g fat to 0.546 WHO-TEQ pg/g fat for premise A and 0.345 WHO-TEQ pg/g fat to 0.346 WHO-TEQ pg/g fat for premise B. The total numbers of samples analysed were 35 and the levels exhibited were below the maximum level of 0.75 WHO-TEQ pg/g fat and 1.25 WHO-TEQ pg/g fat imposed by the European Commission for dioxins and the sum of dioxins + dioxin-like PCBs content in vegetable oils.
