Powdered activated carbon is used in oils and fats refining to bleach and purify vegetable oils and fish oils. Actually, this powder makes it possible to detoxify crude fish oils and to eliminate contaminants like PAH, dioxin and PCB. Nevertheless, the powdered activated carbon used is painful because it is pulverulent. Nowadays, producers advise filtration plates filled with this powder. The aim of this study is to check the efficiency of such plates in the PAH elimination and verify the respect of the new 2011 regulation (2 μg/kg for benzo(a)pyrene, 10 μg/kg for the sum of benzo(a)pyrene, benzo(b)fluoranthene, benzo (a)anthracene and chrysene).
Key words: oils and fats / contaminant / PAH / filtration / plates filled with activated carbon
