Bleachability of crude palm oil was studied with respect to oxidation state of the oil at time of bleach, amount of bleaching clay needed, and the effects of an antioxidant treatment with tert-butyl-hydroquinone (TBHQ) on oxidation reactions. These studies confirm the adverse effects of oxidation on bleachability of palm oil and the effectiveness of TBHQ in preserving bleachability. Citric acid was shown to benefit only old oxidized oils. TBHQ was effective in the laboratory and at a full-scale plant experiment in retarding onset and rate of oxidation reactions.
