| dc.description.abstract | Crude palm oil contain carotenoid pigment which has colour red-yellow with 600-1000 ppm p-carotene The carotenoid pigment especially p-carotene is important of vitamin A precursor Most of carotenoid's palm oil defective in refining process to produce light-coloured oils. Steps by step concentrated after transesterifcation have done with sodium methoxide catalyst and saponi-fication, soon afterward examining combination of transesterification-saponifi- cation technique. Optimum transesterification got by reaction mehanol and crude palm oil with molar ration 8:1, with additional 1% NaOH in temperature 60 °C for an hour, obtained 787.35 ppm total carotenoid with 78.37% p-catotene. Carotenoid concentrated with finest saponification obtained by reaction KOH and crude palm oil with molar ratio 5.78:1 within methanol solvent as much as jive time's weights of crude palm oil This process obtained 14,970.09 ppm total carotenoid with 78 75% p-catotene hence risen total carotenoid and p- catotene as much as 24 time's of crude palm oil. Saponification process not significant with combination process. | en |
