Abstract:

The paper aimed at studying on decoloration of hsian-tsao gum with activated carbon, and the optimum conditions were given by employing the factors of afecting decolorization. The best result was obtained when activated carbon dosage was 2.5%, decolorization temperature was 60 ℃ and decolorization time was 50 min, under which the decolorizing rate reached 92.3% and the loss of polysaccharide was 20.5%.
