| Abstract: | In order to improve the purity and the property of the pineapple crude polysaccharide. The effects of powdered actiearbon and chitosan on decolorizing of pineapple crude polysaccharide were studied. By using orthogonal test, the optimum process conditions were reached as： when the amount of acticarbon was 1.0%, pH value of solution was 3.0 and the decolorizing time was 0.5 hour, the recovery rate of polysaccharide and the adsorption rate of pigment were 93.09% and 86.5 %, respectively; when using chitosan to decolorize, the amount of chitosan 5%, the decolorizing time was 0.75 hour and the decolorizing temperature was 45℃, recovery rate of polysaccharide and the adsorption rate of pigment were 95.23% and 74.3%, respectively. |
