摘要
Abstract
The removal of pigments from crude polysaccharides from yellow skin onion was investigated.AB-8 was found to be the best adsorbent for pigments in yellow skin among 8 types of macroporous adsorption resin tested.The removal rate of pigments was 86.71% and the retention rate of polysaccharides when 20 mL of 2792.5 mg/L crude polysaccharide solution at pH 5.0 and 40 ℃ was made to flow through 1 g of AB-8 column at a velocity of 2792.5 mg/L.In conclusion,the resin is suitable for the decolorization of polyssacharides from yellow skin onion.关键词
