摘　　要：为了研究莼菜多糖的脱色条件,本文以脱色率为主要测定指标,首先对比了不同类型的树脂对莼菜多糖的脱色效果,然后通过树脂种类、脱色温度、脱色p H的单因素实验和正交实验对脱色工艺参数进行了优化。结果表明:采用大孔树脂NKA-9树脂,在脱色温度55℃和脱色p H为4的条件下,莼菜多糖溶液的脱色率可达到79.22%,多糖保留率为67.54%,蛋白质去除率为55.75%。该脱色方法工艺简单,效果好,可用于莼菜多糖的脱色。In order to study the Brasinia schreiber polysaccharides decolonization condition, the decolorization capability of different kinds of resins was compared taking decolorizing rate as major selection standard. Then through the single factor experiment and orthogonal experiment of resins species, decolorization temperature and decolorization pH, the decolorization process parameters was optimized. The Result showed that NKA- 9 resin had the best decolorization ability, under the decolorization temperature 55 ℃ and pH was 4, the decolonization rate of the Brasinia schreiber polysaccharides solution reached 79.22% , the Brasinia Schreiber polysaccharide retention rate was 67.54% ,the protein removing rate was 55.75% .The decolorization process was simple, the effect was good, could be used as a decolorization method of Brasenia schreberi polysaccharides.
