摘要:
以番薯叶为原料，采用超声波辅助提取精制多糖，通过高岭土、活性炭、过氧化氢设置各个量进行脱色反应，以及采用分光光度法测定脱色后的吸光度，计算脱色率。研究结果表明番薯叶在高岭土、活性炭、过氧化氢溶液中，在适宜条件下均有较好的脱色效果，其中，活性炭的脱色效果最好。
With sweet potato leaves as raw material, the ultrasonic assisted extraction has been used to refine polysaccharide through setting the kaolin clay, activated carbon and hydrogen peroxide amount to carry on the decolorizing reaction, using spectrophotometry after decolorizing absorbance, and decoloring rate calculation. Some research results show that the sweet potato leaves have good decolorization effect in kaolin clay, activated carbon, hydrogen peroxide solution, under appropriate conditions.
