【摘要】 研究了用于苹果汁吸附实验的不溶性壳聚糖的制备工艺。不溶性壳聚糖的制备工艺条件为:脱乙酰处理时NaOH的质量分数为35%、50℃、6h。对不溶性壳聚糖的吸附性能、再生性能和质量标准进行了研究,制备的不溶性壳聚糖符合国家标准的要求,可以多次再生使用,不易造成二次污染,且具有良好的机械强度,适合用做苹果汁脱色和澄清的吸附材料。更多还原

【Abstract】 Preparation technology of insoluble chitosan was studied that was designed for adsorption of apple juice.The best preparation conditions for the insoluble chitosan were 35% NaOH,50℃,and 6h.Its adsorptive and regeneration properties were investigated.The prepared insoluble chitosan could be regenerated and be suitable for acting as adsorbents for decolorization and clarification of juice.更多还原
