摘要
黑糯米中含有丰富的黑色素。本文研究了不同方法提取黑糯米中的黑色素，以及AB-8树脂吸附和分离黑糯米黑色素，比较了四种树脂对黑糯米黑色素的吸附。选用AB-8树脂作吸附剂，洗脱剂用80%的乙醇，产品质量较好，色价高， AB-8树脂非常稳定，使用18次后，其吸附率仅降低4.67%。
the different ways of extraction of sticky rice black pigment were studied. We compared the four resins. The results showed that AB-8 resin had the best performance of absorption on sticky rice black pigment. In the course of desorbing the absorbed sticky rice pigment with 80% ethanol, AB-8resin showed a fairly good character of stabilization. After using the resin 18 times, the absorption factor was decreased by nearly 4.67%.
