Abstract: 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%.
