Abstract: The adsorption rates and desorption effects of different resins on Vaccinium corymbosum fruit pigment,as well as the elution effects of different eluents were studied,and then the extraction technology of pigment with resin from Vaccinium corymbosum fruit was determined. The properties of the pigment were analyzed as well.The results showed that D101-A resin has better adsorption and desorption effects on the pigment.100-min Elution with 60% ethanol is optimal for the pigment. The colority E(1% and 537 nm) of the product is 42,and its yield is 0.256%. After using D101-A resin for 20 times repeatedly,the absorption rate is only at a loss of 1.24%. The pigment has good water solubility and stability to acid solution(pH ≤4) ,light,hear(lower that 80℃) and low concentration food additives.

Key words: Vaccinium corymbosum, pigment, resin, extraction technology, physicochemical properties
