Abstract:To explore the development and utilization value of anthocyanins in blueberry peel residues，the effects of extraction agent type and volume fraction，solid-liquid ratio，extraction frequency，and extraction time on the concentration of anthocyanins in the extraction solution were studied. Eight types of macroporous resins（X-5，XAD-16，DM-21，SP-207，LS-305，LS-610B，AB-8，and D101） were used to compare the adsorption and purification of the extraction solution. The results showed that the optimal extraction agent was a 60% ethanol aqueous solution，and the optimal extraction conditions were as follows：a solid-liquid ratio of 1∶4（g/mL），countercurrent extraction for three times，and extraction for 4 h each time. The study on resin purification showed that LS-305 had the best adsorption and desorption performance. After adsorption，the color value of the solid pigment product obtained after resin adsorption and purification increased by 3.1 times；the anthocyanin content increased by 4.6 times，and the yield decreased by 4.5 times. According to the different requirements of customers for products′ color value，different process flows were designed. For those who required a color value below 18，ethanol extraction，concentration，and drying process could be used. If products with high color values were required，adsorption columns could be used for purification.
