摘　　要：本研究对黑芸豆的花色苷色素提取工艺进行研究。将黑芸豆放在不同乙醇浓度、不同温度、不同时间、不同盐酸浓度、不同料液比的条件下,进行5类单因素试验,并通过L16(45)正交表进行5因素4水平优化试验,确定黑芸豆中花色苷提取率最佳工艺。结果表明:乙醇浓度70%、料液比1∶20、提取温度50℃、提取时间45 min、0.5%HCl溶液为最佳提取工艺。This paper studied the extraction of anthocyanin pigment from black kidney bean.By different types of ethanol concentration, temperature,time and soaking liquid,5 types of the single factors and L16（4 ^5）orthogonal design were done to study the best range of extracting.The results showed that the optimum conditions were as follows： 70% ethanol concentration and 0.5% hydrochloric acid as soaking liquid,rate of solid 1：20, temperature 50 ℃ ,time 45 min.
