摘要
紫玉米中含有丰富的花青素,是具有抗氧化作用的一种天然色素。通过正交试验得到最佳提取工艺:以80%乙醇与0.2mol/L柠檬酸混合物为提取剂,料液比为1∶10(w/v),60℃下提取2h,提取两次。该色素是一种应用前景广阔的天然食用色素。
Purple corns contains rich anthocyanin pigments. In this paper, the effect of four factors on extraction of pigment with orthogonal design test was investigated. The optimum condition was that, the extractive reagent was mixture of 80% alcohol and 0.2mol/L citric acid, the weight of mixture was 10 times of the purple corn, the purple corn was extracted 2 times at 60℃, each step for 2h.
