摘要
本文采用正交实验法优化了姜黄色素的提取工艺。选取乙醇和丙酮为提取剂,探讨在温度为55℃条件下提取液浓度、料液比、提取时间对姜黄素提取率的影响。通过L9(34)正交试验,提取姜黄素的最佳工艺条件:乙醇提取浓度为75%,物料比为1∶10,提取时间为2.5h,提取率为4.48%;丙酮提取浓度为70%,物料比为1∶20,提取时间为2h,提取率为4.94%。丙酮对姜黄素的提取率比乙醇高,时间短,但提取液使用量大,该实验结果为工业上提取姜黄素有一定的参考价值。
In this paper, we studied on orthogonal extraction technology of curcumin pigment. When temperature was 55℃, the influence of the material liquid extract concentration, solid-liquid ratio, and extraction time on cureumin extraction rate were explored. Through orthogonal test L9 （3^4）, the optimum extracted process conditions of cureumin were that： ethanol concentration for 75%, materials for 1：10, and extracting time than for 2.5h, extraction rate 4.48%. Acetone concentration as 70%, materials, than for extracting time for 2h as extraction rate was 4.94%. Ace- tone extraction of curcumin was higher than ethanol, and extraction time was shorter., Extract usage of acetone was larger. The experimental results provided a reference for industrial extraction of curcumin.
