| 摘 要： | 目的研究蓝靛果红色素提取工艺及稳定性．方法采用超声波辅助乙醇法及正交试验确定蓝靛果天然红色素的最佳提取条件．结果与结论60％乙醇溶液作为提取剂，物料比为1：10，提取时间2h，提取温度30℃．与传统乙醇浸提法相比，在此条件下提取率从91．4％提升到95．1％，精制后的色素色价提高了10倍．蓝靛果天然红色素的稳定性实验表明：该色素溶液在强光、高热、氧化剂和高浓度还原剂的条件下不稳定，但在室温、低浓度的还原剂下较稳定．

| Abstract: | Objective To research the extraction and stability of pigment form Lonicera edulis. Method Using ultrasound-assisted ethanol extraction method. The extraction technology was optimized by using orthogonal test. Conclusion and Results 60% ethanol solution as extraction agent, material to extraction solution 1： 10, extraction time 2 hours, temperature 30℃. Compared with the traditional ethanol extraction method, the extraction rate of Lonicera edulis pigment increased from 91.4% to 95.1% by this method, but the extraction time is shortened. The purified pigment color enhanced 10 times. The solution of Lonicera edulis pigment was unstable to sunlight, heat, oxidant. But it was relatively stable to room temperature and low concentration. |
