摘要
以去离子水为溶剂,利用提取法从肇庆皇帝柑果皮中提取黄色素,通过正交实验优化提取的工艺条件,优化结果如下:浸提温度为70℃,料液比为1:30,浸提时间为2 h.稳定性研究表明:加热、光照、氧化剂、还原剂对皇帝柑果皮黄色素稳定性的影响不大,p H值对其的影响则较为明显;Fe3+会使黄色素提取液产生绿蓝色沉淀,Cu2+和K+对黄色素提取液的稳定性有一定影响,而Ca2+,Mn2+,Mg2+和Zn2+则不产生影响.
The research of extraction and the stability of yellow pigment from tangerine peel were studied in the paper. The results of orthogonal experiment showed that the optimization conditions of extraction are as be- low： the ratio of emperor tangerine peel to solvent is 1：30, the extraction time is 2 h, and the temperature is 70 ℃. The resreach of stability revealed light, heat, oxidant agent, reducing agent and some metal ions such as Ca^2＋,Mn^2＋,Mg^2＋,Zn^2＋ cause little impact to the yellow pigment extracted from emperor tangerine peel, but the influ- ence ofpH, Cu^2＋ and K^＋ on the yellow pigment solution cannot be ignored. In particular＂, adding Fe^3＋ to the yellow pigment solution give a precipitate.
