摘要
应用正交设计研究千日红色素的提取工艺,以千日红色素溶液的吸光度为考察指标,讨论浸提剂、温度、时间、pH值、物料比对千日红色素提取的影响。结果表明:千日红色素提取的最佳条件:提取温度为40℃、提取溶剂蒸馏水的pH值为5、提取时间为5h。
The extractive technique of globeamaranth pigment were studied by the orthogonal experimental design as guided by the absorbency of solution of globeamaranth pigment.The effects of soak extraction solution,temperature,time,pH value,material-solution ratio on the extraction from globeamaranth pigment are also discussed.The results of the experiment shows that the optimum extractive conditions of the extraction from globeamaranth pigment were A3B3C2,namely,the extractive temperature 40 ℃,pH value of extractive solvent of the distilled water 5,time 5 h.
