摘要
目的探索有机溶剂提取辣椒红色素新的工艺条件,以获得高色价的辣椒红色素。方法先用有机溶剂浸提粉碎的干辣椒粉;然后皂化处理浸提物,比较辣椒红色素在不同温度、时间、溶剂浓度下提取的效果;最后用硅胶柱层析进行精制分离。结果确定了皂化的最佳条件是:提取的有机溶剂为10%NaOH醇溶液,70℃下皂化4 h可有效除去辣椒红色素粗品中的杂质,经过硅胶柱层析精制分离,可得到色价大于600的辣椒红色素。结论在提取辣椒红色素的工艺中,皂化前处理对提高色价有很好的效果。
Objective To explore a new processing method for organic solvent extraction of capsanthin in order to obtain capsanthin with a high color scale value. Methods Firstly, red chilli powder was soaked with organic solvent, then the extract was saponified under different conditions scheduled by temperature, time and solvent content to obtain crude capsanthin which was refined by silica gel chromatography. Results The optimal saponification condition was as follows： 10% NaOH alcoholic solution as organic solvent, 70℃ for 4 hours. The capsanthin with a high color scale value （E 〉 600） could be gained from the refining of crude capsanthin. Conclusion The pre-saponification is good for obtaining capsanthin with high quality from red chillies.
