辣椒红色素的提取与分离

利用索氏提取法,用不同溶剂从几种辣椒中提取辣椒红色素和辣椒素,确定了较佳提取工艺条件;利用树脂吸附法和溶剂萃取法分离色素和辣椒素,确定了较佳洗脱剂和萃取分离条件.试验结果表明,小米椒辣椒红色素含量最高,用氯仿提取效果较好,较佳提取时间为50 min;XAD16树脂可吸附无水乙醇溶解的红色素,其饱和吸附为每g树脂可吸附0.017 g辣椒提取物中的色素,氯仿为较佳洗脱剂;溶剂萃取分离辣椒红色素的较佳条件为:80%乙醇,萃取3次,萃取时间60min.另外,弱碱性金属氧化物有很好的除辣效果.

Extraction and Seperation of Capsanthin from Chilli

Capsanthin and capsaicine were extracted from several different chili using Soxhlet extraction,and the optimum extraction condition were studied.The resine adsorption and solvent liquid extracting were used to separate the capsanthin from capsaicine.The results showed that the content of red pigment in Millet pepper was the highest,the optimal extraction solvent was chloroform,and extraction time was 50 min.XAD16 adsorption resin could adsorb capsanthin dissolved in ethanol,the saturation adsorption of 1 g resin was 0.017 g capsanthin.The optimum extracting conditions of capsanthin were as follows: 80% ethanol,3 times extraction,extraction for 60 min.In addition,alkalescence metal oxid could eliminate capsaicin very well.
