乙醇提取辣味鸡油中辣椒素工艺

以工业生产盐焗鸡的副产物--辣味鸡油为原料，研究乙醇提取辣椒素工艺。结果表明：辣椒素的最佳提取条件为以95%乙醇作为提取溶剂，70℃提取3h，料液比1:3(g/mL)；一次提取的提取率可达51.44%，一次提取无法将辣味鸡油中的辣椒素提取完全，需要经过多次提取。通过方差分析，对提取率影响因素从大到小依次为：乙醇体积分数＞温度＞时间＞料液比。

Extraction of Capsaicin from Spicy Chicken Oil Using Ethanol

The extraction process of capsaicin from spicy chicken oil,as an industrial salted chicken by-product,was explored in this paper.The results showed that the optimal extraction process conditions were ethanol concentration of 95%,extraction temperature of 70 ℃,extraction time of 3 h and material-liquid ratio of 1:3(g/mL).Under the optimal extraction process,the extraction rate of capsaicin could reach up to 51.44%.Through the analysis of variance,the factors for extraction rate from strong to weak order were ethanol concentration,extraction temperature,extraction time and material-liquid ratio.
