摘　　要：以红辣椒为原料,采用索氏提取+超临界萃取和二次超临界萃取法,对两种方法得到的辣椒油树脂、辣椒红色素进行了色价、产率、辣椒素含量的分析比对,并对色素的质量进行检测.结果表明,生产辣椒红色素,索氏提取+超临界萃取是比较好的方法,成本低,所得色素质量也不错;二次超临界萃取的方法,中间产物辣椒油树脂的色价和辣椒素含量比较高.Using red peppers as raw materials,to extract capsaicinoids by the methods of soxhlet extraction and supercritical fluid extraction and supercritical fluid extraction and supercritical fluid extraction, then analysed and compared on the color value,yield and the percentage of capsaicinoids content of the capsicum oleoresin and capsicum red pigment,which were made by the two methods, and detect the quality of pigment. Results show when produce capsicum red pigment, soxhlet extraction and supercritical fluid extraction is a good method for its low cost and good quality of pigment; using the method of supercritical fluid extraction and supercritical fluid extraction,The color value of capsicum oleoresin and the percentage of capsaicinoids content of the intermediate are higher.
