以辣椒精为原料,研究不同辅助提取法对辣椒碱提取产量的影响,得出超声辅助法最优方案。通过单因素和正交试验确定辣椒碱提取的最佳工艺参数组合:以pH8的70%的乙醇作为溶剂,提取温度50℃,料液比1∶20,提取时间100 min,提取2次。 Taking pepper essence as raw material, the effects of different auxiliary extraction methods on the yield of capsaicin were studied, and the optimal ultrasonic assisted method was obtained. The optimum technical parameters of capsaicin extraction were determined by single factor and orthogonal experiments. The extraction process was as follows: 70% ethanol at pH8 was used as the solvent, the extraction temperature was 50 ℃, the solid-liquid ratio was 1:20 and the extraction time was 100 min.
