摘要
研究了辣椒中活性成分辣椒素的最佳提取工艺条件。在单因素试验的基础上,用正交试验法对辣椒素的提取工艺进行优选,选用L9(34)进行正交试验,以辣椒素的得率为指标,考察乙醇浓度、提取温度、提取时间以及料液比对辣椒素提取的影响。得到的最佳工艺条件为:温度70℃,时间0.5h,提取溶剂为70%的乙醇,料液比(质量∶体积)1∶10,提取次数3次。
The optimum process of extracting capsaicin,the bioactive component in paprika( Capsicum annuum L.) was studied.The optimum extraction process was optimized with orthogonal test.Experiments were made by using L_9(3 4) orthogonal design with extractive yield of capsaicin as the index,investigating the influence of ethanol concentration,temperature,extracting time and the ratio of solid to liquid.Optimum extraction conditions were determined as follows:temperature 70 ℃,time 0.5 h,70 % EtOH as extracting solvent,stock ratio 1∶10(mass∶volume),extracting for three times.
