摘　　要：辣椒中的辣椒素类物质是引起人痛感的主要物质,检测此类物质精准性高的方法为高效液相色谱法,但此检测方法存在样品处理和目标物质提取繁琐且耗费时长的问题,不能快速检测辣椒素类物质含量。文章通过采用手持式近红外光谱仪,对干辣椒的辣椒素类物质进行扫描,获取辣椒素类物质的图谱,同时结合高效液相色谱仪检测得到辣椒素物质含量结果,建立辣椒素类物质含量测定模型。结果表明:建立的小椒模型其预测值的准率为90%,建立的艳椒模型其预测值的准确率为95%。采用获得的模型对干辣椒的辣椒素类物质检测,能够快速获取干辣椒的辣椒素类物质含量,从而达到快速检测目的。The capsaicin like substances in chili peppers are the main substances that cause pain,and the highly accurate method for detecting such substances is high-performance liquid chromatography.However,this detection method has the problems of tedious sample processing and time-consuming extraction of target substances,and cannot quickly detect the content of capsaicin like substances.This article uses a handheld near-infrared spectrometer to scan the capsaicin like substances in dried chili peppers,obtaining a spectrum of capsaicin like substances.At the same time,combined with highperformance liquid chromatography to detect the capsaicin content results,a capsaicin content determination model is established.The results show that the accuracy of the predicted values of the established Xiao Jiao model is 90%,and the accuracy of the predicted values of the established Yan Jiao model is 95%.The use of the obtained model for the detection of capsaicin like substances in dried chili peppers can quickly obtain the capsaicin like substance content of dried chili peppers,thereby achieving the goal of rapid detection.
