摘　　要：为了快速准确地判断辣椒成熟度,用近红外光谱仪研究量化检测辣椒的成熟度。该研究利用近红外技术对34个辣椒品种的成熟度进行光谱分析,并将所得的数据与辣椒组分测定值进行关联。结果表明:所得辣椒素、蛋白质、维生素C、纤维素、总酸5种辣椒组分近红外模型的相关系数r依次为0.7760、0.9028、0.2745、0.8056、0.8481,校正标准偏差(校正集的预测均方差)RMSEC依次为0.116、0.137、38.5、5.16、0.469;辣椒的蛋白质含量近红外模型的相关性最高,其RMSEC为0.137,比其余4种组分模型更准确。该模型可以高效检测辣椒成熟度,为合理安排辣椒采收期提供依据。In order to judge the maturity of hot pepper quickly and accurately,the near infrared quantization method was used to detect the maturity of hot pepper.In this study,the mature samples of 34 pepper varieties were analyzed by near-infrared technology,and the data were correlated with the measured values of pepper components.The results show that the correlation coefficients of capsaicin,protein,vitamin C,cellulose and total acid are 0.7760,0.9028,0.2745,0.8056 and 0.8481,respectively.The root mean square error of calibration(RMSEC)are 0.116,0.137,38.5,5.16 and 0.469,respectively;The near infrared model of pepper protein content has the highest correlation,and its RMSEC of 0.137 is more accurate than the other four components model.Therefore,the model can efficiently detect the maturity of hot pepper and provide a basis for reasonable arrangement of pepper harvest time.
