摘　　要：为实现烘烤过程中烟叶不同区段质体色素及颜色的在线监测,为烟叶不同区段加工及实现智能烘烤提供参考,采用色度信号监测设备、丙酮-分光光度计比色法和色差仪等分别测定烘烤过程中关键温度点烟叶不同区段的色度信号值、色素含量和颜色参数,并分析其变化规律,借助相关性分析和回归分析方法分析色度信号值、色素、颜色参数之间的相关性,构建色度信号值与色素之间的回归方程,并进行验证。结果表明,烘烤过程中鲜烟叶不同区段叶绿素、类胡萝卜素含量存在明显差异,表现为叶基>叶中>叶尖。相关性分析结果表明,烟叶不同区段亮度值(L^(*))、红度值(a^(*))、黄度值(b^(*))与叶绿素a、叶绿素b、叶绿素、类胡萝卜素含量均呈极显著负相关关系;不同区段色度信号值与亮度值(L^(*))、红度值(a^(*))、黄度值(b^(*))均呈极显著正相关关系,与叶绿素a、叶绿素b、叶绿素、类胡萝卜素含量均呈极显著负相关关系。回归分析结果表明,不同区段烟叶色度信号值与叶绿素a、叶绿素b、叶绿素、类胡萝卜素含量拟合度较高;回归方程验证结果表明,叶基叶绿素a、叶绿素b、叶绿素、类胡萝卜素含量相对误差分别为8.19%、9.13%、8.42%、13.58%,叶中叶绿素a、叶绿素b、叶绿素、类胡萝卜素含量相对误差分别为11.39%、6.63%、10.42%、7.63%,叶尖叶绿素a、叶绿素b、叶绿素、类胡萝卜素含量相对误差分别为11.47%、10.79%、10.21%、11.58%。综上,色度信号检测设备试验误差小、自动化程度高、准确度高,能够实现对烘烤过程中不同区段烟叶质体色素的快速精准监测。In order to achieve online monitoring of plastid pigments and colors in different sections of tobacco leaves during the baking process,and provide reference for the processing of different sections of tobacco leaves and the realization of intelligent baking,technologies such as chromaticity signal monitoring equipment,acetone spectrophotometer colorimetric method,and colorimeter were used to measure the chromaticity signal values,pigment content,and color parameters of different sections of tobacco leaves at key temperature points during the baking process,and analyze their changes.Correlation analysis and regression analysis methods were used to analyze the correlation between chromaticity signal values,pigments,and color parameters,and regression equations between chromaticity signal values and pigments were constructed and verified.The results showed that there were significant differences in the content of chlorophyll and carotenoids in different sections of fresh tobacco leaves during the baking process,manifested as leaf base>leaf middle>leaf tip.The correlation analysis results showed that the brightness value(L^(*)),redness value(a^(*)),and yellowness value(b^(*))of different sections of tobacco were significantly negatively correlated with the content of chlorophyll a,chlorophyll b,chlorophyll,and carotenoids;The chromaticity signal values in different sections were significantly positively correlated with brightness value(L^(*)),redness value(a^(*)),and yellowness value(b^(*)),and significantly negatively correlated with chlorophyll a,chlorophyll b,chlorophyll,and carotenoid content.The regression analysis results indicated that the chromaticity signal values of tobacco leaves in different sections had a high degree of fit with chlorophyll a,chlorophyll b,chlorophyll,and carotenoid content;The regression equation validation results showed that the relative errors of chlorophyll a,chlorophyll b,chlorophyll,and carotenoid content in the leaf base were 8.19%,9.13%,8.42%,and 13.58%,respectively.The relative
