摘要: 为探索不同变黄方式对烤烟品质的影响,明确较适宜的烤烟变黄方式,采用烘烤试验的方式研究阶段降低湿球、胁迫失水变黄、中温中湿和高温保湿4种变黄方式对烤后烟叶品质的影响,对烤后烟叶外观颜色指标、感官质量、酚类物质、常规化学成分、游离氨基酸和有机酸含量等指标进行了测定,并采用偏最小二乘判别法(Partial least squares‐discrimination analysis,PLS‐DA)对试验结果进行综合分析。结果表明,相较于其他处理,胁迫失水变黄处理的烤后烟颜色最接近国际色卡橘黄色的色度标准,香气特征、烟气特征、口感特性较优,综合感官品质得分最高(68.18);胁迫失水变黄处理烤后烟的绿原酸、芸香苷、烟碱、总氮、钾和脯氨酸含量最高。PLS-DA分析结果显示,4种变黄方式下,烟叶品质存在明显差异;烟碱、脯氨酸、绿原酸的变量投影重要性(Variable importance in the projection,VIP)较高,可作为提升烟叶烘烤质量的关键指标。

Abstract: This research aims to study the effects of different yellowing methods on the quality of flue‐cured tobacco,and to clarify the appropriate yellowing method for flue‐cured tobacco.The effects of four types of yellowing methods,stage reduction of wet bulb,stress dehydration yellowing,medium temperature and medium humidity and high temperature moisturizing on the quality of flue‐cured tobacco leaves were determined,including the appearance and color,sensory quality,phenolic content,conventional chemical composition,free amino acid content and organic acid content. The partial least squares‐discrimination analysis(PLS‐DA)was used to comprehensively analyze the experiment results.Research indicated that,compared with other treatments,the color of flue‐cured tobacco treated with stress dehydration yellowing was the closest to the international orange color standard with better aroma characteristics,smoke characteristics,taste characteristics,and had the highest comprehensive sensory quality score(68.18).In addition,the content of chlorogenic acid,rutin,nicotine,total nitrogen,potassium and proline of flue‐cured tobacco after the treatment of stress dehydration yellowing was the highest compared with other treatments. The PLS‐DA results showed that there were significant differences in the quality of tobacco leaves under the four yellowing methods,and nicotine,proline,and chlorogenic acid had higher variable importance in the projection(VIP),which could be used to improve tobacco quality as the key indicators of curing.
