变黄阶段湿球温度对烤后烟叶质量及中性香气物质含量的影响

Effects of Wet Bulb Temperature at Yellowing Stage on Flue-cured Tobacco Quality and Neutral Aroma Matter Content

以中烟100为供试品种,研究了密集烘烤过程中变黄阶段湿球温度对烤后烟叶质量和中性香气物质含量的影响。结果表明:低湿球温度(35℃)条件下的烤后烟叶质量显著优于较高湿球温度(36℃)条件下的烤后烟叶,具体表现为色度强、挂灰杂色少、总糖和还原糖含量较高、含氮化合物含量较低、糖碱比和氮碱比适宜、中性香气物质含量高。

The effects of wet bulb temperature at yellowing stage on the quality of flue - cured tobacco and content of neutral aroma matter in the leaves of Zhongyan 100 were studied in this paper. The results showed that the quality of flue - cured tobacco was better in lower wet bulb temperature （35℃ ） environment than that in higher wet bulb temperature （36℃） environment, and it showed as stronger chromaticity, lesshang ash, higher total sugar and reducing sugar, lower nitrogen content, more appropriate ratios of sugar to al- kali and nitrogen to alkali, higher neutral aroma material content.
