基于温湿度调制效应的烟叶烘烤工艺对烟叶质量的影响

Effects of Curing Temperature and Relative Humidity on the Quality of Flue-cured Tobacco Leaves

[目的]研究烤烟品种K326的最佳烘烤温度和湿度。[方法]在烟叶变黄阶段,考察不同温度和湿度条件下烟叶化学成分、石油醚提取物含量及香吃味。[结果]在烟叶烘烤的变黄阶段,温度保持在36℃,相对湿度保持在85%,可最大程度地促进烟叶烘烤中的化学成分的分解转化,提升烟叶品质,烟叶石油醚提取物含量最高(8.77%),香吃味得分最高(48.67分)。[结论]在该试验条件下,最佳烘烤条件是温度36℃、相对湿度控制在85%。

[Objective] The research aimed to study the optimum curing temperature and relative humidity for tobacco leaf K326.[Method] Chemical components,account of aroma and flavor and petroleum ether extract content were studied under different curing temperature and relative humidity during the yellow stage.[Result] The favor and smoking quality of cured tobacco leaves was high when the temperature curing process was 36 ℃ and relative humidity was 85%,and petroleum ether extracts content and the aroma and flavor score were 8.77% and 48.67,respectively,and both reached the highest.[Conclusion] Under the experimental conditions,the best curing condition was temperature 36 ℃,relative humidity85%.
