摘要 [目的]研究不同干筋温度对烟叶烤后质量的影响，为确定不同部位烟叶最佳干筋温度提供理论依据。[方法]以翠碧1号品种为材料，通过设置4个不同干筋温度处理，研究不同处理对下、中、上部位烟叶外观及内在品质的影响。[结果]干筋阶段最高干球温湿度对烤后烟叶的外观质量和内在品质有较大影响，中下部烟叶干筋期最高温度64 ℃，上部叶68 ℃，烤后烟叶颜色光泽鲜亮，物理特性好，烟叶的外观等级质量较好，化学成分协调性和感官评吸质量改善效果较为突出。[结论]适当降低烟叶干筋期最高温度对提高烤后烟叶工业可用性较为有利。

Abstract [Objective] To study the effect of different stem drying temperature on baking quality of tobacco leaf， and to provide theoretical basis for determining the optimum temperature of different parts of tobacco leaf. [Method] With Cuibi 1 as the material， the effects of different treatments on the appearance and intrinsic quality of the lower， middle and upper tobacco were studied by setting four stem drying temperature. [Result] The maximum dry bulb temperature and humidity had a great influence on the appearance quality and intrinsic quality of the flue-cured tobacco leaves. The highest temperature of the middle and lower tobacco leaves was 64 ℃， the upper leaves were 68 ℃， the color of flue-cured tobacco leaf was bright and physical properties were good， the appearance quality of tobacco leaves was better， the chemical composition coordination and sensory evaluation quality improvement effect was more prominent. [Conclusion] It is more beneficial to improve the industrial availability of tobacco leaves after appropriate reduction of the maximum temperature of dry season.

干筋階段是排除烟叶主脉水分的时期，此阶段主要是蒸发散失烟筋水分使之干燥的过程，该阶段干球温度的高低对烟叶香气质量和香吃味的影响较为突出[1]。由于许多香气物质沸点较低，具有热不稳定性，因此，该时期温度不宜过高，否则易出现一些香气成分的挥发损失和烟叶烤红现象。研究发现，干筋期的温度范围一般在55～68 ℃，干筋期温度超过71 ℃会引起糖分焦化[2]，适当降低最高干筋温度有利于烟叶香气净化，减少有益香气挥发[3]，但温度过低，烟叶不易烤干，耗能较多。有关温、湿度对烟叶生理生化特性及烤后烟叶品质的影响已有研究[2-11]，但多集中在烘烤过程的变黄和定色阶段。关于不同最高干筋温湿度对烟叶内在品质及烟叶香气质量关系的研究目前鲜见报道。……
