摘　　要：采用三速和单速循环风机,研究密集烤房不同循环风机对烤烟色素及感官质量的影响。结果表明:采用三速循环风机烤后烟叶的叶绿素a、叶绿素b含量分别为5.10、167.74μg/g,分别为单速循环风机的72.11%和93.30%;叶黄素、β-胡萝卜素、类胡萝卜素含量分别为0.84、155.56、156.40μg/g,分别为单速循环风机的86.40%、95.53%和95.47%;采用三速循环风机与单速循环风机的烤后烟叶中叶绿素a、叶绿素b和叶绿素a与叶绿素b含量比差异显著,β-胡萝卜素和类胡萝卜素含量差异极显著,叶黄素和类叶比差异不显著;采用三速循环风机烤后烟叶的感官质量总体优于单速循环风机。The degradation of pigment and the change of smoking quality of flue-cured tobacco caused by the curing process were studied by using different circulating ventilators and the according curing-procedures. The results indicated that chlorophyll a and chlorophyll b contents in the three-speed circulating ventilator treatment were 5.10 μg/g and 167.74 μg/g, which were 92.49% and 95.47% of that of the single-speed treatment while Lutein, β-carotene and carotenoid content were 0.84, 155.56 and 156.40 μg/g, which were 86.40%, 95.53% and 95.47% of that in the single-speed treatment. There were significant differences in Chlorophyll a, chlorophyll b and chlorophyll a/b contens in cured leaf between the two ventilator treatments. The difference was extremely significant in β-carotene and carotenoid. There was no obvious difference in lutein and Car/Chl. The smoking quality of the three-speed circulating ventilator treatment was better than the single-speed treatment.
