Effects of Vacuum Conditioning on Sensory Quality of Flue-cured Tobacco Leaf

In order to investigate the effects of vacuum conditioning on the sensory quality of flue-cured tobacco leaf,the sensory quality of flue-cured tobacco leaf under different processing intensities in vacuum conditioning was compared.The results showed that:1) the aroma style of leaf changed at a rate increased with the increase of processing intensity when the leaf was treated by higher than moderate intensity;2) the effects of vacuum conditioning were stronger on the offensive taste,aroma quality and smoke smoothness than on the irritation,smoke cleanness,aroma quantity,dryness,concentration and strength;3) the aroma quality,offensive odor and smoothness of leaf could be improved by vacuum conditioning within a proper range of processing intensity.
