Abstract: To further deepen the understanding of physical modified atmosphere method, the effect of controlled atmosphere and varying pattern of alcoholization quality of the flue-cured tobacco lamina were researched. The results proved that: physical modified atmosphere method could keep stable oxygen concentration within fitting zone for the alcoholization of the flue-cured tobacco lamina. Using the method of physical modified atmosphere, the sensitivity between stacking internal relative humidity and the outside humidity was low, the flue-cured tobacco lamina was in favor of preventing be affected with damp and mildew under high humidity conditions. After 12 months of alcoholization, compared with chemical modified atmosphere method, the aroma precursors material of the physical modified atmosphere method such as chlorogenic acid, rutin, lutein and β-carotene degradation was more fully, the alcoholization quality of the flue-cured tobacco lamina had certain degree of ascension. The sensory quality of the flue-cured tobacco lamina was best with the treatment of the oxygen concentration call backed to 15%-21%. The alcoholization quality of the flue-cured tobacco lamina of physical modified atmosphere method was better than the chemical modified atmosphere method.
