Abstract:

The paper aims to further improve the quality of stored tobacco aging, and to provide technical support for the scientific management of aging tobacco. The effects of different packing densities (100, 150 and 200 kg/0.593 m3) on the chemical composition, usability, and sensory quality of flue-cured tobacco lamina were investigated to improve the alcoholization efficiency and rate of tobacco lamina during storage life by comprehensive evaluation method of chemical composition usability. The results showed that for both the tobacco grades (B3F and C3F), the moisture content of tobacco lamina samples with the packing density of 100 kg/0.593 m3fluctuated most dynamically with time. The usability of main chemical components in tobacco lamina samples was relatively high when the packing density was 150 kg/0.593 m3. In all cases, the sensory quality of tobacco lamina samples changed in a parabolic trend as the duration of alcoholization increased. The total sensory quality scores obtained within an appropriate alcoholization period were ranked in the order: 150 kg/0.593 m3>100 kg/0.593 m3> 200 kg/0.593 m3. In conclusion, the overall quality of tobacco lamina is optimal after alcoholization with a packing density of 150 kg/0.593 m3.

Key words: packing density, tobacco strips, alcoholization quality, chemical usability, sensory qualities
