| Abstract:In order to investigate the moisture absorption characteristics of heated cigarette， the changes law of area， thickness and cigarette circumference with equilibrium humidity of two kinds of tobacco sheet in heated cigarette prepared by thick pulp method and paper spraying method， respectively， were studied by chemical analysis， image analysis technology and sensory quality evaluation. The results showed that the area， thickness of tobacco sheet and cigarette circumference increased with the increase of equilibrium humidity， and the increase of cigarette circumference was positively correlated with the increase of tobacco sheet thickness. Affected by the influence of the preparation technology， the increasing range of area and thickness of tobacco sheet prepared by thick pulp method were larger than that by paper spraying method. The increase of thick pulp method tobacco sheet’s area was mainly due to the increase of longitudinal length， and the increase of thickness was due to the volume swelling of loose part after absorbing water. The moisture content of tobacco sheet increased with the increase of equilibrium humidity， which in turn affected the sensory quality. The change of sensory quality was reflected in the increase of oral burning sensation with the increase of equilibrium humidity. When the equilibrium humidity was between 40%~50%， the stability of the indexes of tobacco sheet and cigarette were good， which was beneficial to the storage of tobacco sheet and cigarette. |
