| Abstract:This study characterized the moisture absorption of slurry-type reconstituted tobacco sheets using the equilibrium moisture content， and explored the effects of added fiber beating degree， fiber types， tobacco powder particle size， and inorganic filler types on the moisture absorption of the reconstituted tobacco sheets using the method of controlled variables. The study also optimized the preparation process of slurry-type reconstituted tobacco sheets. The results showed that the effects of added fiber beating degree， fiber types， and tobacco powder particle size on the moisture absorption of reconstituted tobacco sheets were small. Among the 5 inorganic fillers， adding bentonite was found to be effective in reducing the equilibrium moisture content of reconstituted tobacco sheets and improving its moisture absorption. As the concentration of bentonite in the thick paste increased from 0 to 2.0%， the equilibrium moisture content of the reconstituted tobacco sheets decreased. When the dosage of bentonite in the thick paste was 1.5%， the equilibrium moisture content of the reconstituted tobacco sheets were 16.7%， 15.5%， and 13.5%， respectively lower than that of the original sheet （without bentonite） at the relative humidity of 50%， 60%， and 70%. The cigarette made by the reconstituted tobacco sheet had similar burning rate and fragrance to the original cigarette. |
