Abstract: For optimizing the technics of storing cut tobacco in cases,the traditional means of case filling by compressing was compared with filling by suction in terms of the physical index of packed cut tobacco and the smoke index and sensory quality of cigarette.The results showed that:1) Comparing with traditional compressing means,the suction means produced lower tobacco breakage,did not affect cut tobacco structure obviously during storage,and the reduction of long strands portion was less than 0.24%.2) With the prolongation of storage time,the moisture content changed a little in cut tobacco packed by either means,the filling power of cut tobacco decreased slightly,however,the filling power of cut tobacco packed by suction means was always higher than that by compressing means.3) For cut tobacco packed by suction means,storage time basically did not affect smoke index,the results of sensory evaluation indicated that there was no obvious sensory quality difference between the test samples stored for 9 days and the control.
