During storage, the quality of tobaccos will deteriorate due to environmental conditions such as relative humidity and temperature. This work determined the desirable tobacco packing density, wrapping materials and shelf-life required to maintain both the initial tobacco moisture and quality attributes such as taste and flavor. Relative humidity and temperature affected the tobacco equilibrium moisture level. It was found that to control tobacco moisture at 13%, optimum packing densities for cut tobacco and expanded tobacco were 200 and 120 Kg/m3, respectively. Cut tobaccos stored for 35 days in various wrapping materials at 90% RH and 30.degree.C were found to increase moisture. With a series of polyethylene films, the moisture increased from 11.35% to 12.94-15.74%. With a kraft paper wrapping, the tobacco moisture increased from 11.35% to 23.41%. It is concluded that to maintain tobacco moisture and quality during storage, a 110micron polyethylene film wrap is needed. With this wrapping, the shelf-life of cut tobacco was found to be 42 days (90% R.H. and 30.degree.C).
