ABSTRACT:
The invention is directed to a process for expanding tobacco wherein tobacco is impregnated with gaseous 1,1,1,2-tetrafluoroethane and thereafter heated in an expansion zone to liberate the 1,1,1,2-tetrafluoroethane and cause expansion of the tobacco. The process of the invention can provide substantial expansion of tobacco cut filler lamina without substantial generation of tobacco fines and employing substantially mild pressures of, for example, less than about 3,000 psi and with minimal effect on tobacco flavor.
