Abstract

The tobacco is impregnated with liquid carbon dioxide, then treated in order to convert the liquid carbon dioxide to solid carbon dioxide, and then expanded by evaporation of the solid carbon dioxide, the moisture content of the tobacco used, the pressure of the liquid carbon dioxide in the impregnation stage and the final humidity of the expanded tobacco being controlled relative to each other and excess liquid carbon dioxide being removed from the impregnated tobacco before the conversion to solid carbon dioxide. The method can be carried out simply and without expensive equipment, and permits a high degree of expansion without introducing foreign constituents into the tobacco and without influencing the flavour.
