Abstract
The filling capacity of tobacco is improved by treating the tobacco with inert gas under pressure and subsequently heating after relieving the pressure. The tobacco is treated with nitrogen or argon at a working pressure between 300 and 1000 bar and working temperature in the range of 0.degree. to 50.degree. C. and after relieving the pressure then is treated briefly at a temperature of 100.degree. to 400.degree. C. or is subjected to microwave heating.
