Abstract
The impairment of the taste of smoke, observed in processes for improving the filling capacity of tobacco by expansion of the tobacco with a vaporizable expanding agent, can be avoided if an anti-oxidant, in particular ascorbic acid, is added to the tobacco before the expansion. In addition, anti-oxidant synergists can also be added.
