ABSTRACT:
A method for uniformly impregnating tobacco with additives, particularly flavoring agents, is disclosed. The method comprises contacting tobacco with liquid carbon dioxide having dispersed therein a flavoring agent or other additive; exposing the liquid carbon dioxide absorbed by the tobacco to conditions whereby it is converted to solid carbon dioxide; and thereafter allowing the solid carbon dioxide to evaporate. When the solid carbon dioxide is caused to vaporize rapidly, for example, by means of heat, the disclosed method will simultaneously impregnate tobacco with an additive and expand tobacco.
