The invention relates to a flavoring agent containing tobacco and consisting of such tobacco Tobacco products.

It is known that by adding flavorings to tobacco gives the Tebakraueh a pleasant aroma can be. In known processes, the tobacco was impregnated with a solution of the aroma toffee for this purpose or the solution of the flavoring on the tobacco sprayed on »A disadvantage of this method is that most of the aroma coffees suitable for this at normal room temperature leioht volatilize and desecrate "

The object of the invention is therefore the premature Prevent loss of volatile flavors from tobacco *

These are, for example, methanol, Llraone, lemon, peach, pineapple, cherry, spermint, pepper:. "- ainz and cola in the form of natural oils or as one Inert oil suspended small particles.
