A method is described for extracting tobacco alkaloids from tobacco in which the tobacco alkaloids are extracted from the tobacco with carbon dioxide under supercritical conditions and the tobacco alkaloids separated from the carbon dioxide, wherein in the carbon dioxide for the extraction of the tobacco alkaloids from the tobacco is mixed with a solid 2 to 3-basic organic acid having a total of 2 to 6 carbon atoms, a monoalkali or monoammonium salts thereof in order to appreciably shorten the extraction times.

Method for extracting tobacco alkaloids

With the present invention a tobacco sheet or foil is proposed which has an elevated filling force and consists of tobacco particles, water, binders and moisturizers, and relatively gas-impermeable, in particular surface-sealed cover layers being connected together by a spongy structure which is formed by gas-filled bubbles, and in which cavities are formed having a shaggy, furrowed and/or torn surface.
