Embodiment Construction

[0044]In one embodiment, dissolution of tobacco in an ionic liquid and regeneration of tobacco fibers from the ionic liquid is performed. It is understood that other ionic liquids and conditions can be used to dissolve tobacco and other methods for regeneration can also be used. In this example, tobacco shreds were suspended in 1-ethyl-3-methylimidazolium acetate (several shreds per milliliter) and heated slightly by a heat gun. Within 30 minutes, the tobacco shreds were completely dissolved in the liquid. A drop of tobacco dissolved in ionic liquid was dropped on a glass slide, and a drop of water was added to the slide, tobacco fiber regrowth was observed at the water / ionic liquid boundary.

[0045] In another experiment, reducing sugars were extracted from a liquid tobacco composition (tobacco shreds dissolved in 1-ethyl-3-methylimidazolium acetate) or undissolved tobacco shreds using an acetic acid solution. The reducing sugar extracted from the acetic acid solution reac...

Abstract

A liquid tobacco composition comprising tobacco dissolved in an ionic liquid. Removal of selected tobacco components is assisted by dissolving the tobacco in an ionic liquid. Tobacco from which selected components have been removed can be regenerated from the liquid tobacco composition by separating the tobacco and the ionic liquid.

Description

technical field [0001] The present disclosure relates to liquefied tobacco, and more particularly to tobacco dissolved in an ionic liquid and the regeneration of liquefied tobacco into a solid tobacco product. Background technique [0002] Extensive research has been conducted on tobacco and tobacco components. It has been established in many instances that it is desirable to reduce the levels of certain components, such as tobacco-specific nitrosamines, in the final tobacco product. Current methods of reducing the level of such components in tobacco involve extracting the component from the tobacco by incubating the tobacco with a solvent in which the component is soluble. But this method tends to be less efficient, at least in part because of poor penetration of the solvent into the tobacco or incomplete extraction of components bound to insoluble parts of the tobacco, such as cellulose. More efficient removal of components of tobacco, such as tobacco-specific nitrosamin...
