Molecularly imprinted polymers for treating tobacco material
United States Patent 9192193
Publication date: Nov. 24, 2015
Assignee: R.J. Reynolds Tobacco Company

This invention provides a method of extracting and isolating various compounds from plants of the Nicotiana species. It involves contacting a tobacco material with a molecularly imprinted polymer or a non-imprinted polymer specific to a target compound within the tobacco material for a sufficient time to bind the compound within the polymer.

In certain embodiments, the method is selective for compounds that are advantageously isolated and concentrated; e.g., organoleptic compounds known to impart flavor, texture and/or aroma to smoking articles and smokeless tobacco products. The method can be used to remove undesirable compounds from tobacco, tobacco materials or tobacco smoke.
