  • Method of treating tobacco extract solution to reduce magnesium ions and method of manufacturing a treated tobacco material
    Patent number: 8011373
    Abstract: A method of treating a tobacco extract solution includes bringing an extract solution, which is obtained by extracting a natural tobacco material with an aqueous extracting solvent, into contact with a polymer containing, in its side chain, a functional group which traps metal ions including at least magnesium, thereby obtaining an extract solution with an amount of at least magnesium reduced.
