  • the term “about” also encompasses amounts that differ due to different equilibrium conditions for a composition resulting from a particular initial mixture. Whether or not modified by the term “about”, the claims include equivalents to the quantities.
  • the term “bleached” refers to an object, such as for instance a tobacco raw material, whose visible color has been reduced by any known method for this purpose, such as washing with one or more solvents, or treatment with one or more bleaching agents, or any combination thereof.
  • “fermentable carbohydrates” refers to carbohydrates that can be metabolically broken down in and by the human body, specifically starch, glucose, fructose and sucrose.
  • oral in connection to a product refers to the product, in normal use, is suited to be placed somewhere in the oral cavity of the user, for example under the lips, in the same way as moist snuff products are generally used.
