Definitions

  • the present invention relates to a smokeless tobacco composition, and to a process for producing the smokeless tobacco composition.
  • Tobacco fermentation is generally a process that starts spontaneously soon after the tobacco is harvested. As tobacco fermentation was early on found to enhance certain properties of the tobacco, such as smell and taste, this spontaneous process is frequently consciously stimulated in various industrial processes in the course of tobacco production.
  • a smokeless tobacco composition comprising bleached tobacco material, wherein at least 50% by weight of the bleached tobacco material has a particle size of from about 1 mm to about 50 mm.

  • 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.
