Definitions

  • the present invention relates to a method for the pasteurization of tobacco, in particular fine- cut tobacco, which comprises heating the tobacco such that the tobacco is pasteurized.
  • Roll-your-own and make-your-own tobacco products have a relatively high moisture content of typically above 18 weight percent. In comparison, pre-manufactured cigarettes typically have moisture content below about 14 weight percent.
  • the high moisture content in roll-your-own and make-your-own tobacco facilitates, for example, the handling by the consumer when making cigarettes.
  • tobacco is an organic product, it may be subject to deterioration by microorganisms, such as mold. In moderate climates, mold spores are naturally present everywhere and the mold growth is favored by moisture.
