A method for producing a vaporisable material comprising plant fibres for use in a vapour generating device which generates a vapour by heating the vaporisable material is disclosed. The method comprises reducing the particle size of the plant fibres to less than 1.5 mm and mixing plant fibres of at least two ranges of particle size. The invention also relates to vaporisable material for use in a vapour generating device obtainable by the method.

Provided is a tobacco raw material having a low content of specified polycyclic aromatic hydrocarbons and low-molecular carboxylic acids and containing a large amount of specified flavor components, and a method for manufacturing the tobacco raw material. The objective is achieved with a manufacturing method including: a step for drying pre-deribbing leaf tobacco after harvesting until the moisture content thereof reaches 10-25 wt %; a step for smoke-processing the pre-deribbing dried tobacco using thermally decomposed smoke at 400-500 C.; and a step for, after the smoke-processing step, storing the pre-deribbing smoke-processed leaf tobacco under partially sealed conditions.

The present invention relates to an improved method for preparing a tobacco composition suitable for use as a smokeless tobacco composition wherein the tobacco material can be cooled down, after being heated to a temperature of 80 C. or more, to a temperature of below 25 C. during a time period of 20 min or less.

A method is provided for measuring an additive content in a tobacco paper for electric cigarettes produced from a pulpy mass of additives, water, flavoring substances and tobacco that is dried to form a tobacco paper having a single-layer. The method includes measuring the tobacco paper using at least one microwave resonator having two resonance modes with two resonant frequencies (f.sub.L, f.sub.H). A lower of the two resonant frequencies (f.sub.L) is in a range that is less than 1 GHz and a higher of the two resonant frequencies is in a range that is more than 2 GHZ. A density-independent moisture value (?.sub.L,H) is determined for each of the two resonance modes and a glycerol content (g) is determined depending on two moisture angles.
