  • the weight contents of dry matter of the plant fibres, of the plant extract and of plant dust in the reconstituted plant sheet are indicated in the table below.
  • the reconstituted plant sheet is subjected to a Buroma cutting test.
  • the loss of plant dust is 2.6%, which is very low.
  • the reconstituted tobacco sheet obtained is then shredded in order to be smoked without combustion.
  • the organoleptic properties of the aerosol thus generated are satisfactory for the user.
  • Two fibrous supports having a basis weight of 32 g/m 2 are obtained by passing plant fibres into a papermaking machine. 2.7 g of mint dust are then sprinkled onto a wet face of one of the two fibrous supports. The sprinkled fibrous support thus obtained is then dried.
  • the stacking of the second fibrous support and of the sprinkled and dried fibrous support is then carried out by adhesion of a wet face of the second fibrous support with the face of the sprinkled and dried fibrous support in contact with the plant dust in order to form a sandwich of fibrous supports, in which the dust is trapped between the two fibrous supports.
  • the sandwich of fibrous supports is then dried using a device of Rapid Kothen type.
  • the dried sandwich of fibrous supports is then impregnated with 3.64 g of tobacco extracts and glycerol in order to obtain a sandwich of impregnated fibrous supports.
  • the sandwich of the impregnated fibrous supports is then dried at 90°C for 540 seconds.
  • the weight contents of dry matter of the plant fibres, of the plant extract and of plant dust in the reconstituted plant sheet are indicated in the table below.
  • the reconstituted plant sheet is subjected to the same Buroma cutting test as the reconstituted plant sheet of Example 1.
  • the loss of dust is 4.9%>, which is very low.
  • the reconstituted plant sheet obtained is then shredded in order to be smoked without combustion.
  • the organoleptic properties of the aerosol thus generated are satisfactory for the user.
