Abstract

La présente invention a trait à une feuille destinée à une cigarette, à son procédé de préparation et à une cigarette. La feuille destinée à une cigarette est constituée d'une feuille de thé ou d'une tige de thé. Son procédé de préparation inclut les étapes suivantes consistant : à tremper la feuille de thé ou la tige de thé dans de l'eau à une température de 60 à 80 °C ou à température ambiante de manière à obtenir une feuille de thé ou une tige de thé enflée ; à tordre la feuille de thé ou la tige de thé enflée de manière à obtenir une fibre grossière de la feuille de thé ou de la tige de thé ; à laver la fibre grossière de la feuille de thé ou de la tige de thé dans de l'eau à une température de 60 à 80 °C ou à température ambiante de manière à obtenir une fibre de la feuille de thé ou de la tige de thé ; à broyer la fibre de la feuille de thé ou de la tige de thé de manière à obtenir une pulpe de la feuille de thé ou de la tige de thé ; à mélanger la pulpe de la feuille de thé ou de la tige de thé et une pulpe d'une fibre renforcée de manière à obtenir une pulpe finale ; à fabriquer une base de feuille avec la pulpe finale ; et à sécher une première fois, à enrober et à sécher une seconde fois la base de feuille de manière à obtenir la feuille destinée à une cigarette. Le procédé inclut aussi l'étape consistant à ajouter un agent de réduction des risques lors de la mise en pâte et/ou de l'enrobage de la base de feuille. La feuille destinée à une cigarette permet de résoudre les problèmes de l'art antérieur de limitation de l'effet de réduction des risques et de non stabilité de l'additif, ce qui permet d'obtenir une réduction des risques.
