In addition, when the blending ratio of the low nicotine leaf tobacco was about 5%, it was expected that no difference would be recognized, so the value of a was set to “0.05”.
  • the threshold value of the blending ratio of low nicotine leaf tobacco was calculated to be about 33.1% by weight. This means that when the low nicotine leaf tobacco is blended at about 33.1% by weight or less, most smokers do not notice a decrease in the intensity of smoking. Therefore, it can be seen that in order to maximize the reduction of the tobacco smell and minimize the decrease in the strength of the smoking taste, it is preferable that the low nicotine leaf tobacco is blended at around 30% by weight.

Abstract

L'invention concerne un article à fumer ayant une odeur réduite de cigarettes et son procédé de fabrication. Les articles à fumer selon certains modes de réalisation de la présente invention comprennent une partie de matériau à fumer contenant des matériaux de cigarette et une partie filtre, les matériaux de cigarette pouvant comprendre un matériau produit par traitement du tabac en feuilles ayant une teneur en nicotine inférieure ou égale à 0,5 %. Dans un tel cas, un composant de nicotine et un composé d'azote, qui sont les causes principales de l'odeur de cigarette dans la fumée de cigarette, sont réduits, de telle sorte que l'odeur de cigarette de la fumée générée pendant le fumage peut être considérablement réduite.
