    Evaluation of combustion of a shredded tobacco bed using a reactor to produce reverse smolder:Influence of properties related to mass transfer on combustion of the bed

    NAGAO A.; YAMADA Y.; MIURA K.
    Japan Tobacco Inc., Tobacco Science Research Center, Yokohama, Kanagawa, Japan.
    The combustion mechanism of a shredded tobacco bed during puffing has been investigated. To evaluate changes in the burning rate of the shredded tobacco bed in the region close to the paper char-line, an experimental study was carried out on the reverse ...

    The quality estimation of different tobacco types examined by headspace vapor analysis

    HASEBE H.; SUHARA S.
    Japan Tobacco Inc., Tobacco Science Research Lab., Yokohama, Kanagawa, Japan.
    In order to judge the quality of tobacco leaf, it is necessary to conduct sensory smoke evaluations. However, these are subjective and the results are difficult to quantify. Therefore, we have attempted to establish a quantitative method for evaluating ...

    Internal standard-based analytical method for tobacco smoke vapor phase components

    OMORI F.; HIGASHI N.; CHIDA M.
    Japan Tobacco Inc., Tobacco Science Research Lab., Yokohama, Kanagawa, Japan.
    We developed an internal standard-based method to analyze the vapor phase components of mainstream smoke. This method collects vapor phase components from sample cigarettes, which are smoked by a linear automatic smoking machine in a sampling bag. An ...

    Development of a theoretical model to predict the efficiency of flavor adsorption for tobacco cut-filler

    NAKANISHI Y.
    Japan Tobacco Inc., Tobacco Science Research Center, Yokohama, Kanagawa, Japan.
    Historically, processes for the application of volatile flavors to tobacco cut-filler materials has depended solely on an adsorption process. Results from the author's study, employing both theoretical and empirical approaches, have indicated that ...
