    A mixture experimental design with six variables and the effects on smoke components:1 - Presentation of this experimental design and of some initial results on physical characteristics of cigarettes and blends

    VIDAL B.; FIGUERES G.; BIESSE J.P.; BREGEON B.; LOUVET F.; MUZELLEC L.
    Altadis Research Centre, Fleury-les-Aubrais, France
    The objective of this paper is to examine the effects of six tobacco components on the chemical and physical characteristics of blends and cigarettes and particularly on the mainstream smoke yields. First of all, we will develop the philosophy of...

    A mixture experimental design with 6 variables and the effects on smoke components:2 - Hoffmann analytes behaviour through a mixture experimental design

    FIGUERES G.; VIDAL B.; BIESSE J.P.; BREGEON B.; LOUVET F.; MUZELLEC L.
    Altadis Research Centre, Fleury-les-Aubrais, France
    Today in the tobacco industry, one of the main scientific challenges is to understand the formation of some smoke compounds ("Hoffmann analytes"). For several years, work has been conducted in order to know the influence of cigarette design...

    Hoffmann analytes: Influence of cigarette paper and filter ventilation

    Papeteries de Mauduit, Quimperlé, France; Altadis, Les Aubrais, France
    Having a tool that can predict the Hoffmann analytes has become necessary, not only because of regulations, but also as a reference for the chemical composition of smoke for the Potential Reduced Exposure Products (PREPs). The work presented in...

    Prediction of a biological variable (Ames test on TPM) and of a chemical variable (TSNAs in smoke) according to the tobacco's chemical and physical characteristics

    BOUZIGE M.; VIDAL B.; BIESSE J.P.; JOUSSERAND C.; MARCHAND V.; DUMERY B.
    Altadis Research Centre, Fleury-les-Aubrais, France
    Chemical analyses of special analytes (e.g. TSNAs) or biological tests on the smoke are rather sophisticated and time consuming technologies. Giving estimates based on fast analyses would enable the blenders to have a tool allowing them to reduce...

    Near-infrared spectroscopy and pattern recognition as screening methods for classification of commercial tobacco blends

    FIGUERES G.; ANDRIEU E.; BIESSE J.P.; VIDAL B.; DUMERY B.
    Altadis Research Centre, Fleury-les-Aubrais, France
    Group classification of tobacco blends is commonly performed using several different types of compositional data including tobacco compounds, additive or process components. But all of these wet chemistry methods are relatively time-consuming. A need...

    Influence of cigarette paper, porosity and amount of citrate, and of filter ventilation on the Hoffmann analytes

    LOUREAU J.M.; BIESSE J.P.; CLARISSE G.; VIDAL B.; DEBERLY S.; LE MOIGNE C.; LE BOURVELLEC G.
    Papeteries de Mauduit, Quimperlé, France
    The measurement of Hoffmann analytes, since it has been requested in Canada and then in some of the US states and in Brazil, has become necessary. If a number of studies have already been published on the influence of some cigarette design tools...
