    Study on the formation mechanisms of 4-aminobiphenyl in the combustion of cigarette including isotope-labelled phenylalanine

    YOSHIDA S.(1,2); KOBAYASHI K.(2)
    (1) Japan Tobacco Inc., Tobacco Science Research Center, Yokohama, Japan; (2) Graduate School of Engineering, Yokohama National University, Yokohama, Japan
    Tobacco smoke is a complex mixture of a wide variety of chemical compounds, including polycyclic aromatic amines (PAAs). In past studies, it was proposed that proteins in tobacco are major precursors of PAAs. At the 2007 CORESTA SSPT Meeting (Jeju), the ...

    The yields of aromatic amines in the pyrolysis of solvent-extracted tobacco

    YOSHIDA S.(1,2); YOSHIMURA Y.(1); KOBAYASHI K.(2)
    (1) Japan Tobacco Inc., Tobacco Science Research Center, Yokohama, Japan; (2) Graduate School of Engineering, Yokohama National University, Yokohama, Japan
    Tobacco smoke is a complex mixture of a wide variety of chemical compounds, including aromatic amines (ArAs) such as 2-aminonaphthalene (2-AN) and 4-aminobiphenyl (4-ABP). A previous study has estimated that proteins in tobacco highly contribute to the ...

    Genetic improvement of Nicotiana tabacum by applying remote hybridization and biotechnological methods

    NIKOVA V.; IANCHEVA A.M.; VLADOVA R.; PANDEVA R.; PETKOVA A.
    Bulgarian Academy of Science, Institute of Genetics, Sofia, Bulgaria.
    Wild Nicotiana species possess a high potential of useful features. Interspecific hybridization is a very effective method for the introducing of desired characters into tobacco and achieving crop improvement. Its successful realization is limited due to ...

    Color and aroma of tobacco: a facilitated approach for their objective evaluation in Oriental tobaccos and for cultivar classification within Virginia and Oriental tobacco types

    DAGNON S.; EDREVA A.; VLADOVSKA A.
    Tobacco and Tobacco Products Institutes, Plovdiv, Bulgaria; D. Kostov Inst. of Genetics, Bulgarian Academy of Sciences, Sofia, Bulgaria.
    In the routine practice the evaluation of colour and smoke aroma, major qualitative characteristics of tobacco, is mainly based on organoleptic estimates by expert panels, with this suffering from subjectivity, high costs and health hazards. We propose a ...
