    Effects of pyrolysis conditions on the formation reaction of 4-aminobiphenyl in non-isothermal pyrolysis of tobacco

    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
    4-Aminobiphenyl (4-ABP) is a polycyclic aromatic amine in cigarette smoke. Previous reports indicate that proteinaceous compounds (e.g. amino acids, peptides and proteins) in tobacco can highly contribute to the yield of 4-ABP measured in smoke. In a ...
