    Comparison of the acetaldehyde, formaldehyde, and acrolein yields in cigars under different smoking regimens using a linear cigarette smoking machine

    YOUNG M.; CECIL T.L.; JOHNSON T.; FENG S.
    US Food and Drug Administration (FDA), Calverton, MD, USA
    Currently, there is very little information on the mainstream smoke yields of carbonyl compounds (e.g., formaldehyde, acetaldehyde, and acrolein) in cigar tobacco products. This study used a standard linear smoking machine and puffing protocols to...

    Development of a multi-stage liquid extraction method for the quantitative analysis of flavors in tobacco filler

    MATHIS J.A.; STANELLE R.A.; DIMANDIA J.-M.D.
    U.S. Food and Drug Administration, Atlanta, GA, USA
    A method to quantify flavor chemicals in the filler of combustible tobacco products was validated using GC-MS. The tobacco filler samples from cigarettes, little cigars, cigarillos, and cigars were prepared in a multi-step extraction procedure using...
