    Evaluation of aroma in Oriental tobaccos as based on valeric acid gas chromatography

    DAGNON S.; TASHEVA R.; STOILOVA A.
    Inst. for Tobacco and Tobacco Products, Plovdiv, Bulgaria
    Levels of valeric acids (isovaleric and 3-methylvaleric) in leaves and smoke of different tobacco types were quantified by capillary gas chromatography (GC) using flame ionization detector (FID). The aroma characteristics of the smoke were scored by ...
