    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...
