In the gas chromatogram of the particulate phase from flue-cured tobacco smoke, several pairs of peaks were selected and the logarithms of the ratios in the area of the individual pairs were calculated to see their correlation to the corresponding organoleptic evaluations. The correlation coefficients obtained were generally higher than those obtained previously merely from the ratios of peak areas. Using the logarithmic values as variables, the linear equations for the evaluation of the individual organoleptic characteristics were computed. The results were applied to twenty kinds of flue-cured type tobaccos, including tip, leaf and cutter for each, and the calculated values were compared with the corresponding organoleptic evaluations. The individual estimated values obtained from the present method were significantly correlated to the values of the corresponding organoleptic evaluations.
