The relationship between gas chromatographic (GC) data and subjective sensory evaluation was analyzed in 31 arabica coffee by multivariate analysis. Using Quantification Theory 3 for sensory data, the samples were classified into six groups. The relationships between GC data and scores on axis 1 and 2 obtained by Quantification Theory 3 were analyzed by multiple regression analysis. The multiple correlation coefficient (R) was O.85 at step 7 and 16. On the basis of the R and F-value, the multiple regression models were determined for estimating the scores on axis 1 and 2. The result suggested that the aroma profiles of the coffee samples were closed to the sensory evaluation.
