Purpose: This study investigated the sensory characteristics of Colombian coffee, by comparing the different decaffeination processes and roasting conditions.
Methods: Colombia green bean samples were subjected to three different processes, washed(regular), Swiss Water Process(decaffeinated), Supercritical CO2(decaffeinated), and three roasting conditions. The sensory characteristics were subsequently measured by applying the QDA. PCA and PLSR were further analyzed according to results obtained in the QDA.
Results: Totally, 19 descriptors were derived from the QDA results. In most cases, there were no significant differences when considering the characteristics obtained with the same roasting condition for regular coffee and decaffeinated coffee. Two components were identified from PCA. Positive(+) PC1 was obtained for sourness, fruits flavor, floral aroma, fermentation aroma, etc., and also included CSL and CCL. Negative(-) PC1 included astringency, bitterness, chocolate flavor, earthy flavor, etc., as well as CSD and CCD. The correlation between sensory characteristics and customer acceptance was examined by applying PLSR. The result showed that CSD, CCD which dark roasted samples demonstrated the most proximate results for the preference characteristics.
Conclusion: Results of this study implicate two significant factors: the comparison of regular coffee and decaffeinated coffee, and development of descriptors in decaffeinated coffee through QDA. This study also indicates that decaffeinated coffee is an alternative for consumers who like coffee but want to reduce caffeine consumption.
