Microorganisms influence the sensory quality of the coffee beverage through the compounds degradation or release of metabolites that diffuse into the fruit. However, type and duration of fermentation can contribute to the growth and diversity of microorganisms. Thus, the objective of this study was to analyze the microbial and sensory profile of Arabica coffees under different fruit-processing conditions and fermentation by Saccharomyces cerevisiae. Coffee cherries were used in the dry fermentation and washed fermentation at 28°C. Fermentation time ranged from 36 to 288 hours. A panel of sensory attributes was evaluated by 9 Q-graders. Mid-infrared spectra were obtained in the wavenumber range from 4000 to 650 cm?1. Microbial analyses were performed by denaturing gradient gel electrophoresis. Total sensory score for fermented coffee was higher than for unfermented coffee. In 108 and 216 hours of fermentation, the total score was higher in washed fermentation than in dry fermentation, which also shows the influence of post-harvest processing and the removal of husk on the quality of fermented coffee. Balance and body were the sensory attributes that most contributed to group formation in dry fermentation. Thus, induced fermentation increases the sensory classification of coffee beverages with positive effects on chemical and sensory profiles. |

Coffee is one of the most widely consumed beverages in the world. The genetic variability of Coffea canephora has demonstrated significant differences in the chemical compositions of genotypes, resulting in different sensory profiles in the beverage. Fermentation can also affect the sensory quality of coffee beverage. Therefore, the objective of this study was to analyze the sensory profile and the chemical groups that contribute to the sensory qualities of the coffee beverage of C. canephora var. Conilon genotypes subjected to different fermentation processes. Fermentations were carried out with 4 L of cherry coffee or peeled cherry coffee for 36 h at 25 ?. In the induced fermentation, the initial Colony Forming Unit (CFU/mL) was of 107 for Saccharomyces cerevisiae, Klebsiella sp, and Lactobacillus brevis. There was no microbial inoculation in the washed fermentation and the natural process. The sensory quality and chemical groups of the coffee were determined using the Uganda Coffee Development Authority Sensory Analysis Protocol with 6 Q-Graders and mid-infrared spectroscopy, respectively. The sensory and spectrometry analyses were able to distinguish the genotypes, highlighting the separations of genotypes A1 and Verdim with the worst sensory results, and genotype 153 with the best result. Groups formation through the mean Euclidean distance reinforces the sensory differences between fermentations. Furthermore, the greatest chemical changes in coffee beans were promoted by fermentation induced by S. cerevisiae. Thus, the genotypes and the type of fermentation influence in the sensory quality demonstrating potential for optimizing fermentations to improve the sensory quality of conilon coffee.
