Título:  The consistency in the sensory analysis of coffees using Q-graders.

Conteúdo:  The process of sensory evaluation is widely used in the coffee classification worldwide. This evaluation is popularly known as ?Cupping Test? and constitutes the principal methodology to assess the final quality of the coffee drink. This study observed the effect of the interaction among Q-graders, as well as the coffee tasting process in the morning and in the afternoon. The study was conducted with trained tasters with Q-Grader certificates. The methodology followed the analysis protocol guidelines of the Specialty Coffee Association of America, SCAA, with the participation of two testing groups, each one with two Q-graders for the analysis. T Tests, followed by the Pearson?s correlation and the analysis of hierarchical grouping were used for the data analysis. The results indicate that the tasters have full capacity of evaluation, although there are variances in relation to the perceptions of the attributes that define the best coffees. The results also indicate that the effect of the shift, when isolated from interaction, interfere neither in the evaluation of the batches, nor the performance of the tasters; however, when associated with interaction (chatting), the analysis indicate distortions, highlighting the need of improving the techniques of sensory evaluation.

Título:  Relationship between sensory and microbial profiles of fermented coffee by dry and washed methods.
Ano de publicação:  2023
Fonte/Imprenta:  Food Chemistry Advances, v. 2, p. 1-10, 2023.

Conteúdo:  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.
