When it comes to the sensory analysis of specialty coffees, it is necessary to discuss the protocol of tests of the Specialty Coffee Association (SCA) and the formation of Q-Graders as reliable parameters in the sensory analysis. However, the training of these Q-Graders and the use of the SCA protocol has generated discussions in the scientific community and demonstrated the importance of talking about the level of professional precision as well as the use of the protocol. This study sought to understand the relation of accuracy and efficiency of the Q-graders and protocol in the sensory analysis of coffees. Three experiments were carried out to evaluate and test the hypotheses regarding the level of precision in relation to the shift, the number of samples and the judgment abilities of Q-Graders due to the quality of the specialty coffee and non-specialty coffee. These three experiments were performed by seven Q-Graders in an isolated environment during three consecutive days with 137 specialty coffee samples and 7 non-specialty coffee samples as defined by the SCA. The results indicate that the Q-Graders present high precision when evaluating excellent and outstanding coffees, as defined by the SCA. In addition, the effect of the shift did not exert fatigue on the Q-Graders. However, evaluation errors were made by the Q-Graders on very good coffee (77.00 - 80.00 points), which are considered as non-specialty by the SCA, thus allowing a more in-depth discussion on what would be the boundary between a specialty and non-specialty coffee.

Objetivou-se com este estudo, avaliar a qualidade fisiológica das sementes de aroeira (Schinus terebinthifolius Raddi.) em função do estádio de maturação dos frutos e a sua possível interação com diferentes temperaturas de germinação. No experimento adotou-se o delineamento inteiramente casualizado, em que os tratamentos consistiram de um fatorial com quatro temperaturas: 25, 30, 35 0C constantes e 20-30 0C alternadas e, três estádios de maturação dos frutos: verde, intermediária e maduras. Foram utilizadas 4 repetições de 50 sementes por tratamento e a germinação foi avaliada durante 15 dias. A semeadura foi efetuada sobre papel mata-borrão, em caixas gerbox mantidas em câmara de germinação, reguladas em diferentes temperaturas, com fotoperíodo de 8 horas. Avaliaram-se a porcentagem de germinação, o Índice de velocidade de germinação (IVG), e a porcentagem de plântulas normais e anormais. As sementes extraídas de frutos maduros apresentaram qualidade fisiológica superior aos demais estádios avaliados, evidenciada principalmente nas temperaturas constante de 30 ºC e alternada de 20-30 °C, o que sugere ser esse o estádio de maturação ideal para coleta dos frutos e extração de suas sementes.
The objective of this study was to evaluate the physiological quality of seeds "aroeira" (Schinus terebinthifolius Raddi.) According to the stage of ripeness of the fruit and its possible interaction with different germination temperatures. In the experiment, a completely randomized design was used, in which the treatments consisted of a factorial with four temperatures: 25, 30, 35 ºC constant and 20-30 ºC alternating, and three maturation stages of the fruits: green, intermediate and mature. Four replicates of 50 seeds per treatment were used and the germination was evaluated during 15 days. Seeding was done on blotting paper, in gerbox boxes kept in a germination chamber, regulated at different temperatures, with photoperiod of 8 hours. 4 replicates of 50 seeds per treatment and germination assessed for 15 days were used. It assessed the percentage of germination, germination speed index (GSI) and the percentage of normal and abnormal seedlings. The seeds extracted from mature fruits presented physiological quality superior to the other evaluated stages, evidenced mainly in the temperatures constant of 30 ºC and alternated of 20-30 °C, which suggests that this is the ideal stage of maturation for fruit collection and extraction of its seeds.
