Item Physical and sensorial quality of arabica coffee cultivars submitted to two types of post-harvesting processing(Universidade Federal de Lavras, 2023-04-17) Alixandre, Ricardo Dias; Alixandre, Fabiano Tristão; Lima, Paula Aparecida Muniz de; Fornazier, Maurício José; Krohling, Cesar Abel; Amaral, José Francisco Teixeira do; Guarçoni, Rogério Carvalho; Dias, Rodrigo da Silva; Venturini, Cassio de Faria; Macette, Higor Alixandre; Zandonadi, Cecília Uliana; Viçosi, David BrunelliThe growing demand for better quality coffees has driven changes in the coffee production chain, mainly through the adoption of new technologies and management. Thus, this work was carried out aiming to evaluate the physical and sensorial quality of Arabica coffee cultivars, submitted to natural and pulped post-harvesting processing. The experiment was carried out following a randomized block design with three replications, in a split-plot scheme, with the plots consisting of five cultivars (Catucaí 2 SL, Catucaí 24/137, Catuaí IAC 44, Arara and Acauã); and the subplots by two processes, pulped and natural cherry. The harvest was carried out manually, harvesting the cherry fruits (ripe) in a sieve. The coffees were processed by the natural and pulped cherry methods. Drying was carried out on a covered suspended terrace, until the grains reached 11% ± 1 moisture (wet basis, bu). The following evaluations were carried out: sensorial analysis of the beverage according to the SCAA methodology, analysis of grain sieves according to the Official Brazilian Coffee Classification Protocol. The results show that all evaluated cultivars have a great potential for the production of specialty coffees in that studied environment. Differences were observed between cultivars both in the sensory quality of the beverage and in the grain size. Cultivar Arara presents a general average of final beverage grade higher than the other cultivars.Item Productivity and physical quality of grains from Coffea arabica L. in a tropical high-altitude climate in Brazil(Universidade Federal de Lavras, 2023-11-19) Martins, Adriana Novais; Turco, Patricia Helena Nogueira; Araújo, Humberto Sampaio de; Firetti, RicardoThe coffee plant is extremely important for Brazilian agribusiness as it generates foreign exchange earnings and employment throughout the production chain. In this study, we evaluated the production and parameters related to the quality of 18 Coffea arabica L. cultivars grafted onto the Apoatã IAC 2258 cultivar, in seven consecutive harvests. The experiment was installed in 2014 and carried out for seven harvests, in Fazenda Recreio in the municipality of Vera Cruz, state of São Paulo, Brazil. We used a randomised block design (DBC), with three experimental replications, which were conducted in 54 plots. We analysed productivity, yield, and grain size parameters. The data were evaluated by the analysis of variance (ANOVA) and the mean values were used to conduct the Scott-Knott and Tukey test. The results showed that in all the cycles, the characteristics evaluated showed significant differences among the cultivars. The ratio between the residual mean squares of the analysis of variance was less than 7:1 for all the characteristics evaluated, which allowed us to compare the seven harvests with each other. The cultivars IPR 100, Obatã IAC 1669–20, IPR 107 and IAC 125 RN performed the best, as determined by the parameters evaluated, and thus, we recommend these cultivars for growing coffee tropical high-altitude climate in Brazil.
