Resumo: | Although causing extensive damage, bagging coffee cherries before drying occurs even in the field due to adverse factors soon after boltering, such as rain during the harvest, problems during transport to the drying area or even the poor plantation design, besides the lack of mechanical dryers for most small producers, thus requiring a more scientific foundation. Given this fact, the aim of this study was to evaluate the real effect of this practice on the quality of coffee in different stages of maturation, bagging from up to four days before drying, and to verify the behavior of different stages with regard to this procedure. Physical, chemical, and physicochemical analysis as well as classification according to type and drink were performed using Acaiá coffee fruits (Coffea arabica L.) collected at Perdões - MG and separated by hand after picking, in four maturation stages (green / greenish yellow, cherry, dried pruns and fruit mixture). After separation, they were packed in polyethylene bags and subjected to five bagging times ranging from 0, 1, 2, 3 and 4 days. After each period, samples were dried in a concrete yard for analysis. The analysis results showed that the electrical conductivity parameters, leaching of potassium and PPO activity were shown to be as important quality markers. Taste tests classified most treatments as “hard coffee”. Based on these results it was found that bagging promoted loss of bean quality from the first day. |

Diante desse fato, objetivou-se com este estudo avaliar o real efeito dessa prática sobre a qualidade do café em diferentes estádios de maturação, ensacados por até quatro dias antes da secagem, bem como verificar o comportamento dos diferentes estádios com relação a esse procedimento. Análises físicas, químicas, físico-químicas e classificação quanto ao tipo e bebida foram realizadas em frutos de café da cultivar Acaiá (Coffea arabica L.), coletados no município de Perdões - MG e separados manualmente após a derriça no pano, em quatro estádios de maturação (verde/verde cana, cereja, passa/seco e mistura de frutos). Depois da separação, os mesmos foram acondicionados em sacos de polietileno trançado e submetidos a cinco tempos de ensacamento, variando em 0, 1, 2, 3 e 4 dias. Após cada período, as amostras foram secas em terreiro de cimento para a realização das análises. Os resultados das análises apontaram que os parâmetros condutividade elétrica, lixiviação de potássio e atividade da polifenoloxidase mostraram-se como importantes marcadores de qualidade. A prova de xícara classificou a maioria dos tratamentos como Dura. Diante dos resultados obtidos, o ensacamento promoveu perda de qualidade dos grãos, a partir do primeiro dia.Universidade Federal de Lavras2014-11-13T13:17:16Z2014-11-13T13:17:16Z2011info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleANGÉLICO, C.
