RESUMO:

The coffee culture is extremely important for Espírito Santo, besides playing a large role in the Brazilian economy. Increasingly the consumer market has been demanding regarding coffee quality, and taken into account environmental, social and food safety issues in the process of choosing what to consume. A to also consider the existing minimum quality rules for the marketing of the product for the domestic market and exporting countries. Regarding sanitary aspects, a major concern is with mycotoxins from fungal contamination, which deteriorate the quality and may even pose risks to consumer health. In addition to the need to meet the minimum requirements laid down in the regulations, producers have been faced with the demand for specialty coffees, an expanding market in the world. Thus, this work aimed to evaluate the adoption of good agricultural practices recommended by agroecology and organic agriculture as a factor of improvement in the classification of arabic coffee as the quality of the beverage and in the reduction of fungus contamination in the fruits harvested. The study was carried out in rural property of the micro region of Caparaó capixaba, in the municipality of São José do Calçado / ES. The treatments consisted in the association of different harvesting and postharvest forms commonly adopted in the property and throughout the region. The types of harvest considered were: selective, on the cloth and sweeping; the fruit picking point: mixed or just cherry and the type of terreiro used for drying: concrete, concrete under plastic greenhouse and clay. Physical and sensorial analyzes and fungal taxonomy were performed. Statistical analysis was performed using Sisvar software, version 5.6. Traditional harvesting systems, by means of ground or cloth collapses, have generally produced low-quality, low-defect coffees. Grains that showed direct contact with the soil during the harvest and / or drying process showed higher fungal infestation severity indexes when compared to grains not exposed to soil. Harvest and post-harvest processes that separate lots of cherry coffee for individual drying showed lower levels of infestation severity. Different genus of fungi were detected in the grains, being: Aspergillus, Penicilium, Fusarium, Cladosporium, Uredimiosporo, Colletrotrichum and Alternaria. The selective harvest of Arabica coffee (Coffea arabica) has demonstrated the potential to improve the beverage quality of the species in Caparaó Capixaba, as it drastically reduces grain contamination. Thus, it is believed that other harvesting and post-harvesting techniques (pulping, peeling and drying in suspended screen terrariums) should be studied in association with selective harvesting in order to verify its efficiency and profitability of application in Caparaó Capixaba aiming to production of specialty coffees.
