Pepper (Capsicum annum L.) is a highly perishable vegetable, which reduces its post-harvest life if not properly preserved. The objective was to analyze the efficiency of different plastic coatings on postharvest conservation of green peppers. The peppers were purchased at CEASA in São Luís (MA) and sent to the laboratory. The design used was completely randomized, in a split subdivided over time (3, 6, 9 and 12 days of storage), with three treatments (without packaging, plastic film and airtight bag), four replicates and two fruits per portion (tray). The peppers were stored on a bench, in ambient condition (T = ± 25 ° C; RH = 48%), for 12 days. Fresh weight loss, total titratable acidity (TTA), pH and total soluble solids were evaluated, as well as their correlations in the ripening of peppers. At the end of the study, the use of an airtight bag is recommended for postharvest conservation of green peppers, as this technology provides conservation of important quality attributes, such as fresh mass, acidity, pH and soluble solids, during 12 days of storage environment. This can reduce quantitative and/or qualitative losses, with positive effects on the socioeconomic and environmental indicators of the marketing of green peppers.
