Abstract Sapodilla (Manilkara zapota (L.) P. Royen) is a climacteric fruit, very perishable, with high metabolic activity, rapid ripening and reduced storage time at room temperature, thus making difficult its commercialization. However, this research aimed to evaluate the effect of potassium permanganate (KMnO4) on the quality and post-harvest conservation of sapodilla fruit under modified atmosphere at room temperature. The sapodilla fruits were harvested when they reached physiological maturity and then accommodated in Styrofoam trays with PVC film coating. Within each package, KMnO4 were placed at different concentrations (0, 0.250, 0.375, and 0.500 g of KMnO4 per kg of fruit, respectively), impregnated in vermiculite. In addition, were kept in storage at room temperature (25 ± 1 °C and 54 ± 5% RU) for fifteen days, with fruit quality analysis every five days. The potassium permanganate doses influenced the sapodilla fruit quality, wherein the concentration of 0.375 g of KMnO4 per kg of fruit was the most efficient, retarding the loss of firmness and vitamin C degradation of sapodilla fruits throughout five days storage under modified atmosphere at room temperature. The sapodilla fruit postharvest life stored under modified atmosphere with potassium permanganate 25 ± 1 °C and 54 ± 5% RU, is ten days.
