Abstract Pepino dulce (Solanum muricatum Aiton) or Pepino has been growing to produce edible, juicy and attractive fruits. The imported fruits and national small scale of Pepino dulce production are currently stored and commercialized under the absence of postharvest handling recommendations. Therefore, this work aimed to evaluate the quality aspects of Pepino dulce fruits in distinct ripening stages, forms of packaging and conditions of storage. The trial was conducted in a 2x2x2 factorial scheme - 2 ripening stages (ripe and immature) x 2 forms of packaging (with and without wrapping in plastic film) x 2 conditions of storage (room: 25 °C ± 2 ºC and 57% ± 5% of relative humidity (RH); cold: under refrigeration 10 °C ± 2 °C and 85% ± 5% of RH) – in a complete randomized block design. Fruit quality attributes, such as vitamin C, chemical and phenolic content, fruit color (mesocarp), firmness, dry matter content, total titratable acidity (TA), total soluble solids and pH, were evaluated. Fruits showed a centesimal composition with low calories and a significant content of potassium (K), phosphorus (P) and magnesium (Mg), which can contribute to the daily supply of these elements. For commercialization purposes, the association of packaging (plastic wrapping film) and refrigerated storage (cold: 10 °C ± 2 °C and 85% ± 5% of RH) to maintain the characteristics of fruit quality after a 15 days period is more important than its individual use.
