Postharvest effect of gaseous ozone on physicochemical quality, carotenoid content and shelf-life of mango fruit

This study investigated the effect of gaseous ozone (O 3 ) exposure time on the postharvest quality and shelf-life of mangoes. "Keitt" mango fruit harvested at physiological maturity was exposed to 0.25 mg/L of O 3 for 12, 24,36, or 48 hours, and the control fruit were untreated. Fruit were thereafter stored at 10 ℃ for three weeks and ripened at ambient temperature for one week. Postharvest parameters such as mass loss, decay incidence, firmness, total soluble solids (TSS), titratable acidity (TA), and carotenoid content were assessed at weekly intervals. The findings showed that the physiological weight loss of untreated fruit (30.92%) was significantly higher (p
