This study evaluated the effect of passive modified atmosphere packaging (MAP) using BreatheWay® technology on the postharvest quality of pink tomatoes (Solanum lycopersicum L. cv. ‘BHN 589’) when stored at optimum and above-optimum temperatures. Pink tomatoes were packaged in MAP or perforated trays and stored at the optimum temperature of 12.5 °C or at 21 °C, for 35 or 21 days, respectively. MAP significantly delayed ripening and maintained quality at both temperatures. The tomatoes in MAP demonstrated decreased electrolyte leakage, firmer fruit as well as slower color development and lycopene accumulation. Fruit in MAP had more β-carotene but there was no effect on ascorbic acid. However, the control tomatoes stored at 21 °C demonstrated higher antioxidant capacity and total phenols. Overall, tomatoes in MAP maintained higher overall quality compared to the air control and demonstrated a shelf life extension of approximately 5 days at 12.5 °C and 3 days at 21 °C.
