This research was conducted to identify the optimum harvest maturity stage/s that yielded the highest nutritional quality and longest marketable shelf-life. “TY Megaton” and “Yureka” cultivars were harvested at the breaker, pink, and red stages and stored up to 20 days at 12°C with 85 ± 5% relative humidity (RH). Quality attributes, the contents of important secondary metabolites, and antioxidant activity were assessed during the storage period. Storing and marketing of tomato fruits up to 3 weeks could be possible. However, a gradually decreasing trend of ascorbic acid and total phenolic content was observed as the maturity stage and storage period proceeded, irrespective of the cultivar. Results of lycopene content and antioxidant activity suggest that better nutritional benefit from the breaker and pink stages could be obtained after 16 and 12 days of storage, respectively, and from the beginning to eighth day of storage for the red stage.
