Postharvest Produce Guide - Tomato

Harvest at the Mature Green 2 stage at a minimum, however many buyers prefer more color so know the buyer’s preference, which is often the breaker or pink stage. Shape should be typical of variety (round, roma, etc.) and well developed; color should be uniform, no green shoulders.

The optimum temperature for tomatoes which ensures best ripening and flavor is 68°F at 90-95% RH with good air circulation. Tomatoes are sensitive to chilling injury at temperatures below 50°F held for longer than a 2 week period, or for a shorter time (6-8 days) at 41°F. Chilling injury is cumulative beginning in the field, and may result in poor color development, uneven ripening, surface pitting, seed browning, and issues with rot.
