Abstract
Batches of 50 tomatoes, grown under uniform conditions in experimental plots, were dipped in water at 41-42 degree C for 10 min, air dried and stored in wooden crates at 21-35 degree C with RH 45-65%. During 8-12 days storage, the ripening rate was observed, and at the end of storage, TS, acidity and lycopene contents were measured. Tomatoes treated at the breaker stage of maturity (with a tinge of yellow on a green surface) ripened faster after the 4th to 6th day of storage than untreated controls. The lycopene content was also significantly higher (977-1058 mug/g) than in the controls (848-889 mug/g). Tomatoes treated at the turning stage (with 50-75% yellowing) ripened in 6 days, whereas controls required 8 days. The treatment had no significant effect on TS, acidity or spoilage of the fruits.
