- Description
- Mature green tomatoes (Solanum lycopersicum cv Neang Pich) were exposed to 0, 3.1, 7.1, 10.5 and 13.6 kJm-2 UV-C irradiation at 20°C. After treatment, tomatoes were stored in continuous air containing either < 0.005 or 0.1 µL L-1 ethylene at 20°C and 100% RH for up to 11 days. The untreated fruit (0 kJm-2 UV-C) ripened significantly faster than UV-C treatments for both storage conditions. UV-C treatments followed by storage at both of < 0.005 and 0.1 µL L-1 ethylene had significantly slower ethylene production rates throughout the ripening period. There was no difference between treatments in fruit TSS, TA and, TSS/TA ratio. After storage, treated fruits with 10.5 and 13.6 kJm-2 UV-C were significantly firmer than untreated fruits for both storage conditions. Overall, tomatoes stored at < 0.005 µL L-1 ethylene were significantly firmer and higher in TSS/TA ratio than fruits stored at 0.1 µL L-1 ethylene. These results show that UV-C treatment delayed ripening of tomatoes in the presence of low level of ethylene during storage. In the absence of ethylene, UV-C treatment resulted in higher firmness value, TSS and TSS/TA ratio. This new treatment could be used to extend the shelf-life of mature green tomatoes through the supply chain without the use of refrigeration.
