Abstract

The use of phytosanitary regulations to prevent the spread of pests into new areas is frequently required for international trade.
Currently, Thai fresh pomelos are permitted to be exported to the United States and require to be treated with ionizing radiations as a phytosanitary treatment before being exported using gamma ray or X-ray at a generic dose.
In this study, the effect of gamma irradiation on the postharvest quality of pomelo cultivar ‘Thong Dee’ (Citrus maxima (Burm.) Merr.), was evaluated and was carried out on a commercial-scale experiment to observe how shelf-life of pomelo during shipment and storage.
Pomelos were irradiated at 400 Gy using gamma ray (1.25 MeV) from the Co₆₀ source and stored at 13-15°C for 50 days, pomelo were not treated with radiation as a control group.
After irradiation, gamma radiation did not affect pomelo peel or external damage when compared to control.
Neither irradiation affected characteristics, weight loss, fruit firmness, peel color, TSS/TA ratio, respiration rate, and ethylene production.
In addition, decayed fruits were found after irradiation on day 30 of control and irradiated fruit with 12.98 and 5.17%, respectively.
The quality of irradiated pomelo was similar to non-irradiated pomelo stored at refrigerated temperature for 50 days.
The results suggest that irradiation could serve as a potential quarantine treatment for ‘Thong Dee’ Thai pomelo with good qualities and appearance which appropriate handling process and storage temperature.
