Resumo
10.1016/j.radphyschem.2004.04.026Ionizing radiation can be used to control spoilage microorganisms and to increase the shelf life of fresh fruits and
vegetables in replacement for the treatment with chemical fumigants. In order to enforce labelling regulations,methods
for detecting the irradiation treatment directly in the produce are required. Recently,a number of detection methods for
irradiated food have been adopted by the Codex Comission. A rapid screening method for qualitative detection of
irradiation is the DNA Comet Assay. The applicability of the DNA Comet Assay for distinguishing irradiated papaya,
melon,and watermelon was evaluated. The samples were treated in a 60Co facility at dose levels of 0.0,0.5,0.75,and
1.0 kGy. The irradiated samples showed typical DNA fragmentation whereas cells from non-irradiated ones appeared
intact. In addition to the DNA Comet Assay also the half-embryo test was applied in melon and watermelon to detect
the irradiation treatment.
