Nutraceutical (ascorbic acid and carotenoids) and physical (colour and firmness) parameters were evaluated in two tomato genotypes (Money maker and high pigment-1) subjected to post harvest UV-B irradiation at different ripening stages (mature green and turning). UV-B treatment increased the concentration of ascorbic acid and carotenoids in Money maker flesh and peel, while high pigment-1 fruits underwent only minor changes, suggesting that hp-1 mutation decreased the fruit ability to respond to UV-B radiation. Colour parameters appeared to be more influenced by harvesting stages than UV-B with the exception of redness (a(∗)), which in Money maker was found to increase in both flesh and peel of irradiated fruits at turning stage, although not significantly, while control was more red than treated at mature green stage. Firmness was negatively influenced by UV-B, as tomatoes were found to soften after the treatment, although this aspect needs further studies to be clarified.
