Quality of long storage tomato fruits is characterized by their extended shelf life, which depends on some endogenous enzymatic activities that may work as qualitative markers of tomato fruit spoilage. Among these activities, the role of pectinesterase and polyphenol oxidase was evaluated in some tomato types cultivated in Sicily in comparison with the multi-locular type Riccio catanese and the F1 hybrid Naomi of cherry tomato. The types Pizzutello di Trapani and Riccio catanese showed lower polyphenol oxidase activity and the latter was also characterized by the highest lycopene content. The lowest pectinesterase activity was observed in Percopara di Lipari

Abstract
Quality of long storage tomato fruits is characterized by their extended shelf life, which depends on some endogenous enzymatic activities that may work as qualitative markers of tomato fruit spoilage. Among these activities, the role of pectinesterase and polyphenol oxidase was evaluated in some tomato types cultivated in Sicily in comparison with the multi-locular type Riccio catanese and the F1 hybrid Naomi of cherry tomato. The types Pizzutello di Trapani and Riccio catanese showed lower polyphenol oxidase activity and the latter was also characterized by the highest lycopene content. The lowest pectinesterase activity was observed in Percopara di Lipari| File | Dimensione | Formato | |
