Technical Abstract: This study compared some commercially available novel, non-netted, orange-fleshed honey dew melon cultivars (Cucumis melo L. Inodorus group) and a breeding line fruit for levels of antioxidants associated with both storage quality and human health. Fruit were produced in both autumn and spring production cycles in a glasshouse, harvested at abscission (mature) and stored for up to 24 days at either 5 degrees C or 10 degrees C. Spring versus autumn production generally yielded higher overall levels of folic acid, lipophilic and antioxidant (ascrobate peroxidase, catalase, and superoxide dismutase) capacities. Our results indicate that there are significant differences in human-health and storage quality-related phytochemical profiles between orange-fleshed honey dew melon cultivars, and that high antioxidant levels are associated with reduced lipid peroxidation during melon fruit storage.
