was studied through an Arrhenius-type relationship. The degradation kinetic constants of Weibull model increased with temperature. Therefore, initial antioxidant potential of fresh-cut watermelon was best maintained at storage temperature of 5 C for 14 days. The activation energies for lycopene, vitamin C, antioxidant capacity and total phenolic compounds were 56.5 kJ mol 1, 55.9 kJ mol 1, 34.5 kJ mol 1 and 26.9 kJ mol 1, respectively. Thus, a high temperature sensitivity of lycopene, vitamin C and antioxidant capacity related reactions were observed compared to that of total phenolic compounds.
