Effects of Ozone Combined with High Oxygen Treatment on Fresh-keeping in Postharvest Strawberry Fruits
According to literatures, both ozone treatment and high oxygen treatment can play an important role on quality-keeping and anti-fungal disease in postharvest strawberries. To date, however, no data are available concerning the effects of ozone combined with high oxygen treatment on fresh-keeping in strawberries. This paper makes an attempt to investigate the differences of freshkeeping effect on strawberries of single ozone treatment (concentration of 0.574 mg/mL and time of 30 s), single high oxygen treatment (100 ％ oxygen) and the combined treatment of the two formers. Taken contents of Vc, total phenolics, anthocyanins, values of L* & C*, and decay index as comparative parameters, there were significant differences (P<0.05) between combined treatment and single ozone or high oxygen treatment. According to the data showed in this work, it could be concluded that combined treatment had better effects on quality-keeping and anti-fungal disease in strawberries than single treatment, and the former should be a potential valuable method on fresh-keeping in postharvest strawberry fruits.
