Ozone can improve cucumber postharvest through higher firmness and reducing the decline rate of chlorophyll

The objective of the work was to investigate the effects of ozone treatment on the storage quality of postharvest cucumber. The cucumbers packed in micro-porous film were treated with 1, 3 and 5 ?g/mL ozone for 15 min every other day at 7?C. The hardness, total soluble solids (TSS), titratable acid (TA), vitamin C, chlorophyll, malonaldehyde (MDA) and peroxidase (POD) activity were detected to determine the proper concentration of ozone.? Compared with the control group, 5 ?g/mL ozone could sustain high hardness, reduce the decline rate of chlorophyll, vitamin C, TA and TSS content, prevent the accumulation of MDA, and inhibit the activity of POD effectively. Conclusion is that ozone treatment can maintain physiological and biochemical indexes and improve the storage quality of cucumber effectively, and 5 ?g/mL ozone has the best effect.
