Effect of Ozone Combined with 1-MCP on the Color and Quality of Nectarines during Postharvest Storage
In order to investigate the effect of ozone regulation on the color and quality changes of nectarine treated with 1-methylcyclopropylene (1-MCP) during cold storage, nectarine test materials were fumigated with 1 μL/L 1-MCP for 24 h after postharvest, combined with ozone water atomization and ozone...

| Summary: | In order to investigate the effect of ozone regulation on the color and quality changes of nectarine treated with 1-methylcyclopropylene (1-MCP) during cold storage, nectarine test materials were fumigated with 1 μL/L 1-MCP for 24 h after postharvest, combined with ozone water atomization and ozone gas fumigation for 30 min, then packaged and stored at 0±0.5 ℃. The relevant physicochemical indexes were determined regularly. Results showed that 1-MCP combined with ozone treatment could effectively inhibit respiration rate and ethylene release, 1-MCP alone inhibited anthocyanin accumulation in pulp, hindering its red coloring, and 1-MCP combined with ozone treatment promoted red coloring in pulp at the later stage of storage. Compared with 1-MCP group alone, 1-MCP group combined with ozone treatment had higher anthocyanin content, centaurin-3-O-glucoside content, centaurin-3-O-rutin content and enzyme activity related to anthocyanin metabolism at the later stage of storage. Meanwhile, ozone gas fumigation was more conducive to anthocyanin accumulation at the later stage of storage, and the flesh red degree was higher. This study provides a new idea for improving the control of postharvest color and optimizing the application of 1-MCP in postharvest preservation. |
