Abstract:

The effects of 1-MCP and DPA treatments on polyphenols, antioxidant activity of epicuticular wax of apple were studied. Total phenolic compounds and flavonoids in all the samples increased first and then decreased during the cold storage. 1μL·L-1 1-MCP and 2g·L-1 DPA treatments increased total phenolic compounds, flavoniods content, and DPPH·and ABTS+ radical scavenging activity in wax. Antioxidant activity was remarked positive correlated with polyphenols.

Key words: 1-MCP, DPA, wax, polyphenols, antioxidant activity
