The effects of 1-MCP and DPA treatments on antioxidant activity of‘Dangshansuli'pear and their relationship with superficial scald development during cold storage
An experiment was conducted to study the relationship between antioxidant activity of‘Dangshansuli'pear and the superficial scald development during cold storage.The results showed that both 1.0μL/L 1-methylcyclopropene(1-MCP)and 2 000μL/L diphenylamine(DPA)treatments strengthened the activity of superoxide dismutase(SOD)and peroxidase(POD)and decreased total phenols,malondialdehyde(MDA),polyphenoloxidase(PPO)activity and cell membrane permeability with remarkable antioxidation activity in the pear peel,the...
