摘要
The combined effects of 1-methylcyclopropene (1-MCP), calcium chloride and heat treatment on firmness and cell wall components of fresh-cut ripe papaya were elucidated during storage at 10 degrees C. Papaya were treated with 500 nl L-1 1-MCP before and after cutting and/or dipped in 1.0% calcium chloride at 25 or 50 degrees C. Firmness, water soluble pectin (WSP), ammonium oxalate soluble pectin (AOSP) and the activity of enzymes pectin methylesterase (PME) and polygalacturonase (PG) were examined every 2 days in storage. 1-MCP treatment in combination with calcium chloride dip either at 25 or 50 degrees C could reduce softening, decreased the WSP content and reduced PME and PG activities. It was concluded that application of 1-MCP, calcium chloride and heat treatments exhibited synergistic effects on firmness and cell wall components of fresh-cut ripe papaya.
