Abstract:

In order to investigate the effect of 1-methylcyclopropene (1-MCP) on its postharvest physiology and storage
quality, Termitornyces albuminosus was fumigated with different concentrations of 1-MCP (0.5, 1.0, 1.5 μL/L) at room
temperature (25 ± 2) ℃ and then stored at low temperature (4 ± 1) ℃. The results indicated that 1-MCP treatment could
significantly improve storage quality of Termitornyces albuminosus as indicated by significantly reduced respiration intensity
and increased soluble sugar content and catalase activity compared with the untreated control. Treatment with 1-MCP
not only retarded the degradation of soluble protein but also inhibited the accumulation of malondialdehyde content and
polyphenol oxidase activity. In conclusion, 1-MCP treatment could inhibit physiological metabolism, maintain quality,
and delay the senescence of Termitornyces albuminosus. The optimal concentration of 1-MCP was 1.0 μL/L for storage of
Termitornyces albuminosus. Under this condition, no obvious browning and cap opening were found. The freshness degree
could reach 0.51 after storaged at (4 ± 1) ℃ for 12 days. Thus, 1-MCP treatment was able to effectively prolonge the shelf
life of Termitornyces albuminosus and consequently was effective in preserving its commercial value.

Key words: Termitornyces albuminosus, 1-methylcyclopropene (1-MCP), postharvest physiology, storage quality
