1-MCP对鸡枞菌采后生理及贮藏品质的影响
Effect of 1-MCP on Postharvest Physiology and Storage Quality of Termitornyces albuminosus
摘要
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 1.0μL/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.关键词
