Evaluation of 1-methylcyclopropene (1-MCP) treatment combined with nano-packaging on quality of pleurotus eryngii

The aim of the present study was to investigate the effect of 1-methylcyclopropene (1-MCP) combined with nano-packaging on quality of pleurotus eryngii stored at 4 +/- 1 degrees C for 12 days. Texture, respiration rate, soluble protein, soluble sugar, weight loss, soluble solid, malondialdehyde (MDA) content, polyphenol oxidase (PPO), superoxide dismutase (SOD) and catalase (CAT) activity of treated pleurotus eryngii were determined. The results suggested that 1-MCP treatment combined with nano-packaging reduce respiration rate, weight loss and MDA content, delayed the decrease of soluble protein content, and maintained soluble sugar and soluble solid content of treated pleurotus eryngii during the storage at 4 +/- 1 degrees C compared with the untreated samples. The efficiency of the combined treatment (1-MCP + nano-packaging) was better than that of 1-MCP or nano-packaging alone. Moreover, 1-MCP plus nano-packaging treatment effectively improved SOD and CAT activities, and suppressed the increase of PPO activity in pleurotus eryngii. Therefore, present results indicated that 1-MCP plus nano-packaging treatment may be an effective technology on maintaining commercial quality and lengthening shelf life of pleurotus eryngii.
