Gansu Agricultural University, Lanzhou Gansu 730070, China 2. Agricultural Product Storage and Processing Institute, Gansu Academy of Agricultural Sciences, Lanzhou Gansu 730070, China) Abstract:In order to solve the problem of yellowing and mildew of broccoli during the storage, broccoli was treated with 1-methylcyclopropene(1-MCP), lysozyme and 1-MCP + lysozyme, and then stored at low temperature(2 ℃), sensory quality and physiological changes were observed. The results showed that all treatments can improve the sensory quality and total phenol content of broccoli, inhibit the degradation of chlorophyll and Vc, and enhance the activity of SOD and CAT, and the combined treatment of 1-MCP+lysozyme had the best effect on the freshness preservation of broccoli.
