The work aims to summarize the storage and preservation packaging technologies for spinach at home and abroad and analyze the effects of the technologies on postharvest physiology and biochemistry, nutrient, nitrate and nitrite content of spinach, to provide theoretical reference for spinach storage and preservation and control of harmful substances. The methods used for the storage and preservation of spinach were analyzed, including low temperature, air conditioning, 1-MCP, irradiation, chlorine dioxide and ozone, and the influence and regulation of different storage methods on nitrates and nitrites in spinach were summarized for the problem of nitrate and nitrite accumulation during storage. There are still some defects in various traditional storage and preservation techniques, especially for the quality safety problems. Moreover, the relationship between the storage method and spinach decay and the formation of harmful substances should be made clear in combination with basic research, so as to provide new research direction and ideas for the study of spinach storage preservation and quality safety.
