This paper aims to provide theoretical reference for future research and development of new glazing tech-nology. Freezing technology is one of the preservation methods of aquatic products, and it is also the most commonly used method at present. It can maintain the quality of aquatic products effectively. Based on related researches on changes of quality of aquatic products in the process of frozen storage, and the three glazing technology technologies such as of anti-cracking, bacteriostatic and anti-oxidation glazing at home and abroad were summarized from the perspective of fresh-keeping technology of glazing. The author also provided an outlook of the future development of glazing technology. At present, the research ideas and methods of applying glazing technology to aquatic products in fresh storage are relatively mature. Some more efficient and reasonable formulas of glazing need further research. New glazing technology has broad development prospects from the perspective of development trend. Looking for formulas with good fresh-keeping performance is the future development direction.
