The work aims to clarify the applicable methods to improve the preservation performance of fresh aquatic products, point out the existing problems and shortcomings of the preservation technology and preservation materials for fresh aquatic products, and make a prospect analysis on the development of preservation materials for fresh aquatic products in the future. The advantages and disadvantages of physical, chemical and biological technologies commonly used in fresh aquatic product preservation were introduced. The research status of plastic wrap and preservation gaskets was analyzed from classification, application range and antibacterial and antioxidant properties. Although the traditional preservation technology had a good effect on fresh aquatic products, their preservation performance was limited. The shelf life of fresh aquatic products could be prolonged by the use of plastic wrap and preservation gaskets, which had biological preservatives with antibacterial and antioxidant properties. In a word, a new preservation material with high efficiency and long-term preservation performance can be obtained through the combination of plastic wrap, preservation gaskets and biological preservation agent, which can improve the freshness quality of fresh aquatic products and have a bright development prospect.
