Research Progress on the Application of Preservation Techniques for Aquatic Products

Being rich in high-quality proteins and polyunsaturated fatty acids, aquatic products are susceptible to microorganisms and endogenous enzymes during storage and processing, resulting in quality deterioration such as fat oxidation. Therefore, it is necessary to carry out research to develop preservation methods for aquatic products. This paper presents the latest progress on preservation methods for aquatic products, illustrates the current status of the application of physical, chemical and biological preservation methods to aquatic products, summarizes the shortcomings of these reservation methods, and proposes possible solutions. It is concluded that the optimum combination of different preservation methods to extend the shelf life of aquatic products can be discovered based on the principle of hurdle technology. Finally, an outlook on future trends in the preservation of aquatic products is given. We expect that this review will provide theoretical reference for efficient freshness preservation and quality improvement of aquatic products.
