生鲜水产品保鲜膜和保鲜衬垫的应用及研究进展

目的 阐明提高生鲜水产品贮藏保鲜性能的适用方法，指出现有水产品保鲜技术和保鲜材料存在的问题及不足，对未来生鲜水产品保鲜材料的发展作出展望性分析。方法 介绍生鲜水产品保鲜常用的物理、化学和生物保鲜技术的优势和不足。从分类、应用范围及抗菌、抗氧化等性能多角度出发分析保鲜膜、保鲜衬垫的研究现状。结果 传统的保鲜技术虽对生鲜水产品有一定的保鲜作用，但其保鲜性能有限，保鲜膜、保鲜衬垫辅以抗菌、抗氧化等性能的生物保鲜剂，可延长生鲜水产品的货架期。结论 保鲜膜、保鲜衬垫同生物保鲜剂联合使用，以获得具有高效、长效保鲜性能的新型保鲜材料，提高了生鲜水产品的鲜度品质。新型保鲜材料具有广阔的发展前景。

Application and Research Progress of Plastic Wrap and Preservation Gasket for Fresh Aquatic Products

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.
