Abstract: With great concern on aquatic products, fresh-keeping technologies of aquatic products develop rapidly, and it becomes a research trend to seek safe and efficient biopreservation technologies. This paper introduces the principles of biopreservative, and focuses on several commonly used biopreservatives such as chitosan, tea polyphenols, iysozyme and Nisin combining with other preservation technologies on the aquatic products preservation. Finally, it also discusses the development directions of multiplex biopreservation, and current situation of the compound fresh-keeping agents.

Key words: biopreservative technology, multiplex biopreservative, aquatic products

摘要： 随着人们对水产品安全问题的普遍关注，水产品保鲜技术迅速发展，寻求一 种更安全、高效的生物保鲜剂成为水产品保鲜领域的研究趋势。本文综述了生物保 鲜剂的作用机制，重点介绍了一些常用生物保鲜剂如壳聚糖、茶多酚、溶菌酶、乳 酸链球菌素与其他保鲜技术相结合在水产品保鲜中进行的复合应用。并根据目前复 合保鲜剂使用的现状，对利用复合生物保鲜剂保鲜水产品进行了展望。
