壳聚糖、臭氧、海藻酸钠、茶多酚等天然保鲜剂具有无毒无味、可生物降解、生物相容性好、成本较低、保鲜效果显著等诸多优点，正日益成为大宗淡水鱼贮藏保鲜研究的热点。天然保鲜剂的研制，能有效降低水产品贮藏成本，提高经济效益，还可以改善化学保鲜剂残留给人体健康和环境带来诸多负面的影响，具有非常广阔的应用前景。文章介绍了天然保鲜剂保鲜淡水鱼的机理，综述了天然保鲜剂在淡水鱼贮藏保鲜中的最新进展，分析了目前研究中存在的问题并对发展方向作出展望。

Natural antistaling agent, as chitosan, ozone, alginate, tea polyphenols etc, is non-toxic and odorless, biodegradable, biocompatible, low cost, excellent preservation effect, which is becoming a hot on preservation of freshwater fish. Development of natural preservative can not only effectively reduce the cost of storage of aquatic products, promoting economic efficiency, but also improve a lot of negative effects to human health and environment causing by the chemical preservative residual, which has a broad application prospect. The mechanism of natural antistaling agent for freshwater fish was introduced. The applications of natural antistaling agent for the preservation of freshwater fish were reviewed. In addition, some suggestions of the development were presented.
