壳聚糖与生物保鲜剂复合使用在水产品保鲜中的研究进展

壳聚糖作为自然界中存在的第二大天然高分子物质,已被广泛应用于食品、医药、环保、工业、化妆品、纺织等领域.在食品加工中,壳聚糖可以抑制水产品中微生物的生长,因此常用于水产品保鲜.但单独使用壳聚糖进行保鲜时,有抗氧化性低、感官品质差等特点,故在实际应用中常加入其他物质进行复合保鲜.生物保鲜剂是从自然界中提取或利用生物工程技...

Research Progress in the Application of Chitosan and Biological Preservative in Aquatic Products Preservation

As the second largest natural polymer substance in nature,chitosan has been widely used in food,medicine,environmental protection,industry,cosmetics,textile and other fields.In food processing,chitosan can inhibit the growth of microorganisms in aquatic products,so it is often used in the preservation of aquatic products.However,when chitosan is used alone for fresh-keeping,it has the characteristics of low oxidation resistance and poor sensory quality,so other substances are often added for compound fresh-keeping in practical application.Biological preservative is a new preservative extracted from nature or obtained by using biological engineering technology.It has the characteristics of high efficiency and green.Therefore,in recent years,the technology of chitosan combined with other biological preservatives to keep aquatic products fresh has attracted extensive attention of researchers.Therefore,the preservation properties and mechanism of natural chitosan were described,and the application of chitosan and other biological preservatives in the preservation of aquatic products was reviewed.The existing problems were analyzed and the possible solutions were put forward.Meanwhile,the development prospect of chitosan compound biological preservative in the preservation of aquatic products was prospected.
