摘　　要：海藻酸是从褐藻中提取的一种海洋源生物高分子,广泛应用于食品配料、医卫材料、生物工程、纺织工程、功能助剂等领域。为了推广海藻酸在更多领域的应用、改善其使用功效,本文总结了通过酯化、氧化、磷酸化、硫酸化、酰胺化、接枝共聚等改性技术获得的各种海藻酸衍生制品的结构、性能和应用。结果显示功能化改性过程中产生的结构多样性有效提高了海藻酸的性能和使用功效,对新产品开发有重要的应用价值。Alginate is a marine biopolymer extracted from brown seaweeds that is widely used in food ingredients, biomedical materials, bio-engineering, textile en-gineering, functional additives and many other industries. In order to promote the applications of alginate in more fields and improve its efficacy, this paper summarized the structure, properties and applications of various alginate derived products obtained through functional modifications such as esterification, oxidation, phosphorylation, sulfation, amidation and graft co-polymerization. Results showed that the structural diversity generated during the functional modification process can effectively improve the properties and efficacy of alginate, which is highly valuable for new product development.
