摘　　要：植物多糖是存在于植物中的一类天然大分子聚合物,具有抗氧化、降血糖、免疫调节、抗肿瘤、抑菌等多种生物活性。大量研究发现多糖可以通过结构修饰增加其生物活性,本文重点介绍了硫酸化、磷酸化、乙酰化、羧甲基化和硒化等五种化学修饰多糖方法及各方法对多糖生物活性的影响,同时总结了化学修饰多糖作为食品添加剂、食品包装材料、食品功能因子和运载体及食品配料等应用。这为充分挖掘植物多糖生物活性,推动其在食品领域的产品开发和研究提供理论参考。Plant polysaccharides represent a class of naturally occurring macromolecular polymers that exhibit diverse bioactivities,including antioxidant,hypoglycemic,immunomodulatory,antitumor,and antibacterial.A burgeoning body of research suggests that polysaccharide bioactivities can be enhanced via structural modifications.This study presents five chemical modification methods for polysaccharides—sulfation,phosphorylation,acetylation,carboxymethylation,and selenization—with particular emphasis on their effects on polysaccharide bioactivities.Furthermore,it summarizes the applications of chemically modified polysaccharides as food additives,edible packaging materials,functional food components,carriers,and food ingredients.This information provides a theoretical framework to fully investigate the bioactivities of plant polysaccharides and advance their product development and research in the food industry.
