Applications of Bioactive Seaweed Substances in Functional Food Products(海藻活性物质在功能食品中的应用)
摘要
Seaweeds are the main ocean plants, which can be used to extract hydrocolloids such as alginate, carrageenan and agar, and many types of bioactive seaweed substances such as fucoidan, seaweed iodine, mannitol, vitamins, polyphenol and minerals. Seaweed polysaccharides and their derivatives such as alginate, carrageenan, agar, oligosaccharides, fucoidan and propylene glycol alginate had gelling, thickening, emulsifying, film forming and many other unique properties which could help improve gastrointestinal systems, and act as antioxidants with related excellent health benefits. They were widely used and highly valued in the development and production of marine functional foods, and were the key areas of research and development in marine functional food products. In this paper, the physicochemical properties and biological activities of algal gum represented by hydromoronate, carrageenan and agaricone as well as algal active substances represented by petrolatum polysaccharide and algal oligosaccharide were introduced, which was great value to further promote the application of algal active substances in the field of functional foods.(海藻是海洋植物的主体,可提取出海藻酸盐、卡拉胶、琼胶等海藻胶以及岩藻多糖、海藻碘、甘露醇、维生素、多酚、矿物质元素等种类繁多的海藻活性物质。以海藻胶、海藻胶寡糖、岩藻多糖、海藻酸丙二醇酯等为代表的海藻多糖及其衍生物具有凝胶、增稠、乳化、成膜等理化特性和改善胃肠道系统、抗氧化等健康功效,在海洋功能食品的研发、生产中有很高的应用价值,是一类重要的海洋功能性食品配料,其开发利用是当前及今后很长时间内海洋功能食品领域的热点之一。介绍海藻酸盐、卡拉胶、琼胶等为代表的海藻胶以及岩藻多糖、海藻胶寡糖为代表的海藻活性物质的理化性能和生物活性功效,对进一步推广海藻活性物质在功能食品领域的应用有重要价值。)
