Fucoidans are promising sulfated polysaccharides isolated from marine sources that have piqued the interest of scientists in recent years due to their widespread use as a bioactive substance. Bioactive coatings and films, unsurprisingly, have seized these substances to create novel, culinary, therapeutic, and diagnostic bioactive nanomaterials. The applications of fucoidan and its composite nanomaterials have a wide variety of food as well as pharmacological properties, including anti-oxidative, anti-inflammatory, anti-cancer, anti-thrombic, anti-coagulant, immunoregulatory, and anti-viral properties. Blends of fucoidan with other biopolymers such as chitosan, alginate, curdlan, starch, etc., have shown promising coating and film-forming capabilities. A blending of biopolymers is a recommended approach to improve their anticipated properties. This review focuses on the fundamental knowledge and current development of fucoidan, fucoidan-based composite material for bioactive coatings and films, and their biological properties. In this article, fucoidan-based edible bioactive coatings and films expressed excellent mechanical strength that can prolong the shelf-life of food products and maintain their biodegradability. Additionally, these coatings and films showed numerous applications in the biomedical field and contribute to the economy. We hope this review can deliver the theoretical basis for the development of fucoidan-based bioactive material and films.
褐藻胶是一种有前途的硫酸多糖，从海洋资源中分离出来，近年来由于其作为生物活性物质的广泛应用引起了科学家的兴趣。生物活性涂层和薄膜毫不奇怪地利用这些物质来创造新型的、烹饪用的、治疗用的和诊断用的生物活性纳米材料。褐藻胶及其复合材料的应用具有广泛的食品和药理学特性，包括抗氧化、抗炎、抗癌、抗血栓、抗凝、免疫调节和抗病毒特性。褐藻胶与其他生物聚合物如壳聚糖、藻酸盐、结冷胶、淀粉等的混合物显示出有前途的涂层和成膜能力。混合生物聚合物是改善其预期性能的推荐方法。本文综述了褐藻胶的基础知识和最新发展，以及基于褐藻胶的生物活性涂层和薄膜复合材料及其生物学特性。在本文中，基于褐藻胶的可食用生物活性涂层和薄膜表现出优异的机械强度，可以延长食品的保质期并保持其可生物降解性。此外，这些涂层和薄膜在生物医学领域有许多应用，并为经济做出了贡献。我们希望这篇综述能为基于褐藻胶的生物活性材料和薄膜的开发提供理论基础。
