Alginate is a naturally occurring polysaccharide used in the bio industry. It is mainly derived from brown algae species. Alginate-based edible coatings and films attract interest for improving/maintaining quality and extending the shelf-life of fruit, vegetable, meat, poultry, seafood, and cheese by reducing dehydration (as sacrificial moisture agent), controlling respiration, enhancing product appearance, improving mechanical properties, etc. This paper reviews the most recent essential information about alginate-based edible coatings. The categorization of alginate-based coatings/film in food packaging concept is formed gradually with the explanation of the most important titles. Emphasis will be placed on active ingredients incorporated into alginate-based formulations, edible coating/film application methods, research and development studies of coated food products and mass transfer and barrier characteristics of the alginate-based coatings/films. Future trends are also reviewed to identify research gaps and recommend new research areas. The summarized information presented in this article will enable researchers to thoroughly understand the fundamentals of the coating process and to develop alginate-based edible films and coatings more readily.
海藻酸盐是一种天然存在的多糖，用于生物产业。它主要来源于褐藻物种。基于海藻酸盐的可食用涂层和薄膜因通过减少脱水（作为牺牲性保湿剂）、控制呼吸、提升产品外观、改善机械性能等方式来提高/保持水果、蔬菜、肉类、家禽、海鲜和奶酪的品质并延长其保质期而受到关注。本文综述了有关基于海藻酸盐的可食用涂层的最新重要信息。基于海藻酸盐的涂层/薄膜在食品包装概念中的分类是随着最重要主题的阐释而逐渐形成的。重点将放在纳入基于海藻酸盐配方中的活性成分、可食用涂层/薄膜的应用方法、涂覆食品的研发研究以及基于海藻酸盐的涂层/薄膜的传质和阻隔特性上。还对未来趋势进行了综述，以确定研究差距并推荐新的研究领域。本文呈现的总结信息将使研究人员能够透彻理解涂层工艺的基本原理，并更轻松地开发基于海藻酸盐的可食用薄膜和涂层。
