静电纺丝技术包埋天然酚类化合物研究进展

天然酚类化合物因其对人体健康具有众多益处，近年来在食品、营养学和医药等领域得到了广泛的关注。然而，酚类化合物较差的溶解性、稳定性和生物利用度等严重地限制了其应用。如何有效地保护和运载这些酚类化合物并保持其生物活性成为研究的热点问题。静电纺丝是一种易于操作且成本低廉的纳米级纤维制备技术，所制备的纳米纤维可作为纳米载体对生物活性物质进行包埋和控制释放，因此可作为包埋酚类化合物的一种有效方法。本文概述了静电纺丝技术的基本原理、类型、影响参数、常用的聚合物基质和优势，对静电纺丝技术包埋天然酚类化合物的相关研究进行了综述，最后展望了其在食品工业的应用前景，以期为静电纺丝技术在食品领域应用提供一定的理论指导。

Progress in the Encapsulation of Natural Phenolic Compounds by Electrospinning

Natural phenolic compounds have gained much attention in food, nutraceutical, pharmaceutical and other fields in recent years because of their benefits on human health. However, the application of phenolic compounds is limited due to their poor solubility, stability, and bioavailability. How to protect and deliver these compounds effectively and to maintain their functional properties has become a research hotspot. Electrospinning is a simple and low-cost technique to produce nanofibers, which can serve as nanovehicles for the encapsulation and controlled release of bioactive compounds. It can be used as an effective method to encapsulate phenolic compounds. This review presents an overview of the fundamental principle, types and operating parameters of electrospinning, the polymer matrices commonly used in electrospinning and the advantages of electrospinning, and it summarizes recent studies investigating the application of electrospinning in the encapsulation of phenolic compounds. Finally, future prospects for its application in the food industry are discussed, which will provide theoretical guidance for the application of electrospinning in the food industry.
