Abstract：
As a translucent functional gel with biodegradability, non-toxicity and acid resistance, gellan gum has been widely used in probiotic packaging, drug delivery, wound dressing, metal ion adsorption and other fields in recent years. Because of its remarkable gelation characteristics, gellan gum is suitable as the shell material of microcapsules to encapsulate functional substances, by which the functional components can improve stability and achieve delayed release. In recent years, many academically or commercially reliable products have rapidly emerged, but there is still a lack of relevant reports on in-depth research and systematic summaries regarding the process of microcapsule formation and its corresponding mechanisms. To address this challenge, this review focuses on the formation process and applications of gellan gum-based microcapsules, and details the commonly used preparation methods in microcapsule production. Additionally, it explores the impact of factors such as ion types, ion strength, temperature, pH, and others present in the solution on the performance of the microcapsules. On this basis, it summarizes and analyzes the prospects of gellan gum-based microcapsule products. The comprehensive insights from this review are expected to provide inspiration and design ideas for researchers.
摘要：
作为一种具有生物降解性的半透明功能凝胶，无毒和耐酸，结冷胶已广泛用于益生菌包装，药物输送,伤口敷料,近年来在金属离子吸附等领域。由于其显著的凝胶化特性,结冷胶适合作为微胶囊的外壳材料来封装功能性物质，通过这些功能组分可以提高稳定性并实现延迟释放。近年来,许多学术或商业上可靠的产品迅速出现，但是关于微胶囊形成过程及其相应机制的深入研究和系统总结，仍然缺乏相关报道。为了应对这一挑战，本文综述了结冷胶基微胶囊的形成过程和应用,并详细介绍了微胶囊生产中常用的制备方法。此外,它探讨了离子类型等因素的影响，离子强度,温度,pH值,和其他存在于溶液中的微胶囊的性能。在此基础上,总结分析了结冷胶微胶囊产品的发展前景。这篇综述的全面见解有望为研究人员提供灵感和设计思路。
