Natural hydrogels such as alginate are hopeful gadgets for cellular encapsulation, drug delivery, and many others because of their properties, such as biodegradable and non-toxic for the environment. Probiotics, as intestinal microbiota, have numerous benefits for the host's health. On the other hand, the survival of probiotics is critical, especially in the food and medicine industry, and probiotics should endure disagreeable status that occurs in passing through the gastrointestinal system. Encapsulation can be applied to protect probiotics but increase their bio-accessibility, so the survival rate of bacteria and their transportation to different body parts. In this review, the literature on delivery systems results focuses on combining alginates with other biopolymers to produce hydrogels that enclose probiotics, only increasing their encapsulation performance and survival compared to alginates in gastrointestinal simulation conditions collected. All the tastes and limitations, along with the benefits of microencapsulation of probiotics using hydrogels, can lead to the emergence of biopolymers, new ways of protecting probiotics, and ultimately producing products that are safe for consumers.

海藻酸盐等天然水凝胶因其可生物降解和对环境无毒等特性而有望用于细胞封装、药物输送和许多其他领域。益生菌作为肠道微生物群，对宿主的健康有很多好处。另一方面，益生菌的生存至关重要，尤其是在食品和医药行业，益生菌要经受住胃肠道系统中出现的不良状态。封装可用于保护益生菌但增加其生物可及性，因此细菌的存活率及其向不同身体部位的运输。在这篇综述中，关于递送系统结果的文献侧重于将藻酸盐与其他生物聚合物结合以生产包裹益生菌的水凝胶，与收集的胃肠道模拟条件下的藻酸盐相比，仅增加了它们的封装性能和存活率。所有的口味和限制，以及使用水凝胶对益生菌进行微囊化的好处，都可能导致生物聚合物的出现、保护益生菌的新方法，并最终生产出对消费者安全的产品。
