: Encapsulation, in particular extrusion and co-extrusion, is a common practice to protect probiotics from the harsh conditions of the digestive tract as well as processing. Hydrocolloids, including proteins and carbohydrates, natural or modified, are a group of ingredients used as the wall material in extrusion. Hydrocolloids, due to their specific properties, can significantly improve the probiotic survivability of the final powder during the microencapsulation process and storage. The present article will discuss the different kinds of hydrocolloids used for microencapsulation of probiotics by extrusion and co-extrusion, along with new sources of novel gums and their potential as wall material.

挤出和共挤出：一种用替代材料封装益生菌的技术

：封装，特别是挤压和共挤压，是保护益生菌免受消化道和加工恶劣条件影响的常见做法。亲水胶体，包括天然或改性的蛋白质和碳水化合物，是一组在挤出中用作壁材料的成分。亲水胶体由于其特定的性质，可以显着提高最终粉末在微囊化过程和储存过程中的益生菌存活率。本文将讨论通过挤出和共挤出用于益生菌微囊化的不同种类的水胶体，以及新型树胶的新来源及其作为壁材料的潜力。
