摘　　要：益生菌广泛应用于畜禽养殖,但益生菌在保存及使用中会受到外界逆境条件影响,导致其活性降低甚至死亡。微囊化包被技术已经被应用于对益生菌的保护中。本文综述了益生菌微囊化包被的蛋白类、多糖类、改性淀粉和纳米壁材,分析了挤压法、喷雾干燥法、冷冻干燥法、乳化法、复凝聚法等益生菌微囊化包被的方法,阐述了微胶囊化包被对益生菌耐酸、耐高温、耐湿等抗逆特性和耐贮存的作用效果,最后对微囊化包被技术在饲用益生菌上的应用前景进行了展望。Probiotics are widely used in animal feeding.However,they are affected by adverse environmental condition during storage or use,resulting in reduced activity or even death.Microencapsulation has been used in protection of probiotics.This article reviews the common adverse environment that the probiotics face.We present the main wall materials used in microencapsulation such asproteins,polysaccharides,modified starch and nanomaterials.The article reviews methods for probiotics microencapsulation including extrusion,spray drying,freeze drying,emulsification,complex coacervation and so on.We also reviewed the effects of microencapsulation on the resistance of probiotics to acid,high temperature,humidity and store.instorage.Finally,the future was prospected for microencapsulation used in feed probiotics industry.
