摘要
Probiotics are active microorganisms that are beneficial to the health of the host. However, probiotics are highly sensitive to the external environment, and are susceptible to a variety of factors that reduce their activity during production, storage, and use. Microencapsulation is an effective method that enhances probiotic activity. Macromolecules like polysaccharides, who classified as biologically active prebiotics, have attracted significant attention for their utility in probiotic microencapsulation. This article summarized the types of commonly used microencapsulation materials and their structural characteristics from the perspective of polysaccharides prebiotics. It also discussed recent advancements, probiotic-prebiotic microcapsule-based modulation of the immune system, as well as the associated limitations. Furthermore, the advantages and disadvantages of eight prebiotics as microencapsulation wall materials. The honeycomb structure of β-glucan enhances the bioavailability of probiotics, while, fructooligosaccharide and galactooligosaccharides improve microbead structure to tightly encapsulate probiotics. The terminal reducing groups of isomaltooligosaccharides and the free hydroxyl groups in xylooligosaccharides also positively affect the structure of microcapsules. Prebiotics not only enhance the survival rate and biological activity of probiotics as embedding materials during storage, but also exert their own probiotic effects. Collectively, prebiotics holds great promise as microencapsulation materials for probiotics delivery.
