In order to solve the problems of low survival rate， low viable number and unsatisfied performance of free probiotic products in vivo， microencapsulation technologies have been widely studied and gradually applied to commercial products these years. This paper focuses on the functional evaluation of microencapsulated probiotic products in vitro and in vitro in recent years， covering the functional characteristics of microencapsulated probiotics such as survival， release， adhesion and antibacterial in vitro， and the functional characteristics of probiotics such as survival， adhesion， colonization， anti-diarrhea， antibacterial， anti-inflammatory， anti-oxidation and regulation of metabolic syndrome in vivo， and provides some suggestion for the further development of effective probiotic products for human beings.
