产胞外多糖（eps）的乳酸菌（LAB）和双歧杆菌因其技术优势被广泛用作发酵食品的发酵剂。此外，lab - eps和bifido- eps已被证明具有多种生理功能，如抗氧化、抗癌、抗菌和免疫活性，其中免疫调节活性近年来引起了许多科学研究的兴趣。一般来说，这些功能与eps的化学组成和构型密切相关。本文就lab - eps和bifido- eps的结构和功能作一综述。其中，详细综述了体外和体内用于评价eps免疫作用的模型，重点介绍了eps的结构-免疫关系。此外，本文还详细讨论了eps在食品工业中的应用，特别是eps在酸奶质地中的不同作用。最后，提出了一些eps生产策略，为eps产量的提高提供参考。
Exopolysaccharides (EPSs)-producing lactic acid bacteria (LAB) andBifidobacteriaare widely used as starter cultures to make fermented food products due to their technological benefits. Moreover, LAB-EPSs and bifido-EPSs have been demonstrated to possess various physiological functions such as antioxidant, anticancer, antibacterial and immunological activities, among which the immunoregulatory activity has attracted a lot of scientific interests in recent years. Generally, these functions are closely related to the chemical compositions and configurations of EPSs. This review sheds light on structures and functions of LAB-EPSs and bifido-EPSs. Among them, in vitro and in vivo models used to evaluate the immune effects of EPSs are summarized in detail, with particular emphasis on the structure-immunity relationship of EPSs. Furthermore, the applications of EPSs in the food industry, especially the different roles EPSs played in the yogurt texture, are discussed carefully in this review. Finally, some strategies of EPSs production are also proposed to provide some information about the enhancement of EPSs yield.
