产胞外多糖（EPS）的乳酸菌（LAB）在乳制品工业中发挥着重要作用，因为它们对发酵乳制品的稠度和流变性做出了贡献。EPS聚合物可以被认为是天然生物增稠剂，因为它们是由具有公认安全状态（GRAS）的LAB起始剂原位产生的。EPS的物理化学性质决定了其增粘效率。因此，这些生物聚合物的结构-功能关系的知识是至关重要的，以便选择或设计用于特定技术应用的聚合物。此外，这些EPS中的一些还具有健康益处，特别是抗肿瘤和免疫调节活性。也有人提出了益生元的作用。然而，几乎所有的研究都是在体外进行的，关于口服给药的体内实验的信息很少。本文综述了乳酸菌EPS的功能特性，包括技术和健康促进方面的最新信息。(C)2002爱思唯尔科技有限公司版权所有。
Lactic acid bacteria (LAB) that produce exopolysaccharides (EPSs) play an important role in the dairy industry because of their contribution to the consistency and rheology of fermented milk products. The EPS polymers can be considered as natural biothickeners because they are produced in situ by the LAB-starters that have General Recognised As Safe status (GRAS). The physico-chemical properties of EPSs determine their viscosifying efficiency. Hence, the knowledge of the structure-function relationship of these biopolymers is crucial in order to choose or design polymers for a specific technological application. In addition, health benefits have been attributed to some of these EPSs, particularly antitumor and immunomodulating activities. Also a prebiotic role has been suggested. However, almost all studies were performed in vitro and scarce information is available concerning in vivo experiments with oral administration. This overview focuses on the recent information about the functional properties of lactic acid bacterial EPSs, including both technological and health-promoting aspects.
