Lactic acid bacteria (LAB) used in the food industry, mainly for the production of dairy products, are able to synthetize exopolysaccharides (EPS). EPS play a central role in the assessment of rheological and sensory characteristics of dairy products since they positively influence texture and organoleptic properties. Besides these, EPS have gained relevant interest for pharmacological and nutraceutical applications due to their biocompatibility, non-toxicity and biodegradability. These bioactive compounds may act as antioxidant, cholesterol-lowering, antimicrobial and prebiotic agents. This review provides an overview of exopolysaccharide-producing LAB, with an insight on the factors affecting EPS production, their dairy industrial applications and health benefits.
食品工业中使用的乳酸菌(LAB)主要用于生产乳制品,它们能够合成胞外多糖(EPS)。由于EPS对乳制品的质地和感官特性有积极影响,因此在评估乳制品的流变学和感官特性方面起着核心作用。除此之外,由于其生物相容性、无毒性和可生物降解性,EPS在药理学和营养保健品应用方面也引起了相关关注。这些生物活性化合物可能作为抗氧化剂、降胆固醇剂、抗菌剂和益生元。本文综述了产胞外多糖的乳酸菌,深入探讨了影响EPS产生的因素、它们在乳制品工业中的应用以及对健康的益处。
