Their production significantly contributes to texture, mouth feel, teats and stability of the final dairy product. Recently, it is observed that the consumer demand for products with low fat or sugar content and low levels of food additives, as well as cost factors, make microbial EPS a viable alternative of artificial food additives. To reduce the amount of added milk solids, to improve viscosity, to enhance texture and mouth feel and to avoid syneresis during fermentation or upon storage of the fermented dairy products, EPS producing functional starters have valuable applications in fermentation based dairy industries. It is studied that yogurt made with EPS producing starter cultures has better water binding capacity, which decreases the process of syneresis (whey separation) (Amatayakul et al., 2005).
