Exopolysaccharides (EPS) are complex sugars (polysaccharides) which are secreted mainly by sourdough lactic acid bacteria during the long slow fermentation process. In addition to natural polysaccharides present in cereal grains flour and dough, sourdough bacteria are also involved in production of polysaccharides on sourdough fermentation. Exopolysaccharides can also be considered as source of fibre.
