The growing consumer demand for foods that do not contain artificial additives and are “clean labeled” can be addressed in fermented products by using lactic acid bacteria (LAB) capable of synthesizing exopolysaccharides (EPS). There is great variability in LAB-based EPS in terms of quantity, monomer composition, molecular weight, charge, and structure, which results in an array of physicochemical and rheological properties that can be exploited for varied applications in the food industry.

EPS are an alternative class of bio-thickeners widely used in the food industry. This review provides a brief overview of EPS composition and production, and highlights EPS functionality, focusing on specific areas and ways of applying them in food products.

Although EPS-producing LAB strains have been traditionally applied in the manufacture of cultured milks …
