Emulsifying, rheological and physicochemical properties of exopolysaccharide produced by Bifidobacterium longum subsp. infantis CCUG 52486 and Bifidobacterium infantis NCIMB 702205

► EPS was extracted and purified from two Bifidobacterium strains. ► A porous structure and pseudoplastic fluid behaviour was observed with one of the EPS. ► Both EPS produced more stable emulsions than guar and xanthan gum. ► The EPS of B. longum subsp. infantis has potential applications in the food industry.
