The rheological properties (apparent viscosity and elastic
modulus) and physical properties (syneresis) of the set yoghurts
are generally governed by the protein network. The presence of
EPS-producing lactic acid bacteria made an additional contribution
to the rheological and physical properties but at different levels
depending on their structural characteristics. The presence of the
anionic, linear and stiff EPS from ST1 starter increased the apparent
viscosity and the elastic modulus values of yoghurt without starch
