Physicochemical characterisation of enzymatically hydrolysed derivatives of acetylated starch

► Enzymatic hydrolysis of acetylated starch in membrane reactor. ► The influence of conditions of process on the surface-active properties of hydrolysates. ► Mixed adsorbed monolayer at the air/water interface for hydrocolloid-surfactant systems. ► Synergism in reducing the surface tension at the air/water interface.
