Mixed monolayers of gluten-emulsifiers at the air-water interface

The interactions and miscibility analysis of gluten-emulsifiers mixed film show that those films are not completely miscible as demonstrated by the presence of both two transition zones and also by the deviation of the mean molecular areas of mixed films from the values calculated according to the rule of additivity (GAINES, 1966). Furthermore, the free energy excess of mixing is positive in presence of emulsifiers, confirming the partial miscibility of gluten emulsifier monolayers.
