Influence of heating, protein and glycerol concentrations of film-forming solution on the film properties of Argentine anchovy (Engraulis anchoita) protein isolate

► This study showed homogeneous and flexible films prepared from API. ► The films with less API content and temperature had lower solubility in water. ► Higher glycerol concentration resulted in a film with greater elongation. ► Lower temperature and protein and glycerol content resulted in a resistant film. ► Higher temperature resulted in a film with a rough surface and less homogeneous.
