Extrusion of gelatin-based composite films: effects of processing temperature and pH of film forming solution on mechanical and barrier properties of manufactured films

The composite films, gelatin incorporated with corn oil were manufactured using a twin-screw co-rotating extruder. The effect of extrusion temperature (90, 105, 120 and 130°C) and film forming pH values (5.7–8.7) on the mechanical and barrier properties of gelatin-based composite films were investig...
