Physicochemical and antimicrobial properties of bovine and salmon gelatin-chitosan films

The aim was to study thermo-physical and antimicrobial properties of gelatin-chitosan films by gelatin origin (bovine and salmon), chitosan concentration and physical state (glassy or rubbery). Thermo-physical properties (pH, Bloom grade, color, isotherms, glass transition temperature, moisture upta...
