Abstract: This research developed biodegradable packaging materials for fresh-cut artichokes using the waste of globe artichokes. The extraction of film-forming materials (cellulose, hemicellulose, lignin, and wax fractions) was done with a mild alkaline extraction method. An environmentally friendly mechanical grinding method (Masuko Supermasscolloider) was chosen to produce cellulose microfibrils having 50–200 μm length and 10–30 μm width. The presence of micro fibrillated cellulose in films hindered the heat sealing ability, so using microfibrillated cellulose and Carboxymethyl cellulose together in films (with glycerol, stearic acid, and wax incorporation) exhibited better performance. Micro fibrillated cellulose and Carboxymethyl cellulose-based films have good elasticity (16 % strain), tensile strength (0.85 kg/mm), and seal ability (at 170–220 °C). Scanning Electron Microscope analyses showed films with smooth surfaces and dense structures (from the cross-sectional area). © 2023
