In this study, biocomposite edible films of gamma-aminobutyric acid (GABA)-rich fermented soy protein (GABA-RFSP) with different chitosan concentrations (2, 2.5, and 3%) were prepared. The GABA-rich edible films based on 2.5 % chitosan had the highest a*, b*, browning index, and absorbance at 420 nm compared to other films, indicating the occurrence of Maillard reaction during film-formation period. The Maillard reaction fabricated 2.5 % chitosan-based edible films with high tensile strength and elongation at break, in c
