摘要： In this study, carboxymethyl chitosan with gum Arabic (CG) based novel functional films containing Cinnamomum camphora seeds extract (CCSE) at varying concentrations (0.5, 1.2 and 2% in w/w) were successfully fabricated. Moreover, sixteen phenolic compounds were identified by liquid chromatography and electrospray-ionized quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS) and the most abundant organic acid was citric acid (present at 1062.55 mu g/g dry weight in CCSE). The resulting CG-ANC.P film was comprehensively characterized in terms of physicochemical properties, morphological characteristics, molecular properties, melting, and bioactivities properties (antimicrobial, antioxidant and biodegradability). CCSE inclusion into CG resulted in a marked increase (33.01-63.23 MPa) of tensile properties, with optimum thickness. The swelling degree, water solubility, and water vapor permeability were markedly (p < 0.05) reduced from 54.21 to 31.70%, 32.05 to 14.02%, and 3.46 to 1.12 x 10(-11) g(-1) s(-1) Pa-1, respectively. The open control and CG samples showed much higher peroxide values of sunflower oil (69.49 +/- 0.68 and 20.15 +/- 0.31 mEq/kg, respectively) while CG-CCSE2 exhibited a low value (9.79 +/- 0.28 mEq/kg) after 28 days incubation. The CG biodegradable film with the addition of CCSE (2%) was optimal for producing functional films with antioxidant and antibacterial properties.
