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 μg/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 × 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.

基于羧甲基壳聚糖-阿拉伯胶的柠檬酸和樟脑多酚复合膜的开发用于活性食品包装

在本研究中,羧甲基壳聚糖与阿拉伯树胶 (CG) 为基础的新型功能膜,含有樟脑成功制备了不同浓度(0.5、1.2 和 2% w/w)的种子提取物(CCSE)。此外,通过液相色谱和电喷雾电离四极杆飞行时间质谱 (LC-ESI-QTOF-MS) 鉴定出 16 种酚类化合物,其中最丰富的有机酸是柠檬酸(以 1062.55 μg/g 干重存在于CCSE)。得到的 CG-ANC.P 薄膜在物理化学性质、形态特征、分子性质、熔融和生物活性性质(抗菌、抗氧化和生物降解性)方面进行了综合表征。CCSE 包含在 CG 中导致拉伸性能显着增加 (33.01–63.23 MPa),并具有最佳厚度。溶胀度、水溶性和水蒸气渗透性显着(p < 0.05) 分别从 54.21 降低到 31.70%、32.05 降低到 14.02% 和 3.46 降低到 1.12 × 10 -11  g -1  s -1  Pa -1。开放对照和 CG 样品显示葵花油的过氧化值要高得多(分别为 69.49 ± 0.68 和 20.15 ± 0.31 mEq/kg),而 CG-CCSE2 在孵育 28 天后表现出低值(9.79 ± 0.28 mEq/kg)。添加CCSE(2%)的CG可生物降解薄膜是生产具有抗氧化和抗菌性能的功能性薄膜的最佳选择。
