Aqueous extract of fruit obtained from enriched with phenolic components was used for the first time to fabricate chitosan (CS) and sodium alginate (SA)-based edible films. The edible films supplemented with Ficus fruit aqueous extract (FFE) were characterized physiochemically (using Fourier transform infrared spectroscopy (FT-IR), Texture analyser (TA), Thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray diffraction (XRD), and colourimeter) and biologically (using antioxidant assays). CS-SA-FFA films showed high thermal stability and high antioxidant properties. The addition of FFA into CS-SA film decreased transparency, crystallinity, tensile strength (TS), and water vapour permeability (WVP) but ameliorate moisture content (MC), elongation at break (EAB) and film thickness. The overall increase in thermal stability and antioxidant property of CS-SA-FFA films demonstrated that FFA could be alternatively used as a potent natural plant-based extract for the development of food packaging material with improved physicochemical and antioxidant properties.
首次使用富含酚类成分的果实水提取物制备基于壳聚糖（CS）和海藻酸钠（SA）的可食用薄膜。对添加了无花果果实水提取物（FFE）的可食用薄膜进行了物理化学表征（使用傅里叶变换红外光谱（FT-IR）、质地分析仪（TA）、热重分析（TGA）、扫描电子显微镜（SEM）、X射线衍射（XRD）和色差仪）和生物学表征（使用抗氧化测定）。CS-SA-FFA薄膜表现出高的热稳定性和高抗氧化性能。向CS-SA薄膜中添加FFA降低了透明度、结晶度、拉伸强度（TS）和水蒸气透过率（WVP），但改善了水分含量（MC）、断裂伸长率（EAB）和薄膜厚度。CS-SA-FFA薄膜热稳定性和抗氧化性能的总体提高表明，FFA可作为一种有效的天然植物提取物，用于开发具有改善的物理化学和抗氧化性能的食品包装材料。
