This paper reports the synthesis of a novel edible film from Balangu seed mucilage (BSM) as a new carbohydrate source. Optimal formulation of the proposed edible film was found through fabricating several distinct films with different concentrations of BSM and glycerol. The effect of these formulation variables on the physical, mechanical, thermal, barrier, and microstructural properties of the manufactured films was then investigated. Optimal formulation of the BSM edible film was then determined based on the measured mechanical and barrier characteristics. These characteristics were found to deteriorate with an excessive use of glycerol which caused non-homogeneity of the films as observed through scanning electron micrographs. In-depth analysis of the optimal BSM film properties was performed through investigating its oxygen permeability, Fourier transform infrared spectroscopy, atomic force microscopy, X-ray diffraction, and water sorption isotherm. The superior mechanical and barrier characteristics of the obtained optimal BSM edible film make it a potential candidate for packaging that aim at an extended shelf-life.
本文报道了一种新型可食用膜的合成，该膜由巴兰果种子粘胶（BSM）作为一种新的碳水化合物来源。通过制备几种不同浓度的 BSM 和甘油的不同薄膜，找到了最佳的薄膜配方。然后研究了这些配方变量对所制薄膜的物理、机械、热、阻隔和微观结构性能的影响。根据机械和阻隔特性的测量，确定了 BSM 可食用膜的最佳配方。发现随着甘油用量的增加，薄膜的机械和阻隔性能会恶化，这可以通过扫描电子显微镜观察到薄膜的不均匀性来证明。通过研究其氧气透过率、傅里叶变换红外光谱、原子力显微镜、X 射线衍射和水分吸附等温线，对最佳 BSM 薄膜性能进行了深入分析。所得到的最佳 BSM 可食用膜具有优异的机械和阻隔性能，使其成为具有延长货架期目标的包装的潜在候选材料。
