摘要

本研究开发了基于安息香油胶树脂（BOGR）负载抗氧化明胶/pectin（GEPE）的薄膜，并对各种参数进行了表征，包括机械、阻隔、光学、薄膜亲水性/疏水性、表面粗糙度、化学、热、形态和抗氧化特性。BOGR 的加入降低了水溶性、含水量、拉伸强度和断裂伸长率。然而，透水性、不透明度、厚度和疏水性却有所增加。此外，扫描电镜和原子力显微镜分析证实，与空白薄膜相比，负载了 BOGR 的薄膜显示出异质和粗糙的表面。红外光谱证实了 GEPE 和 BOGR 之间的分子间相互作用。制备的 BOGR 负载薄膜的热稳定性得到了改善。此外，ABTS 和 DPPH 分析表明，随着 BOGR 浓度的增加，薄膜的抗氧化活性显著提高。我们的研究结果表明，负载 BOGR 的复合薄膜可用作食品包装应用的活性材料。

Preparation and characterization of gelatin‐pectin‐based active films incorporated with Styrax benzoin oleo gum resin

In this study, benzoin oleogum resin (BOGR) loaded antioxidant gelatin/pectin (GEPE) based films were developed and characterized for various parameters including mechanical, barrier, optical, film hydrophilicity/hydrophobicity, surface roughness, chemical, thermal, morphological and antioxidant properties. The incorporation of BOGR decreased water solubility, moisture content, tensile strength, and elongation at break. However, water permeability, opacity, thickness, and water hydrophobicity were increased. Moreover, SEM and AFM analysis confirmed that the films loaded with BOGR showed heterogeneous and rougher surfaces in comparison to blank film. The intermolecular interactions between GEPE and BOGR was confirmed by infrared spectroscopy. Thermal stability of the prepared BOGR loaded films was improved. Additionally, antioxidant activities of the film were significantly increased with increase in concentration of BOGR as indicated by ABTS and DPPH assays. Our findings indicate that BOGR loaded composite films could be used as an active material for food packaging applications.

期刊介绍： Polymers for Advanced Technologies is published in response to recent significant changes in the patterns of materials research and development. Worldwide attention has been focused on the critical importance of materials in the creation of new devices and systems. It is now recognized that materials are often the limiting factor in bringing a new technical concept to fruition and that polymers are often the materials of choice in these demanding applications. A significant portion of the polymer research ongoing in the world is directly or indirectly related to the solution of complex, interdisciplinary problems whose successful resolution is necessary for achievement of broad system objectives. Polymers for Advanced Technologies is focused to the interest of scientists and engineers from academia and industry who are participating in these new areas of polymer research and development. It is the intent of this journal to impact the polymer related advanced technologies to meet the challenge of the twenty-first century. Polymers for Advanced Technologies aims at encouraging innovation, invention, imagination and creativity by providing a broad interdisciplinary platform for the presentation of new research and development concepts, theories and results which reflect the changing image and pace of modern polymer science and technology. Polymers for Advanced Technologies aims at becoming the central organ of the new multi-disciplinary polymer oriented materials science of the highest scientific standards. It will publish original research papers on finished studies; communications limited to five typewritten pages plus three illustrations, containing experimental details; review articles of up to 40 pages; letters to the editor and book reviews. Review articles will normally be published by invitation. The Editor-in-Chief welcomes suggestions for reviews.
