Abstract

The comparative study was performed in order to assess the most suitable matrix polymer for ascorbyl palmitate (AP). The antioxidant (1 and 2% w/w) was loaded into the 75/25 blend films based on polysaccharides (gum Arabic (GAR), octenyl succinic anhydride modified starch (OSA), water soluble soy polysaccharides (WSSP)) and gelatin (GEL). The AP was present in the films both in the form of longitudinal crystals and microglobules. Because of amphiphilic character, the AP had the moisturizing action on the films; however, its addition reduced film solubility in water. AP did not affect the water vapor permeability and tensile strength of the OSA-based carrier. The Makoid-Banakar with T model was suitable for the efficient simulation of AP release from the films. The OSA-based system offered the fastest release of AP and, consequently, had the best initial antiradical activity. The 1%AP-added GAR75/GEL25 film provided the most extended release of antioxidant capacity.

摘要

为了评估适合棕榈酸抗坏血酸酯 (AP) 的基质聚合物，进行了对比研究。抗氧化剂 (1% 和 2%w/w) 被负载到基于多糖 (阿拉伯胶 (GAR)、辛烯基琥珀酸酐改性淀粉 (OSA)、水溶性大豆多糖 (WSSP)) 和明胶 (GEL) 的 75/25 共混膜中。AP 以纵向晶体和微球的形式存在于膜中。由于具有两亲性，AP 对膜具有保湿作用；然而，其添加降低了膜在水中的溶解度。AP 不影响基于 OSA 的载体的水蒸气透过率和拉伸强度。Makoid-Banakar 与 T 模型适用于有效模拟 AP 从膜中的释放。基于 OSA 的系统提供了 AP 的最快释放，因此具有最佳的初始自由基清除活性。添加 1%AP 的 GAR75/GEL25 膜提供了最持久的抗氧化能力释放。
