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_lag 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.

进行比较研究是为了评估最合适的棕榈酸抗坏血酸酯（AP）的基质聚合物。将抗氧化剂（1％和2％w / w）加入基于多糖（阿拉伯胶（GAR），辛烯基琥珀酸酐改性的淀粉（OSA），水溶性大豆多糖（WSSP））和明胶（75％/ 25％）的混合膜中凝胶）。AP以纵向晶体和微球形式存在于膜中。由于具有两亲性，因此AP对薄膜具有保湿作用。然而，其添加降低了膜在水中的溶解度。AP不影响基于OSA的载体的水蒸气渗透性和抗张强度。T_滞后的Makoid-Banakar该模型适用于有效模拟胶片中AP的释放。基于OSA的系统提供了最快的AP释放，因此具有最佳的初始抗自由基活性。添加1％AP的GAR75 / GEL25膜可提供最长的抗氧化剂释放时间。
