Octenyl succinic anhydride (OSA)-modified starch and maltodextrins (MDs) are important carbohydrate polymers as wall materials. However, few studies have shown whether these two wall materials affect the composition of core materials. In this work, we investigated the effects of OSA-modified starch and MD on the release property of essential oils. Results showed that among the seven characteristic aroma components (CACs) of rose essential oil (REO), the esters released the fastest, followed by the alcohols, while the release of the phenols was the slowest. Environmental factors such as temperature and relative humidities (RHs) had significant influences on the release kinetics of CACs in REO. This work provides new insights into the use of OSA-modified starch and MDs as wall materials for encapsulating complex and bioactive components.
辛烯基琥珀酸酐（OSA）改性淀粉和麦芽糊精（MD）是重要的碳水化合物聚合物，可用作壁材。然而，很少有研究表明这两种壁材是否会影响芯材的组成。在这项工作中，我们研究了 OSA 改性淀粉和 MD 对精油释放性能的影响。结果表明，在玫瑰精油（REO）的 7 种特征香气成分（CACs）中，酯类释放最快，其次是醇类，而酚类释放最慢。环境因素，如温度和相对湿度（RHs），对 REO 中 CACs 的释放动力学有显著影响。这项工作为 OSA 改性淀粉和 MD 用作包埋复杂和生物活性成分的壁材提供了新的见解。
