Abstract:
Starch, a natural polymer, has a complex internal structure. Some starches, such as corn and wheat starches, have well-developed surface pores and internal channels. These channel structures are considered crucial in connecting surface stomata and internal cavities and have adequate space for loading guest molecules. After processing or modification, the starch-containing channel structures can be used for food and drug encapsulation and delivery. This article reviews the formation and determination of starch internal channels, and the influence of different factors (such as starch species and processing conditions) on the channel structure. It also discusses relevant starch preparation methods (physical, chemical, enzymatic, and synergistic), and the encapsulation effect of starch containing internal channels on different substances. In addition, the role of internal channels in regulating the starch digestion rate and other aspects is also discussed here. This review highlights the significant multifunctional applications of starch with a channel structure.
摘要:
淀粉,一种天然聚合物,具有复杂的内部结构。一些淀粉,比如玉米和小麦淀粉,有发达的表面孔隙和内部通道。这些通道结构被认为是连接表面气孔和内腔的关键,并具有足够的空间来加载客体分子。加工或修改后,含淀粉通道结构可用于食品和药物的包封和递送。本文综述了淀粉内部通道的形成和测定,以及不同因素(如淀粉种类和加工条件)对通道结构的影响。它还讨论了相关的淀粉制备方法(物理,化学,酶,和协同作用),以及含淀粉内部通道对不同物质的包封作用。此外,本文还讨论了内部通道在调节淀粉消化率等方面的作用。这篇综述强调了具有通道结构的淀粉的重要多功能应用。
