Polysaccharides are biologically essential macromolecules, widely exist in plants, which are used in food, medicine, bioactives' encapsulation, targeted delivery and other fields. Suitable extraction technology can not only improve the yield, but also regulate the physicochemical, improve the functional property, and is the basis for the research and application of polysaccharide. High pressure (HP) extraction (HPE) induces the breakage of raw material cells and tissues through rapid changes in pressure, increases extraction yield, reduces extraction time, and modifies structure of polysaccharides. However, thus far, literature review on the mechanism of extraction, improved yield and modified structure of HPE polysaccharide is lacking. Therefore, the present work reviews the mechanism of HPE polysaccharide, increasing extraction yield, regulating physicochemical and functional properties, modifying structure and improving activity. This review contributes to a full understanding of the HPE or development of polysaccharide production and modification methods and promotes the application of HP technology in polysaccharide production.
多糖是生物必需的高分子物质，广泛存在于植物中，用于食品、医药、生物活性物质的包封、靶向递送等领域。合适的提取技术不仅可以提高产量，还可以调节物理化学性质，改善功能特性，是多糖研究和应用的基础。高压（HP）提取（HPE）通过压力的快速变化诱导原料细胞和组织破裂，提高提取产率，缩短提取时间，并修饰多糖的结构。然而，到目前为止，关于 HPE 多糖的提取机制、提高产量和修饰结构的文献综述还很缺乏。因此，本工作综述了 HPE 多糖的提取机制、提高提取产率、调节物理化学和功能性质、修饰结构和提高活性。本综述有助于全面了解 HPE 或多糖生产和修饰方法的开发，并促进 HP 技术在多糖生产中的应用。
