摘　　要：低温等离子体在处理过程中能够产生羟自由基、过氧羟自由基、超氧阴离子自由基、氧负离子自由基等化学活性物质,对有机物质的改性降解有独特的效果。本文简要介绍了低温等离子体的产生方式及其性能,综述了低温等离子体技术在生物聚合物中的应用研究进展,归纳总结了低温等离子体对多糖、蛋白质及其他多聚物的降解改性机理。Non-thermal plasma is able to induce the production of highly active species such as hydroxyl radical （OH·）, hydroperoxyl radical （HO2？）, superoxide anion radical （O2-·）, and atomic oxygen radical anion （O-）, and it has a distinctive effect on degrading and modifying biopolymers. The generation and properties of low temperature plasma are described in this review. This article also reviews recent progress in the application of low temperature plasma in the degradation and modification of biopolymers. In addition, the mechanisms of degradation and modification of polysaccharides, proteins and other polymers by low temperature plasma are also summarized.
