汽爆技术促进中药资源高值化利用

汽爆技术在中药资源高值化利用中发挥的作用正在逐渐体现:汽爆处理打破中药植物细胞壁的屏障结构,有利于有效成分的分离提取;汽爆过程物料自体水解发生去糖苷化作用使天然植物中的苷元与糖基分离,提高苷类物质提取和分离效率;汽爆应用于中药炮制和中药脱毒有高效、快速和避免有效成分流失等优点;汽爆处理有利于中药非药用组分如纤维素、半纤维素等的有效分离和利用,联产乙醇、丁醇等能源和化工产品。本文对汽爆技术在中药资源高值化利用中的研究进展进行了综述。

Steam Explosion Technology Applied to High-Value Utilization of Herb Medicine Resources

Utilization of herb medicine requires combination of modern and traditional methods to develop new medicines which are high quality,safe,stable and convenient.At the same time,herb medicine resource is an important biomass resources,can be used to replace petroleum,gas and coal resources for energy,materials and chemicals production.Application of modern technology to enhance the value of the herb medicine resources is an important development direction for herb medicine research.The roles of steam explosion technology for high-value utilization of herb medicine resources are gradually exhibiting: steam explosion treatment can break the barriers of herb medicine plant cell wall structure,as a result,it is conducive to separation and extraction of active ingredients from medicine plant;steam explosion is contributed to the deglycosylation of glycosides in the natural plants and improves the efficiency of extraction and separation of aglycone;steam explosion is used in herb medicine processing and detoxification with several advantages such as efficient,fast,avoiding the loss of active ingredients,etc;steam explosion process is conducive to effective separation and utilization of non-medicinal components such as cellulose and hemicellulose for the production of ethanol,butanol and other energy and chemical products.This paper reviews the research of steam explosion technology for the high-value utilization of herb medicine resources.
