蒸汽爆破辅助中药提取技术研究进展OA

The steam explosion-assisted extraction technology can penetrate plant tissues by high-temperature and high-pressure steam and destroys the connection structure of cellulose,hemicellulose and lignin in the cell wall,forming porous channels and thereby promoting the dissolution of active components of traditional Chinese medicine through instantaneous pressure release that internal energy is converted into mechanical energy.Its core advantages include high extraction efficiency,environmental friendliness without chemical residues,effective conversion of some traditional Chinese medicine active components,and strong process adaptability enabling"one explosion for multiple extractions".The effect of steam explosion is closely related to the properties of traditional Chinese medicine materials:it is suitable for fiber-rich traditional Chinese medicine with dense cell walls,such as fungal,rhizome,woody/pericarp,and leafy varieties,but not suitable for high-moisture or extremely heat-sensitive materials.As a pretreatment technology,steam explosion can produce synergistic effects when combined with techniques like ultrasonic extraction,hot water extraction,and response surface methodology,further improving extraction efficiency and protecting active components,thus providing diversified pathways for industrial application.Currently,the technology still faces challenges such as insufficient standardization of process parameters for different traditional Chinese medicine,lagging development of industrial equipment,and inadequate in-depth basic research.In the future,by further strengthening basic research and making breakthroughs in research directions including process standardization,equipment intelligence,and application scenario expansion,steam explosion technology is expected to become one of the core supporting technologies driving the green,efficient,and large-scale development of the traditional Chinese medicine industry.It will promote the transformation of the traditional Chinese medicine industry from extensive processing to precision manufacturing,facilitating the modernization and internationalization of traditional Chinese medicine.
