摘要
微波萃取技术作为一种新型高效的萃取技术,是近年来的研究热门课题。微波可以穿透萃取介质,直接加热物料,能缩短萃取时间和提高萃取效率。本文对近年的微波萃取技术以及其研究做了综述,介绍了微波萃取的特点、主要影响因素及其应用。
Microwave assisted extraction has attracted growing interest as it allows rapid extractions of solutes from solid matrices in recent years,with high extraction efficiency comparable to that of the classical techniques. Microwave assisted extraction consists of heating the extractant in contact with the sample with microwave energy. But unlike classical heating,microwaves heat all the sample simultaneously without heating the vessel. Therefore, the solution reaches its boiling point very rapidly, leading to very short extraction times. This review gives a brief presentation of the theory of microwave and extraction systems,a discussion of the main parameters that influence the extraction efficiency,and the main results on the applications.
