高压脉冲电场提取食品中天然产物的研究进展

Development of pulsed electric field on extraction of natural products in food

高压脉冲电场是当今国际上最热门、最先进的杀菌技术之一,它通过改变细胞的渗透性,而引起细胞死亡或加快细胞内溶质的扩散。目前已将PEF的非热加工机理应用于天然产物的提取中。文章介绍PEF在天然产物提取中的作用原理及其影响因素,主要综述其提取作用在食品工业中的应用,为PEF在天然产物提取方面的研究提供参考。

Now the pulsed electric field is one of the most popular and advanced sterilization technologies in the world,which can lead to cell death or accelerate intracellular solute diffusion by changing the cell permeability.Currently the non-thermal processing mechanism of PEF has used in the extraction of natural products.This article described the principle and influence factors of extracting natural products by using PEF technology,and the application of PEF extraction in food industry were mainly discussed,both of which would provide a reference for the research of extracting natural products by PEF technology.
