高压脉冲电场技术在果蔬汁加工及贮藏中的研究进展

Advances on application of high voltage pulsed electric field in fruit and vegetable juice processing and storage

高压脉冲电场(HPEF)技术是近年来国际上热门的非热加工技术之一,不仅具有好的杀菌、钝酶效果,耗能较低,而且可较大程度地保持原料原有的营养物质和感官特性。近年来,HPEF技术在液态食品加工领域中的研究取得了一定进展,特别是在果蔬汁领域中。文章介绍了HPEF技术的原理以及在果蔬汁加工及贮藏过程中的影响因素和应用途径,并对HPEF技术在果蔬汁行业的应用前景进行了分析和展望。

As one of the most advanced thermal processing technologies in the world, high voltage pulsed electric field （HPEF） technology not only has better effect of sterilization and of blunting enzymes, low energy consumption, but also has good preservation effect for keeping the original sensory and nutritional elements of the raw materials. HPEF shows significant advantages compared to other processing technologies. The application of HPEF technology in liquid food, especially in fruit and vegetable juice industries, has made some progress recently. The mechanisms of HPEF technology, factors influencing its effects during processing and storage of fruit and vegetable juice as well as its possible application have been introduced. Its advanced application in fruit and vegetable juice industries is also prospected.
