脉冲电场技术在果蔬保鲜中的应用进展OA

As an innovative physical preservation technology,pulsed electric fields(PEF)exhibits the advantages of short treatment time,low heat generation,low energy consumption,and negligible adverse effects on material quality,thus possessing great application potential in the preservation of fruits and vegetables.The preservation mechanism of pulsed electric field mainly involves two aspects:1)ionization on the surface of fruits and vegetables generates ozone and other active particles,which effectively kills microorganisms;2)activation of internal physiological metabolism in fruits and vegetables regulates endogenous enzyme activity,thereby delaying maturation and aging.This paper systematically reviews the technical characteristics,preservation mechanism,application status,and current challenges of PEF,aiming to provide insights for the advancement of fruit and vegetable preservation technology.
