Abstract:Electrical and magnetic fields can enhance the preservation performance for fruits and vegetables，effectively extending the shelf life and maintaining the quality. Accordingly，this technology has become a research hotspot in the field of fruit and vegetable preservation. The principles，classification，and application of electric and magnetic fields in fruit and vegetable preservation were reviewed. Particularly，the preservation mechanisms were introduced from the perspectives of changing enzyme activity，transmembrane potential and transport，and ice crystal formation. The application effects were expounded from the perspectives of weakening respiration，reducing nutrient losses，and inhibiting microbial growth. Finally，the problems and challenges faced by this technology were discussed. The review aimed to provide reference for the development and innovation in the field of fruit and vegetable preservation technology.
