Abstract: The market demand is directly affected by food freshness and the post-harvest spoilage of raw fresh foods, which causes incalculable economic losses and therefore motivates the development of preservation technologies. High voltage electric field (HVEF) is a safe and environment-friendly technology for food processing. HVEF is one of the most promising technologies to preserve raw fresh foods that requires very small energy consumption with no heat effect and only a small temperature increase in the processed foods and causes little effect on the quality of the foods themselves. This manuscript outlines the basic principle of HVEF and provides a systematic elucidation of its mechanism for preserving fruits and vegetables, aquatic products and meat products with respect to membrane potential, enzyme activities and microstructure. Furthermore, future research prospects are discussed.
