Technical Abstract: Pulsed electric field (PEF) nonthermal food processing has been of growing interest owing to its excellent potential to provide consumers with microbiologically-safe and fresh-like quality foods. Application of high voltage electric field at a certain level for a very short time by PEF not only inhibits pathogenic and spoilage microorganisms, but also results in the retention of flavor, aroma, nutrients, and color of foods. This paper provides most current information about PEF food processing. It reviews the systems for PEF processing and its effects on the inhibitions of microorganisms and enzymes and sensory and nutritional properties of foods. Regulatory issues of PEF processing are discussed as well.
