the food industry is interested in innovative non-thermal processing technologies such as pulsed electric field (pef), ultrasound (us), high hydrostatic pressure, ultraviolet radiation, due to their ability to preserve the food quality, minimize nutrient loss during processing, and efficient energy use as compared to conventional thermal …
PEF processing involves the application of short pulses (µs) of electric fields intensity (E) varying from 0.1 to 40 kV/cm, depending on the pursued objective.As seen in Fig. 1, the increase of product shelf-life by the inactivation of microorganisms and enzymes is usually achieved with HIPEF (20-40 kV/cm).On the other hand, MIPEF (1-20 kV/cm) is commonly applied as pretreatments for the
food security including safety and quality issue in the modern food supply chain. The agricultural and food processing applications of pulsed power technologies such as intense pulsed electric eld and time-modulated discharge plasmas have been studied and growing rapidly in researchers worldwide (Takaki et al. 2019). The
The Basic Principles. Pulsed Electric Field processing is nonthermal and allows the targeted permeabilization of biological cell membranes. This effect, termed electroporation, results in release of intracellular substances and cell death. Pore formation occurs when, by an external electrical field, a transmembrane potential of approximately 1

[9-12], and high-intensity pulsed electric field (PEF) application [13-15]. Ohmic heating is one of the ear-liest forms of electricity applied to food pasteurization [1]. This method relies on the heat generated in food products when an electric current is passed through them. Getchell [2] described the ohmic heating method in milk
Food Science and Technology, 2015 Fyffe Road, Columbus, OH 43210-1007 Pulsed Electric Field Processing Fact Sheet for Food Processors Raghupathy Ramaswamy, Graduate Research Associate Tony Jin, Ph.D., PEF Pilot Plant Manager V. M. (Bala) Balasubramaniam, Ph.D., Assistant Professor, Food Safety Engineering
The ever-increasing trend toward nutritionally qualified foods has challenged food technology to produce fresh-like foods by replacing thermal treatments with alternative methods of preservation. Thermal processing is a major technology that has been commonly used in
High-intensity pulsed electric field (PEF) processing involves the application of pulses of high voltages (typically 20-80 kV cm −1) of exponentially decaying, square wave, bipolar, or oscillatory pulses and at ambient, subambient, or slightly above ambient temperatures for less than 1 s to foods. High-intensity electric fields applied to a
transfer of PEF processing technology from lab scale into industrial food processing. The Basic Principles Pulsed Electric Field processing is nonther – mal and allows the targeted permeabilization of biological cell membranes. This effect, termed electroporation, results in release of intracellular substances and cell death. Pore Pulsed electric field (PEF) processing is a non-thermal method of food preservation that uses short bursts of electricity for microbial inactivation and causes minimal or no detrimental effect on food quality attributes. PEF can be used for processing liquid and semi-liquid food products.
1. Introduction. Pulsed electric field (PEF) treatment is a nonthermal food processing method as the rise in temperature is small during application in most cases. PEF treatment has potential as a minimal processing method ( Morales-de la Peña, Rábago-Panduro, Soliva-Fortuny, Martín-Belloso & Welti-Chanes, 2021 ).
