Pulsed Electric Field Processing of Milk
2021Pulsed electric field (PEF) is a powerful high electric field pulse with a short pulse width (in micro- or nanoseconds) and is identified as one of the effective non-thermal treatment processes for decontamination and inactivation of microorganisms with minimal heat production for a wide range of applications.

Food Science and Technology International, 2008
The concept of pulsed electric fields (PEF) was first proposed in 1967 to change the behavior or microorganisms. The electric field phenomenon was identified as membrane rupture theory in the 1980s. Increasing the membrane permeability led to the application of PEF assisted extraction of cellular content and transfer of genetic material across cell ...

Applications of Pulsed Electric Fields in Winemaking
2022Wineries may take advantage of the ability of PEF to electroporate cell membrane of grape skins and microbial cells to improve different operations. PEF permeabilization of red grape skin cells permits reducing the duration of the maceration or to increase the color and concentration of anthocyanins and polyphenolic compounds in the wine without ...

Dichroism of TMV in pulsed electric fields
Biopolymers, 1971AbstractThe linear dichroism induced in a solution of electrically anisotropic molecules by a pulsed electric field has been studied. Equations have been obtained which express the dichroism as a function of dipole moment, excess polarizability, field strength, and the angle α between the dipole moment and the transition moment for the absorption band.

Killing of microorganisms by pulsed electric fields
Applied Microbiology and Biotechnology, 1996Lethal effects of pulsed electric fields (PEF) on suspensions of various bacteria, yeast, and spores in buffer solutions and liquid foodstuffs were examined. Living-cell counts of vegetative cell types were reduced by PEF treatment by up to more than four orders of magnitude (> 99.99%).

Rhabdomyolysis Due to Pulsed Electric Fields
Plastic and Reconstructive Surgery, 1990High-voltage electrical trauma frequently results in extensive and scattered destruction of skeletal muscle along the current path. The damage is commonly believed to be mediated by heating. Recent experimental and theoretical evidence suggests, however, that the rhabdomyolysis and secondary myoglobin release that occur also can result from ...

Impact of Pulsed Electric Fields on Enzymes
2016Pulsed electric field (PEF) processing has emerged as a promising technology in the development of tailor-made processes to effectively control the enzyme activity. It has been proven as an effective technique for the preservation of food products as it can result in substantial inactivation of most undesirable enzymes.
