Electromembrane process with pulsed electric field
Desalination, 2006Electromembrane process yields can be enhanced by using pulsed electric field. Electrodialysis experiments carried out on brackish water solutions show that the same level of desalination can be reached faster under pulsed field conditions. A model based on the Nernst–Planck equations is developed to explain this behavior.

Processing of carbonated beer by pulsed electric fields
2014 IEEE Industry Application Society Annual Meeting, 2014The microbiological shelf life of carbonated beer can be extended after being processed by pulsed electric fields (PEFs). Being a nonthermal preservation method, the freshlike taste and the original nutritional value are better retained than with conventional thermal pasteurization (TP).

Pulsed Electric Field Processing
2001Doevenspeck’s patent, dating to the 1960s, describes a variety of pulsed electrical field (PEF) equipment and methods ranging from PEF processing of sausage to specific electronic embodiments. PEF development diverged into two different, though related, areas of endeavor: reversible electroporation, or PEF performed under conditions promoting ...

Pulsed Electric Field Processing
2019Despite comprehensive studies that have reported on the impact of pulsed electric fields (PEF) on the safety, nutrition, sensory, and physicochemical properties of vegetables, juices, and red meat, little research has been reported to address the effect of PEF on aquatic resources such as fish and shellfish.

Enzymatic Inactivation by Pulsed Electric Fields
2001High voltage pulsed electric field (PEF) systems have been studied as one of the most promising nonthermal food preservation methods. The comparison of PEF research requires caution in considering different PEF systems that may affect enzyme activity.

Effect of pulse width on Pulse Electric Field food treatment
2011 IEEE Industry Applications Society Annual Meeting, 2011Recent investigations show that pulsed electric field (PEF) treatment is an effective process to inactivate microorganisms in order to pasteurize liquid foods. The pulsed electric fields are produced by high voltage, short duration and fast rise-time pulses applied to a chamber with liquid passing through it.

A high voltage pulse generator for Pulsed Electric Field pasteurization
2010 20th International Conference on Electronics Communications and Computers (CONIELECOMP), 2010This paper describes the design and implementation of a pulse generator for food pasteurization. Such generator generates a high voltage (15 kV) square wave with a frequency in the range from 250 Hz to 30 kHz. The high voltage supplies two electrodes where, between them, the food is placed and then pasteurized.

Critical Electric Field Strengths of Onion Tissues Treated by Pulsed Electric Fields
Journal of Food Science, 2010Abstract: The impact of pulsed electric fields (PEF) on cellular integrity and texture of Ranchero and Sabroso onions ( Allium cepa L.) was investigated. Electrical properties, ion leakage rate, texture, and amount of enzymatically formed pyruvate were measured before and

Pulsed electric field assisted assembly of polyaniline
Nanotechnology, 2012Assembling conducting polyaniline (PANi) on pre-patterned nano-structures by a high rate, commercially viable route offers an opportunity for manufacturing devices with nanoscale features. In this work we report for the first time the use of pulsed electric field to assist electrophoresis for the assembly of conducting polyaniline on gold nanowire ...

Electric aging of polyethylene in pulsed electric field
Digest of Technical Papers. 12th IEEE International Pulsed Power Conference. (Cat. No.99CH36358), 2003It is known that electric aging of polymer insulation in high pulse fields is a very intensive process which produces many problems. The breakdown after many pulse acts may be due to electric field modification because of the space charge storage or structure modification. Both reasons are discussed in this work for the case of pulse duration less than
