A Brief History Of Pulsed Electric Fields Pef Use In Potato Industry A brief history of pulsed electric fields (pef) use in potato industry | elea. in the potato industry, pef has become an industry standard in recent years. the technology´s use leads to cell electroporation and reduced turgor pressure, a significant tissue softening occurs. that facilitates cutting of fruit and vegetable tissue and allows to. Angersbach suggested the use of pef to accelerate drying of potato cubes as well as to improve starch extraction. 1997 to 1998 a nationally funded research project was conducted in a cooperation.

A Brief History Of Pulsed Electric Fields Pef Use In Potato Industry The first pulsed electric field (pef) system was installed in the potato processing industry in 2010. nowadays, over 100 machines are in use in the industry, most of them for french fries and potato chips (elea gmbh 2020 ). in the past, a preheater was applied to soften the raw potato making it processable for french fry production. Introduction. the practical applications of the continuous (dc) or alternating (ac) electric currents for heating of foods and for killing of microbes in liquid foods were started about one hundred years ago. in the middle of twentieth century the pulsed electric field (pef) processing of foods was launched. Pulsed electric field (pef) technology is a non thermal approach mainly used to preserve food with higher electrical conductivity, such as liquid or semi liquid foods. pef uses an electric field to create irreversible poration in the cell membrane, increasing membrane permeability. In this paper, a short analysis of the potato structure and its nutritional properties, applications of moderate electric fields, ohmic heating, and pulsed electric fields are presented. moreover.

Advancing Pef Technology To The Potato Chip Industry вђ Be Profy In Pulsed electric field (pef) technology is a non thermal approach mainly used to preserve food with higher electrical conductivity, such as liquid or semi liquid foods. pef uses an electric field to create irreversible poration in the cell membrane, increasing membrane permeability. In this paper, a short analysis of the potato structure and its nutritional properties, applications of moderate electric fields, ohmic heating, and pulsed electric fields are presented. moreover. Compared to thermal extraction non thermal technologies such as pulsed electric field (pef) support using efficient and easy identification, categorization, and analysis of bioactive components. other advantages of pef include cost efficacy, less time, and solvent utilization with enhanced yields. July 10, 2018. source. elea gmbh. a study on the impact of pulsed electric field treatment (pef) in the potato processing industry has shown substantial benefits in comparison to the regular process using conventional pre heaters. in particular the effect on the environmental impact sustainability of the process is substantial.
