Impact of pulsed electric field treatment on the recovery and quality of plant oils

Techniques for extraction of bioactive compounds from plant materials: A review

“…Guderjan et al (2005) showed that the recovery of phytosterols from maize increased by 32.4% and isoflavonoids (genistein and daidzein) from soybeans increased by 20-21% when PEF was used as pretreatment process. Corralesa et al (2008) extracted bioactive compound such as anthocyanins from grape by-product using various techniques and found better extraction of anthocyanin monoglucosides by PEF.…”

Effect of pulsed electrical fields on the structural properties that affect french fry texture during processing

“…It is generally agreed that if the amplitude and duration of the treatment is not too high, the membrane returns from the state of high conductance to its initial state (Chernomordik et al, 1987). Under those conditions, the membrane can reseal, the viability of the cell is maintained (Guderjan, Töpfl, Angersbach, & Knorr, 2005), and metabolic activity can be restored (Pereira, Galindo, Vicente, & Dejmek, 2009). This is known as the "reversible electric breakdown' as the conductance of the cell is increased (Weaver, Powell, Mintzer, Sloan, & Ling, 1984).…”

A Review: Microalgae and Their Applications in CO2 Capture and Renewable Energy

“…This technique applies brief pulses of a strong electric field to cells in the range of nanoseconds to microseconds, inducing the non-thermal permeabilization of the cell membrane and improving mass transport across the cell membranes. Permeabilization depends on the field strength and pulse number (Guderjan et al, 2005;Taher et al, 2011). Under sufficient conditions, irreversible damage of the membrane is reached, and the hardness of the cell is lost; thus, PEF can lead to the complete disruption of cells into fragments.…”

“…Under sufficient conditions, irreversible damage of the membrane is reached, and the hardness of the cell is lost; thus, PEF can lead to the complete disruption of cells into fragments. Moreover, PEF requires less time and energy than other applied methods (Guderjan et al, 2005), and its use as a pretreatment for organic solvent extraction requires fewer organic solvents (usually presenting high toxicity) than the conventional organic solvent extraction (Guderjan et al, 2007). Nevertheless, few studies have applied PEF to pretreat microalgae.…”
