“…The product between two electrodes is subjected to brief electrical pulses from a few nanoseconds to milliseconds at high voltage (between 100 and 300 V/cm and 80 kV/cm). Due to the highintensity electric field pulse discharges caused by PEF treatment, cell membrane characteristics can change, increasing cell membrane permeability and accelerating cytoplasmic disintegration [37].…”

Nature has given us a wide range of biological compounds that can be utilized to help combat health problems, but sometimes with over-processing, these advantages are diminished or lost. Food and pharmaceutical companies have developed a range of new approaches to harness and retain the naturally occurring diversity and quality of bioactive compounds efficiently and effectively. Pharmaceutically important plant products have been known for millennia; they have been used in crude and unrefined forms. One of the best ways to pick the best plant bioactive is through genetic engineering, omics, and plant tissue culture. Many laboratories routinely screen plant species for bioactive compounds to discover new ones. All extraction methods depend on the researcher's preference and what exactly the research entails. Successful extraction begins with the careful selection and preparation of plant samples and thorough knowledge and review of the appropriate literature. Here we have attempted to describe the different stages and methods of extraction from the medicinal plants. From the review, it can be concluded that no universal extraction method is ideal and that each extraction procedure is unique.

“…Several studies have been published on the disintegration of cell membranes in plant tissues by the application of PEF [ 14 , 15 , 16 , 17 ]. In particular, Devkota et al [ 14 ] studied the phenomena on common beans, while Naliyadhara et al [ 15 ] highlighted the importance of PEF treatment for the extraction of various compounds from the food matrix such as juices, edible oils, bioactive compounds and carbohydrates and how the cell membrane mechanism is involved in these outcomes. Shorstkii et al [ 16 ] found more increased porous volume parameters of the cells in sunflower oil pilot production.…”

The aim of this study was to investigate how the treatment of olive paste of the Picholine variety with pulsed electric fields (PEF) under real operating conditions in a large-scale olive oil extraction plant affects the extractability, chemical composition and sensory profile of the oils. The application of pulsed electric fields (PEF) as a non-thermal food processing technology is interesting for many food extraction processes. The results of this study show that pulsed electric fields can be used as a pretreatment before oil separation to increase the extractability of the process and improve the content of functional components. The application of pulsed electric field (PEF) treatment (2.4 kV/cm, 4 kJ/kg, 6 µs pulse width) to olive paste through a continuous system significantly increased the extractability and total concentration of phenols (especially oleuropein derivatives) compared to the control. In addition, the volatile compounds, α-tocopherol, the fatty acid profile and the main legal quality parameters of extra virgin olive oil (EVOO), including free acidity, peroxide values, extinction indices and sensory analysis, were evaluated. The pulsed electric fields (PEF) treatment did not modify these EVOO quality parameters, neither the α-tocopherol content nor the volatile profile. The sensory properties of EVOO were not affected as well as the PEF treatment showed a similar intensity of fruity and pungent attributes without any off-flavor according to the European Union legal standards. An increase in the bitter taste attribute was observed in the PEF oils. Consequently, this study demonstrates that pulsed electric fields (PEF) processing could be implemented in olive oil processing as pretreatment for improving the efficiency of the process.

“…Compared with electromagnetic microwave radiation, the use of PEF is a novel method-the beneficial impact of which on biogas output has not been given much attention in the literature. The available reports deal with structural changes in the cell wall and membrane in plants, which directly increase the cell membrane permeability and, in consequence, accelerate and intensify the sugar hydrolysis process [14][15][16][17].…”

Cross-Comparison of the Impact of Grass Silage Pulsed Electric Field and Microwave-Induced Disintegration on Biogas Production Efficiency

Lignocellulosic biomass is included in the group of renewable energy sources. Its calorific value is high, owing to which it can be successfully used in the production of second-generation fuels, e.g., biogas. However, its complex structure makes it necessary to apply a pretreatment in order to increase the biogas output. This study presents the usability of a pulsed electric field in grass silage pretreatment in methane fermentation and compares it with microwave-induced disintegration. The experiment shows that substrate disintegration with a pulsed electric field (PEF) results in an increase in methane output. The productivity of methane from PEF pretreatment silage increased by 20.1% compared to the untreated control. The application of microwave disintegration, with the assumption that the same energy is used for the pretreatment, resulted in a methane output increase of 6% compared to the control. The highest biogas production output in PEF-pretreated samples was 535.57 NL/kg VS, while the highest biogas output from substrates pretreated with microwaves was 487.18 NL/kg VS.
