“…PEF has been used in deactivation of microorganisms in milk, dairy products, egg, water, and other food materials (Qin, Chang, Barbosa-Cfinovas, & Swanson, 1995). Sarkis et al (2015) used the PEF and high voltage electrical discharge as the pretreatment in oil extraction from sesame seeds with the purpose of destructing the cell wall and increasing the oil extraction efficiency. Their results indicated that when the output energy of high voltage process increases, the destruction index might increase and also these two procedures lead to an increase in oil extraction efficiency.…”

Application of novel technologies such as microwave and pulsed electric fields (PEF) might increase the speed and efficiency of oil extraction. In the present research, PEF (3.25 kV/cm electric field intensity and 30 pulse number) and microwave (540 W for 180 s) pretreatments were used to study the process of oil extraction from black cumin (Nigella sativa) seeds. After applying the selected pretreatments, the oil of seeds was extracted with the use of a screw press and the extraction efficiency, refractive index, oil density, color index, oxidative stability, and chemical components of oil and protein of meal were evaluated. The achieved results expressed that PEF and microwave pretreatments increased the oil extraction efficiency and its oxidative stability. Different pretreatments didn't have any significant influence on the refractive index of black cumin seed oil (p>.05). When microwave and PEF were used, the oil density showed an enhancement as the following: 1.51% and 0.96%, respectively in comparison with the samples with no pretreatments. Evaluation of the extracted oils, using GC/MS analysis indicated that thymoquinone was the dominant phenolic component in the black cumin oil. Finally, the SEM analysis revealed that microwave and PEF can be useful in the extraction of oil from black cumin seeds since these treatments damaged cell walls and facilitated the oil extraction process.

“…Crucially, it was found that the extracts from rapeseed cake had a significant increase in their antioxidant activity following HVED treatments. Other studies have shown the efficacy of this technique to extract phenolics from different oilseed sources, including sesame cake and flaxseed cake (Boussetta et al, 2013;Sarkis et al, 2015). The study by Barba et al was an initial optimisation, in addition to being the first step in the search for more efficient methods to isolate phenolic compounds from rapeseed by-products.…”

Rapeseed is one of the world’s major oilseeds, and rapeseed oil is produced by pressing of the seeds. This process results in the production of a low-economic-value by-product, rapeseed meal, which is commonly used as animal feed. Rapeseed meal is rich in bioactive phenolic compounds, including sinapinic acid (SA) and protocatechuic acid (PCA). Isolation of these bioactive compounds from a by-product of rapeseed oil production is largely in agreement with the current concept of the circular economy and total utilisation of crop harvest using a biorefinery approach. In this review, current information concerning traditional and novel methods to isolate phenolic compounds – including SA and PCA – from rapeseed meal, along with in vitro and in vivo studies concerning the bioactivity of SA and PCA and their associated health effects, is collated. These health effects include anti-inflammatory, anti-cancer, anti-diabetes activities, along with histone deacetylase inhibition and protective cardiovascular, neurological and hepatic effects. The traditional extraction methods include use of solvents and/or enzymes. However, a need for simpler, more efficient methodologies has led to the development of novel extraction processes, including microwave-assisted, ultrasound-assisted, pulsed electric field and high-voltage electrical discharge extraction processes.

“…Авторы [7,13] отмечают увеличение выхода масла с использованием предварительной обработки ИЭП зародышей кукурузы и оливок на 32,4 и 7,4% соответственно. В качестве предварительной обработки семян кунжута перед экстракцией авторы [12] использовали обработку ИЭП и высоковольтный электрический разряд, что позволило увеличить выход масла на 4,9 и 22,4% соответственно. Полученные ими данные показали, что для более эффективного извлечения масла необходимо увеличение индекса разрушенных клеток, что в свою очередь зависит от величины затрачиваемой энергии.…”

The prospects of pulsed electric field (PEF) application for the extraction processes of oily materials is dealt with, main quality parameters of the oil being analyzed. Evaluation of PEF treatment efficiency for extraction process of sunflower cake was carried out upon the following criteria: oil yield, index of disintegrated (destroyed) cells, diffusion coefficient. In addition the main quality parameters of extracted oil after treatment were determined by standard methods. It was found that PEF processing at the preliminary stage allowed to increase the yield of oil up to 3.5%, while the diffusion coefficient increased from D = 9.8943E-12 to 1.5504E-11 m 2 /s. The number of pre-opened cells increased by 42.9% after treatment by PEF. PEF was shown to have a slight effect on oil quality parameters (P>0.05), that is primarily due to the nature of the applied pulses and, as a consequence, to the absence of heating in the treatment zone. The results obtained can be used for upscaling technology of electro physical processing by pulsed electric field treatment for the intensification of mass transfer processes.Keywords: pulsed electric field; mass-exchange processes; extraction kinetics; diffusion coefficient; disintegration index; sunflower. ВведениеОсновным промышленным методом получения подсолнечного масла в маслоэкстракционном производстве на сегодняшний день является твердо-жидкая экстракция с применением способов противоточного погружения и многоступенчатого противоточного орошения [1]. Существует множество разнообразных методов и способов интенсификации процесса экстрагирования как на стадии подготовки материала, так и при непосредственном воздействии в самом процессе экстрагирования. К таким методам можно отнести СВЧ обработку, сверхкритическую СО2 экстракцию, обработку с использованием ультразвука и электроразрядную обработку в жидкости [2][3][4][5].
