“…After a certain diffusion time, we can see that samples treated by PEF and HVED reach very similar concentration values, whereas control presents smaller concentrations even after 60 min. A similar behavior was observed by Moubarik et al (2011) that compared extraction kinetic using ultrasound, PEF and HVED. When comparing the treatments applied it is possible to observe, in Fig.…”

“…This variation of the electrical disintegration index with PEF energy input was also observed by Loginova et al (2011) for beets. The effect of these treatments on the increase of solutes concentration in the medium were observed by Loginova, Shynkaryk, Lebovka, and Vorobiev (2010) in PEF treatment of chicory and by Moubarik, El-Belghiti, and Vorobiev (2011) in HVED treatment of fennel. showed that the number of discharges increased the extraction efficiency of polyphenols up to a treatment time of 8 ms, which corroborates what was observed in this work.…”

“…2 and 4. Moubarik et al (2011) calculated the kinetic coefficients of solute diffusion in water after different PEF, ultrasound and HVED treatments and concluded that the most rapid kinetics was obtained with discharges and the slowest with ultrasound. The comparison between solvents was not significant for the electrically treated cakes and, for the control, only 50% was significantly worse than other solvents.…”

Summary A pilot study for the pulsed electric fields (PEF) assisted countercurrent diffusion of inulin from chicory roots is presented. The influence of PEF parameters (electric field intensity E = 600 V cm−1, treatment duration tPEF = 10–50 ms) and diffusion temperature (varied between 30 and 80 °C) on soluble matter extraction kinetics, inulin content of juice, and pulp exhaustion are investigated. The draft (liquid to solid mass ratio) was fixed at 140%, similar to the industrial conditions. PEF treatment facilitates extraction of inulin at conventional diffusion temperature (70–80 °C), and diffusion temperature can even be reduced by 10–15 °C with comparable juice inulin concentration. Less energy consumption can be achieved by reducing PEF treatment duration to 10 ms, which is observed sufficient for effective extraction.

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].
