“…PEF has been applied to improve release of intracellular compounds from plant tissue with the help of increasing cell membrane permeability (Toepfl et al, 2006). PEF treatment at a moderate electric field (500 and 1000 V/cm; for 10 À4 -10 À2 s) is found to damage cell membrane of plant tissue with little temperature increase (Fincan and Dejmek, 2002;Lebovka et al, 2002).…”

“…Non-conventional methods, which are more environmental friendly due to decreased use of synthetic and organic chemicals, reduced operational time, and better yield and quality of extract, have been developed during the last 50 years. To enhance overall yield and selectivity of bioactive components from plant materials, ultrasound (Vinatoru et al, 1997;Ghafoor et al, 2011), pulsed electric field (Toepfl et al, 2006), enzyme digestion (Gaur et al, 2007), extrusion (Lusas and Watkins, 1988), microwave heating (Kaufmann and Christen, 2002), ohmic heating (Lakkakula et al, 2004), supercritical fluids (Marr and Gamse, 2000;Lang and Wai, 2001;Meireles and Angela, 2003;Wang et al, 2008;Ghafoor et al, 2010Ghafoor et al, , 2012, and accelerated solvents (Kaufmann and Christen, 2002;Smith, 2002) have been studied as non-conventional methods. At the same time conventional extraction methods, such as Soxhlet is still considered as one of the reference method to compare success of newly developed methodology.…”

“…Siempre que el proceso este´optimizado, se considera que los PEAV permiten ahorrar energı´a respecto a los tratamientos te´rmicos convencionales (Toepfl, Mathys, et al, 2006). Por ejemplo, se ha calculado que la energı´a especı´fica necesaria para la pasteurizacio´n de la leche mediante PEAV se situ´a entre los 110 y los 200 kJ/L, lejos de los alrededor de 300 kJ/L necesarios para la pasteurizacio´n HTST (SobrinoLo´pez & Martı´n-Belloso, 2010).…”

Es cierto que estos 300 kJ/L pueden reducirse hasta en un 80-95% gracias a los procesos de recuperacio´n de energı´a, pero tambie´n lo es que en el caso de los PEAV combinados con temperaturas moderadas se podrı´an utilizar equipos de recuperacio´n similares (Toepfl Mathys, et al, 2006). Asimismo, dado que la temperatura a utilizar serı´a inferior (alrededor de 608C), tambie´n podrı´a producirse un ahorro energe´tico indirecto, al requerir menos energı´a de enfriamiento que en la pasteurizacio´n HTST.…”
