Abstract
The impact of two types of electrical treatment, electro-osmotic (EO) and moderate electric field pulses (MEFP), on intensifying juice pressing from apple cossettes has been studied. The experiments were carried out in a laboratory filter-press cell fitted with the appropriate electrical treatment system. Both EO and MEFP treatments result in a significant intensification of juice yield. Energy consumption, however, is 50–100 times less for MEFP treatment. Since a significant appearance of electrolytic processes and ohmic heating is observed with EO treatment, this treatment is very limited. MEFP treatment does not have these drawbacks and reduces the juice coloration. © 2000 Society of Chemical Industry
