- ... This study investigated the Pulsed Electric field (PEF) effect on apple mash, regarding quantitative, qualitative and sensory attributes, on an industrial scale. PEF treatment (E = 650 V/cm, tPEF = 23.2 ms, q = 32 kJ/kg) was applied to apple mash at the flow rate of 4400 kg/h in a module of colinear design made of four treatment chambers. Juice yield significantly increased from 71.1% to 76.3% due ...

- ... Pulsed electric field (PEF) treatment (E=1000V/cm, f=200Hz and tₚ=100μs) was applied to French cider apple mash pumped into a collinear treatment chamber at the flow rate of 280kg/h. Juices were recovered continuously using a single belt press. PEF treatment of the mash (32ms and 46kJ/kg) increased the juice yield by 4.1%. The content of total native polyphenols decreased by 17.8% in the treated j ...

- ... This study explored the effect of pulsed electric field (PEF) treatment (E = 450 V/cm; tt = 10 ms; E < 3 kJ/kg) and apple mash size on juice yield, polyphenolic compounds, sugars, and malic acid. Juice yield increased significantly after PEF treatment of large mash (Y = 71.4%) and remained higher than the juice yield obtained for a control small mash (45.6%). The acid sweet balance was not altered ...
