This study investigated the Pulsed Electric
fi
eld (PEF) effect on apple mash, regarding quantitative,
qualitative and sensory attributes, on an industrial scale. PEF treatment (

32 kJ/kg) was applied to apple mash at the
fl
ow rate of 4400 kg/h in a module of colinear design
made of four treatment chambers.
Juice yield signi
fi
cantly increased from 71.1% to 76.3% due to PEF treatment. A signi
fi
cant increase of
8.8% was also observed for the native polyphenols concentration when an inhibitor of the enzymatic
oxidation was added. Juice colour was signi
fi
cantly altered by the PEF treatment. The saturation in the
yellow rose signi
fi
cantly from 17.9 to 26.8.The juice from treated mash was less turbid and was described
by odour intensity and typical odour of apple signi
fi
cantly higher than the untreated sample. Similarly,
the overall and typical taste of apple juice were signi
fi
cantly more intense. The chemical composition
(Fructose, Glucose and Malic acid) of juice did not vary despite a signi
fi
cant increase of the dry matter for
treated samples. On the contrary, a signi
fi
cant depletion of fructose and glucose was noted for the
pomace from treated mash as compared to the control.
