Different letters in each column indicate significant differences at , according to a LSD test. OD: osmotic dehydration at atmospheric pressure; PVOD: pulsed vacuum, both with conventional heating; OH: ohmic heating (OD/OH and PVOD/OH), electric field intensity at 6.66 V/cm (50 V) (processing time = 180 min).
