For the ohmic heating treatments, the pulp temperature was raised applying the voltage determined by the experimental design until a temperature of 90 °C was reached. The voltage was then lowered to maintain the pulp at this temperature for 2 min. This time/temperature condition was chosen because it is suggested in literature to inactivate anthocyanin-degrading enzymes (Fennema, 2010). When the thermal treatment was complete, the product was rapidly cooled by passing cold water (4 °C) through the jacket.
