Supercritical CO2UltrasoundContinuous regimeSacharomyces cerevisiae inactivation[EN] Laboratory continuous regime equipment was designed and built for supercritical CO2 microbial inactivation assisted by high power ultrasound (SC-CO2-HPU). Apple juice, previously inoculated with 1-10x107 CFU/ml of Saccharomyces cerevisiae, was treated in the equipment at different juice residence times (3.06-9.2 min), temperatures (31-41 °C) and pressures (100-300 bars). Inactivation ratios were fitted to a hybrid (boolean-real) model in order to study the effect of the process variables. The maximum inactivation achieved by the system was 7.8 log-cycles. The hybrid model demonstrated that HPU has a significant effect on inactivation after shorter residence times. A multi-objective optimization performed with the hybrid model showed that 6.8 log cycles of inactivation could be obtained after a minimum residence time (3.1 min) with HPU application, whereas under the same conditions but without HPU, the inactivation would be 4.3 log-cycles. Therefore, the ultrasound assisted continuous system has shown a great potential for microbial inactivation using SC-CO2 under mild process conditions.Reserva de todos los derechosAbiertohttp://hdl.handle.net/10251/106859Elsevierapplication/pdf Antonio Mulet Pons M.A. García-Alvarado José Javier Benedito FortJournal of Food EngineeringInglés
