Abstract :This study aimed to test a pilot-scale continuous ultrasonication insert ignore into journalissuearticles values(US); system to pasteurize whole milk in terms of physical properties, energy consumption, and inactivation of alkaline phosphatase insert ignore into journalissuearticles values(ALP);, total mesophilic aerobic bacteria insert ignore into journalissuearticles values(TMAB);, total coliform insert ignore into journalissuearticles values(TC);, total enterobactericeae insert ignore into journalissuearticles values(TE);, and Escherichia coli. Except for those treated by 90% amplitude for 20 and 30 min, the samples were found negative for ALP activity. Inactivation of TC, TMAB, TE, and E. coli rose with an increased amplitude and temperature. The maximum cost was estimated at 2.778,00 € for the system and at 3.624,00 € for plate heat exchanger to pasteurize 20.000 L of milk. 96.52% amplitude, 40 min, and 53.50 °C were determined jointly as the optimal operational settings.Keywords : Ultrasonication, Milk processing, Optimization, Alkaline phosphatase, Cost analyses
