resulted in the highest inactivation of enzymes and microbial cells
with lower losses of ascorbic acid, total phenolics, flavonoids and
flavonols. Although, further research would be necessary to optimize
the conditions by evaluating different extrinsic parameters
but under these conditions the application of ultrasound withprobe
at 60 C was found to be an appropriate treatment. The data
may reflect the application of ultrasound treatments to produce
good quality apple juice with reduced enzymes and microbial
activities and improved retention of other bioactive compounds
