observed the retention of ascorbic acid in
strawberry juice treated with ultrasound (20 kHz using a 1500 W
ultrasonic processor). This result was attributed to the elimination
of dissolved oxygen during cavitations, which is essential for
ascorbic degradations.
Ascorbic acid retention reduced colour change during storage,
which is appropriate because colour is associated with the selection
of fresh vegetables. The stability of vitamins is different from food
to food, even when they are subjected to similar processing and
storage.
