it was found that apple juice had the lowest protectiveeffect on AA in fortified fruit juices comparing to orange and blackcurrant
juices. Apple juice phenolic acids were recognised as less
efficient protectors of AA than flavonoids of orange and blackcurrant
juices (Miller & Rice-Evans, 1997). These results may explain
higher losses of AA in apple juices than in multifruit juices analysed
in the present study. It was observed that oxidation process
was only partly responsible for the loss of AA because the concentration
of DHAA did not compensated the decrease of AA in fresh
juice
