The pasteurization of fresh or previously frozen peach induced
an increase in chlorogenic acid and zeaxanthin while for
becryptoxanthin and becarotene their content decreased. Storage
for 360 d at 20 C induced an increase on (þ)-catechin and zexanthin
while the remaining phenolics and carotenoids decreased.
Pasteurization after 360 d frozen peach induced a decrease on
neochlorogenic acid, chlorogenic acid and quercetin-3-rutinoside
between days 230 and 360. In carotenoids the lutein strongly
decreased and zeaxanthin content increased after pasteurization of
samples stored for 60 d. The remaining carotenoids presented no
significant differences between samples pasteurized and
unpasteurized.
