Alcohol, aldehyde, and ketone are also important to the flavor of
fermented milk. Comparing the alcohol and ketone contents in the
two fermented milk samples, there were more of these compounds
in the fermented sample with 60 g/kg of onion juice added, but the
aldehyde content was the opposite: more was found in the control
sample. Aldehyde is labile and has a high level of activity.When the
fermented milk was supplemented with onion juice having
considerable antioxidant substances, part of the aldehyde might
have been reduced to alcohol or other compounds. Overall, adding
onion juice into milk increased the volatile compounds in fermented
milk and changed their flavor compounds profile.
