I do not know what part of the citrus is your child allergic to….
It is the citric acid, the essential oils in the peel , the naringin,
etc.
That will be a complicated task to determine and you are unlikely to
use your child as a guinea pig for these experiments.
Trying to replace the lemon juice with other acids such as vinegar
(acetic acid) and tartaric acid, lactic acid will result in different
sensory profile.
The nearest substitute for citric with the typical fruity tang is
malic acid. it is Found in apples
How about apple juice and apple concentrate? Is he not allergic to
it.?
Unfortunately there is no such thing as apple rind that provides the
essential oils like citrus. You may have to compensate that by adding
other flavoring agents that is compatible with the cookery items you
are planning to prepare.
