Can alum be used in cooking?

Alum can cause stomach problems although it was once used in the pickling process to make pickles crisper.
Alum is used in the canning process, particularly for pickles, to provide extra crunch. It is allowed by government agency, but its use is not recommended. Do not use in final product, only in intermediate soaking steps.
