Like this:
== Starch Gelatinization
{title2=Boiling of food}
It shows up as
Starch Gelatinization (Boiling of food)
on the page (but not on indexes/ToC, that could be considered but needs thought), but keeps the ID shorter to just /pioyi/starch/starch-gelatinization
rather than /pioyi/starch/starch-gelatinization-boiling-of-food
which is what you might want.
