SalivarY Amylase

Why does the digestion of starch cease in the stomach?

I know that salivary amylase, which breaks starch down, has a pH optimum at 7...

So if the optimum pH for the enzyme is 7, and stomach pH is around 2.3, why does salivary amylase stop acting in the stomach?

But keep in mind, Further carb digestion occurs in the small intestine where the pancreas releases amylase.
