Silica is great for removing humidity from air. But what I want is to remove oxygen from air, so my food stays fresh longer. Any clean and easy to use substance/method for that purpose?

Oxygen absorbers. Little paper packets of iron powder.

I think a lot of us might even confuse the two. The packets look fairly similar too.
