Reply To: Mozzarella cheese doesn't need hashgacha?

apushatayid: Yes, I obviously meant that gluten content gives something the ability to become Chametz if it is left to leaven. A bunch of Rabbanim in Eretz Yisrael hold that way (I think I heard that R’ Zalman Nechemya Goldberg does) and I think Kehati mentions it in the beginning of Challah and quotes a chunk of Rabbanim who said it.
