in the wet gluten

, referred to as water-binding capacity. … The gluten index is the ratio of the wet gluten remaining on the sieve (after centrifugation) to the total wet gluten.

What's a good substitute for wheat gluten?

Use flour made from rice, potato starch, soy, tapioca, or corn

instead. If you can't tolerate gluten, look for gluten-free baking powder. When you're baking, remember that wheat-free and gluten-free flour may be drier, may not rise as much, and may have a crumbly texture.
