You're thinking of Beta-Glucan, not Gluten. The former, a carbohydrate, gums up mashes. The latter, a protein, causes bloating and digestive issues in some people.
gluten is the mesh that forms with kneading between the two protiens gliadin, and the other one? and water and time does it too, i thought?
and this is a mash, i don't think we want to make seitan here? unless this is specifically for dog treats?
