Your question: How do you test flour for gluten?

How can you tell if flour has gluten in it?

You can look for the protein level on the COA. The higher the percentage of protein in your flour, the more gluten there is in it. The amount of gluten in flour is determined by what type of wheat is used to make the flour.

How do you test gluten content?

Nima can detect gluten proteins in food in a matter of minutes. To test a sample of food, you insert a pea-size amount into a capsule, and then slide the capsule into the Nima sensor. The sensor is small — 3” by 3 1/2” — and weighs only 3 ounces. That makes it easy to stick in a purse, backpack, or back pocket.
