<<Disclaimer: Verify this information before applying it to your situation.>> I have wondered about the amount of gluten in wheat products too and have worked out this estimate (I worked pretty hard on this, but if anyone sees a flaw let me know): An average slice of white wheat bread contains 2.25 grams of protein About 75% of that protein is gluten So there are 1700 milligrams of gluten per slice If you divided that piece of white bread into 1700 pieces (41x41), then one of the pieces would contain about 1 mg gluten. That is, one crumb could contain about 1 mg gluten This amount will vary by product, because sturdy doughs such as pizza contain more gluten and soft products such as cake contain less. 50mg/1700 mg = .0294, so 3% of the slice of white bread would equal about 50 mg. gluten ----------------- Also, I have a formula for the amount of milligrams of gluten in GF products. Take the ppm of the product times the number of grams of the food that are eaten, and divide by 1000 to get the number of milligrams. So, if you have a 30g slice of GF bread contaminated at 20 ppm, then the number of milligrams of gluten in that slice is: 20x30/1000 = 0.6 mg 6 slices in a day would be 3.6 mg gluten - Diane Hosek *Support summarization of posts, reply to the SENDER not the CELIAC List* ******* To unsubscribe, email: mailto:[log in to unmask] *******
