Any bad experience with King Arthur Gluten-free bread flour

[Sanna King]

King Arthur Gluten-free bread flour contains wheat starch, but has had the gluten removed. According to the FDA, it meets the FDA's gluten-free standard of less than 20 parts per million (ppm) of gluten. Has anyone here tried to bake bread from this? If yes, did you have a reaction? Thank you in advance for your time and attention.

It looks like you are referring to this product:
https://shop.kingarthurbaking.com/items/gluten-free-bread-flour

Their site says: "Made with gluten-free wheat starch to give baked goods incredible taste and texture, it’s ideal for classic yeasted recipes like artisan boules, bagels, cinnamon rolls, and burger buns", and it is true that Codex quality wheat starch is gluten-free, and does make better baked goods. However, it also contains very low levels of gluten (under 20ppm), and some celiacs do react to this level, so if you are super sensitive it's best to avoid it.

They also make this very similar product, which doesn't include any wheat ingredient, and is certified gluten-free:

Although labeling products in the USA as "gluten-free" that contain such wheat starch is relatively new, it has been offered in Europe for decades. You can read more about studies on it here:

Be very careful with this product! My wife who is not celiac but gluten intolerant since going gluten free for my daughter who is very sensitive celiac, got very sick as did I after baking with this flour. I have just been diagnosed with celiac and am not very sensitive yet. We baked second loaf a week later and got sick again. No Also, Mr Adams, the flour your post has a link to as being wheat free, also contains wheat starch. Read the allergen link.

Correction:

meant to say Note also. Not No also. Sorry, as that sounded a bit confrontational.

You are correct--my bad! The ingredients do include wheat starch, and the fact that their products are certified gluten-free means that they test below 10ppm, but again, some celiacs do report issues with products that use Codex wheat starch. Here is the label of the one I though was wheat-free:

Not all of King Arthur’s gluten free flours and baking mixes are certified gluten free. This bread flour is not.

You are right! The logo the have on their packages got me confused--it looks like they are less than 20ppm, not certified GF. Thanks for catching that!

Ingredients

Gluten-Free. Contains wheat.

The gluten-free wheat starch used in this product goes through additional gluten-free testing using both the R5 ELISA Sandwich and R5 ELISA Competitive methods to ensure it meets standards. Once produced, the final Gluten-Free Pizza Flour and Gluten-Free Bread Flour are tested again to ensure a strict gluten-free standard of less than 20ppm, with a target of less than 10ppm, is met for the finished product.

My brain also zeroed in on this "less than 10ppm" but I should have seen the rest...
