Soy Sauce

[Jenniferxgfx]

I saw a thread on another site about some celiac specialist who believes standard soy sauce does not contain any actual gluten because it's supposedly destroyed in the distillation process. As a chemist, this makes zero sense to me and I don't believe it. As a celiac, I react to soy sauce that's not gluten-free.

This specialist is in Finland, and supposedly does lots of research on the subject. Am I wrong here? There's no safe soy sauce unless it's gluten-free soy sauce, right?

Most, but not all, soy sauce also contains wheat. If this is the case, the sauce is not gluten-free. In the US and Canada, the word "wheat" will appear on the label in such a case.

I don't believe there is anything in the manufacturing process that would remove the gluten. Distillation does remove gluten, but soy sauce is fermented, not distilled.

Thank you. Fermented! That makes sense. I don't know a lot about soy sauce manufacturing but I didn't think distillation sounded right.

There was a discussion about Sunset Gourmet in June, who made the same claim: that the gluten could be fermented out of soy sauce.

Thanks for this!

It makes me sad how ignorant these companies can be.
