Do flours or starches need to be labelled as modified if they are?

QUESTION:

I’m wondering whether flours or starches need to be labelled as modified if they are? Specifically I purchased flour with the ingredients GF flour (Rice, tapioca, potato), guar gum. However I purchase bread from the same company with similar ingredients and it says modified tapioca starch.

ANSWER:

In my experience most starches are modified (regardless of whether they are labelled as such). Starches can be cooked or roasted, treated with enzymes, or with various chemicals.

I would say 90% of the time I have questioned a manufacturer on a starch, it has turned out to be modified. Personally, I avoided starches.
