What Is Calcium iodate?
Calcium iodate is an inorganic iodine compound used as a flour treatment agent (dough conditioner) and as an iodine supplement in animal feed and some food applications. As a flour treatment agent, it acts as an oxidizing agent improving dough strength. JECFA considers it acceptable. Iodine is an essential trace mineral required for thyroid hormone synthesis; the recommended daily intake is 150 μg for adults. Calcium iodate is approved in several jurisdictions as a flour improver and in iodized salt programs. Its use as a direct food additive varies by country.

In the EU, Calcium iodate has a "quantum satis" authorization — Latin for "as much as needed." This means there's no specific maximum limit; manufacturers use only what's technologically necessary.
