Listed as a sequestrant by Canada.
Listed as sequestrants (CA)
- Canada: Sequestering agent — Health Canada, List of Permitted Sequestering Agents (List 12)
The calcium salt of phytic acid, used as a sequestrant — phytate binds metal ions strongly, which is both why it is used here and why it interferes with mineral absorption in cereals.

How much is permitted
A listing usually limits the quantity as well as the food. Only one of the forms that takes is a figure: quantum satis and good manufacturing practice permit the amount the technological effect requires and no more, which is a limit rather than the absence of one. Figures below are the range across every food category this page is listed in, and categories differ between regulators — see how much is permitted.
| Canada | — | 1 GMP |
|---|---|---|
| Japan | — | 1 no quantity stated |
No regulator sets a figure for Calcium phytate. That is not an absence of control: where the listing says quantum satis or good manufacturing practice, the quantity is limited to what the effect requires.
What FDA’s inventory records
This page holds no listing for Calcium phytate in the parts of 21 CFR this site reads. FDA’s Substances Added to Food inventory does carry it, as CALCIUM PHYTATE, pointing at no regulation at all.
The inventory is an information resource: a row means FDA holds information about the substance’s use in food, not that the substance is listed for that use. It is shown apart from the permissions above and is not counted as a US permission anywhere on this site.
What it is made from
Phytic acid is obtained from cereal brans and neutralised with a calcium source.

Common questions
Assembled from what is above, in the words the questions are usually asked in. Each answer is the same statement the relevant section makes, with the same citations behind it.
- What is Calcium phytate?
- The calcium salt of phytic acid, used as a sequestrant — phytate binds metal ions strongly, which is both why it is used here and why it interferes with mineral absorption in cereals.
- What is Calcium phytate used for in food?
- It is listed as a sequestrant — the role Canada assigns it. This page shows every function each regulator records, with the citation for each.
- Where is Calcium phytate permitted?
- Of the seven regulators this site reads, Canada and Japan permit it. Each permission is for named foods at named levels, not a blanket one; the table on this page gives them with citations.
- Is Calcium phytate vegan?
- Yes. Calcium phytate is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
