Standard for use (사용기준) of 황산망간: (1) [to be used under the general standard for use in II. 2. 1), the minimum amount that achieves the technical effect, with no limit set for this additive in particular] “II. 2. 1)의 규정에 따라 사용하여야 한다.” The Korean is the standard as published.

Compositional specifications (Part IV) are not imported, nor are the general standards in Part II, which apply to every additive.

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—2 GMP
South Korea—1 no quantity stated
United States—1 no quantity stated

No regulator sets a figure for Manganese sulfate. 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 it is made from

Produced by dissolving manganese ore or oxide in sulfuric acid.

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 Manganese sulfate?
Manganese sulfate is a manganese source in fortified foods and supplements.
What is Manganese sulfate used for in food?
It is listed as an acidity regulator, a nutrient supplement and a yeast food — the role Canada and the US assign it. This page shows every function each regulator records, with the citation for each.
Is Manganese sulfate banned in Europe?
No. Manganese sulfate does not appear on the EU's list of authorised food additives, which is not the same as being banned: the EU permits an additive only where it has authorised it, and usually the reason for an absence is that no one applied. The EU has made no finding against this substance. It does mean it may not be used as a food additive in the EU today.
Where is Manganese sulfate permitted?
Of the seven regulators this site reads, Canada, South Korea and the US 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 Manganese sulfate vegan?
Yes. Manganese sulfate is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
