Disodium succinate is the sodium salt of succinic acid. South Korea lists it as an acidity regulator and flavour enhancer under INS 364(ii), and FDA's inventory lists it as a flavouring (FEMA 3277). The site holds succinic acid on its own page. Japan also designates it (Appended Table 1, item 150).

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.
| Japan | — | 1 no quantity stated |
|---|---|---|
| South Korea | — | 1 no quantity stated |
No regulator sets a figure for Disodium succinate. 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 Disodium succinate in the parts of 21 CFR this site reads. FDA’s Substances Added to Food inventory does carry it, as DISODIUM SUCCINATE, pointing at a flavour industry number, with no 21 CFR citation, and FEMA number 3277.
Technical effects FDA records: flavor enhancer, flavoring agent or adjuvant.
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.

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 INS 364(ii)?
- INS 364(ii) is Disodium succinate. Disodium succinate is the sodium salt of succinic acid. South Korea lists it as an acidity regulator and flavour enhancer under INS 364(ii), and FDA's inventory lists it as a flavouring (FEMA 3277). The site holds succinic acid on its own page. Japan also designates it (Appended Table 1, item 150).
- What is Disodium succinate used for in food?
- It is listed as a flavour enhancer and a flavouring agent — the role the US assigns it. This page shows every function each regulator records, with the citation for each.
- Where is Disodium succinate permitted?
- Of the seven regulators this site reads, Japan and South Korea permit it. Each permission is for named foods at named levels, not a blanket one; the table on this page gives them with citations.
