Disodium L-Tartrate (Disodium d-Tartrate) L－酒石酸ナトリウム（別名d－酒石酸ナトリウム）
Designated additivePermitted in the EU (E335(ii))EFSA ADI 240mg per kg body weight per day
- Purpose
- acidulant, pH adjuster, seasoning
- On the label
- “酸味料” (acidulant), “pH調整剤” (pH adjuster), “調味料（有機酸）” (seasoning (organic acids)) (group names), “酒石酸ナトリウム” (sodium tartrate), “酒石酸Na” (sodium tartrate)
- Name in the List of Designated Additives
- L－酒石酸ナトリウム（別名d－酒石酸ナトリウム） (No. 213)
In Japan
- The sodium salt of L-tartaric acid. It falls within the group names for acidulant, pH adjuster, and seasoning (organic acids), and when used for those purposes it can be written under a group name.
- When written by substance name, the simplified names are “酒石酸ナトリウム” (sodium tartrate) and “酒石酸Na” (sodium tartrate). No standards for use have been set.
Japan's standards for use
There are no standards for use that limit which foods or how much (the general standards for all additives still apply).
This is a summary of the standards for use. See the source list for the exact conditions.
In the EU
- It is on the EU list of food additives (Regulation (EC) No 1333/2008, Annex II) as E335(ii).
- In its 2020 evaluation, EFSA (the European Food Safety Authority) set an ADI (acceptable daily intake) of 240mg per kg of body weight per day (a group ADI, for the total of related substances) (EFSA FAF).
When it is labeled under a shared name
Disodium L-Tartrate (Disodium d-Tartrate) may be declared on the label in the same way as “酸味料”. See Acidulant (acidity regulator) for details.

This page lists facts stated in laws and in evaluations by public bodies; it is not a safety verdict. Additives used in Japan are approved by the government, which sets the foods and amounts they can be used in. The ADI is a guide to the amount that is considered safe to take every day over a lifetime.
