Disodium DL-Tartrate (Disodium dl-Tartrate) DL－酒石酸ナトリウム（別名dl－酒石酸ナトリウム）
Designated additiveNot on the EU additive list
- 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), “酒石酸塩（K、Na）” (tartrate (K, Na))
- Name in the List of Designated Additives
- DL－酒石酸ナトリウム（別名dl－酒石酸ナトリウム） (No. 212)
In Japan
- The sodium salt of the DL form of tartaric acid. It falls within the group names for acidulant, pH adjuster, and seasoning (organic acids).
- 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), the same as for the L form. 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 not on the EU list of food additives (Regulation (EC) No 1333/2008, Annex II), so it cannot be used as a food additive in the EU.
- The form permitted in the EU as tartaric acid and tartrates (E334 to 337, E354) is the L(+) form; the DL form is not included (EFSA 2020 re-evaluation)
When it is labeled under a shared name
Disodium DL-Tartrate (Disodium dl-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.
