YenzoWhat is E335 (sodium tartrates)?
Appendix 1 of Circular 24/2019/TT-BYT lists the functions of disodium L(+)-tartrate as acidity regulator, emulsifying salt, sequestrant and stabilizer.
E335Sodium tartrates
E335 covers the sodium tartrates, sodium salts of tartaric acid: monosodium tartrate (335(i)) and disodium tartrate (335(ii)). In food they adjust acidity and help keep products stable.

Is sodium tartrates harmful?
In 2020 EFSA set a group ADI of 240 mg/kg body weight per day, expressed as tartaric acid, for L(+)-tartaric acid and tartrates (E 334–E 337, E 354), replacing the earlier 30 mg/kg. In the exposure scenario EFSA judged most relevant, intake in the population groups did not exceed this ADI. When tartaric acid from other additives (E 353, E 472d, E 472e, E 472f) and from natural occurrence is added, the 95th-percentile intake in toddlers would exceed the ADI; EFSA did not consider this to indicate a possible health concern because the exposure was overestimated.
Is Disodium L(+)-tartrate permitted in Vietnam?
Yes, for disodium L(+)-tartrate (INS 335(ii)), which is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food. Appendix 1 has no separate row for 335(i).
Can children and pregnant women have E335?
In the EU, additives may not be used in foods for infants and young children unless Annex II of Regulation (EC) No 1333/2008 provides for it. Annex II lists E335 in category 13.1.3 (processed cereal-based foods and baby foods), but only the L(+) form and only in biscuits, rusks and baby foods. The Regulation has no separate provision for pregnant women. If you have a particular health condition, ask a doctor.
