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.

How JECFA defines it

INS 335(ii) Sodium L(+)-Tartrate

Synonyms: Sodium dextro-tartrate; INS No. 335(ii)

Description and assay

Specification history
Prepared at the 7 th JECFA (1963), published in NMRS 35 (1964) and in FNP 52 (1992). Metal and arsenic specifications revised at the 63 rd JECFA (2004) (identical to those listed for potassium sodium L(+)-tartrate). An ADI of 0-30 mg/kg bw was established at the 17 th JECFA (1973) and reconfirmed at the 21 st JECFA (1977).

DESCRIPTION
Transparent, colourless and odourless crystals
FUNCTIONAL USES
Sequestrant and stabilizer in meat products and sausage casings
METHOD OF ASSAY
Weigh 1.500 g of the dried sample into a tared porcelain crucible, ignite gently at first, until the salt is thoroughly carbonized, protecting the carbonized salt from contact with the flame at all times. Cool the crucible, place in a glass beaker and break up the carbonized mass with a glass rod. Without removing the glass rod or the crucible, add 50 ml of water, 50 ml of 0.5 N sulfuric acid, cover the beaker, and boil the solution for 30 min. Filter, and wash with hot water until the last washing is neutral to litmus. Cool the combined filtrate and washings, add methyl orange TS, and titrate the excess acid with 0.5 N sodium hydroxide. Each ml of 0.5 N sulfuric acid is equivalent to 0.0485 g of C4H4Na2O6. Alternative method of assay: Weigh 0.4500 g of the dried sample and transfer to a 250-ml beaker. Add 100 ml of glacial acetic acid, and stir the solution (e.g. with a magnetic stirrer) until the sample is dissolved. Titrate the solution with 0.1 N perchloric acid in glacial acetic acid, adding the titrant in 0.2-ml increments as the end-point is neared, and determine the end-point by the potentiometric method. Each ml of 0.1 N perchloric acid is equivalent to 0.0097 g of C4H4Na2O6.

Hazard reference values

The two committees set different figures. EFSA's acceptable daily intake is 240 mg/kg bw/day (2020); JECFA's is 30 mg/kg bw/day (1973). An acceptable daily intake is a reference value set by a committee, not a threshold above which harm begins. The lower figure is not a finding that the other body was wrong: the two work to different terms of reference, on their own timetables, and sometimes from different data. This site states both and chooses between them nowhere. See where the two committees differ.

Values set by assessing bodies. A body that has not set a value is not listed here.

Evidence and how bodies read it

What assessing bodies concluded

Each conclusion is paraphrased in the body's own framing, from the published opinion linked beneath it. Where bodies differ, both stand; this site does not adjudicate between them or add a view of its own.

  1. EFSA 2020

    The FAF Panel found no genotoxic or carcinogenic potential for L(+)-tartaric acid and tartrates (E 334–E 337, E 354) and, using a chemical-specific uncertainty factor based on lower internal exposure in humans than rats, established a group ADI of 240 mg/kg bw/day expressed as tartaric acid (the SCF had set 30 mg/kg bw/day). Refined exposure estimates did not exceed the group ADI.

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 E 335?
E 335 is Sodium tartrate. Sodium tartrate is an acidity regulator and sequestrant used in confectionery, jams and dairy products.
What is Sodium tartrate used for in food?
It is listed as an emulsifier, an acidity regulator and a stabiliser — the role Canada, the US and Codex assign it. This page shows every function each regulator records, with the citation for each.
Where is Sodium tartrate permitted?
Of the seven regulators this site reads, Australia and New Zealand, Canada, the EU, Great Britain, Japan, South Korea, the US and the Codex standard 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 Sodium tartrate vegan?
Yes. Sodium tartrate is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
