About this ruling
- Evidence confidence
- High means this page cites a primary regulator listing, retrieved 15 August 2026. That describes the quality of the sources on this page—not a Halal certificate for the pack or outlet in your hand.
Sodium citrates (E331, INS 331) are acidity regulators and sequestrants made from citric acid and sodium salts.

Additive identity
Possible source pathways
The finished molecule can be identical across feedstocks. The Halal ruling follows the pathway, not the code alone.
- microbial · Typical Halal Citric acid is almost always made by fermenting plant sugars (often Aspergillus niger on molasses or starch hydrolysate), then neutralised with sodium carbonate or hydroxide.
- plant · Typical Halal The carbohydrate feedstock is plant; no animal tissue is required for standard food-grade E331.
- synthetic Halal Mineral sodium salts plus fermented citric acid remain Halal.
Why this ruling
Sodium citrates—E331 on EU and many international labels, INS 331 in Codex, and usually sodium citrate or trisodium citrate on US packs—are the sodium salts of citric acid. They buffer tartness, sequester metals, and help processed cheese melt. The Halal question people bring from emulsifier lists does not belong here.[1][2]
Industrial citric acid is made by fermenting plant carbohydrates, typically with Aspergillus niger, then purified and reacted with sodium carbonate or sodium hydroxide to give the mono-, di-, or trisodium salt. EFSA’s re-evaluation of E330–E333 treats that identity as a family of citrate salts; it is a food-safety opinion, not a religious certificate.[2] Codex lists the same salts under INS 331.[4] None of those identity documents require an animal tissue feedstock.
So the additive itself is Halal. What still needs a look is the rest of the recipe: a sports drink with E331 can still carry E471, carmine, or gelatin gummies in the same brand line. Citric esters of mono- and diglycerides (E472c) are a different molecule with the E471 fat-source problem—do not file them under this page.
US shoppers will almost never see “E331”; they will see sodium citrate in cheese sauces, sodas, and club soda mixes. That string, INS 331, and E331 are the same analysis.
Where you'll find it
- Soft drinks and juice drinks (tartness, buffering)
- Processed cheese and dairy desserts
- Jams, jellies, and confectionery acids
- Meat brines and emulsified sauces as a sequestrant
How to verify
1) Match sodium citrate, sodium citrates, trisodium citrate, or E331 / INS 331. 2) Treat the additive as Halal. 3) Still check other ingredients on the same pack (E471, gelatin, carmine, alcohol flavourings). 4) Do not confuse citrate salts with citrate esters of mono- and diglycerides (E472c).
- E331 / sodium citrate = fermented citric acid + sodium → Halal.
- Do not confuse with E472c or E471.
- Still vet the rest of the ingredient list.
Conditions for Halal
- Food-grade sodium citrates / E331 from fermented citric acid → Halal
- Do not treat E472c (citric esters of mono- and diglycerides) as the same additive
- Finished drinks and cheeses still need their other ingredients checked
Scholarly differences
There is no named madhhab split on sodium citrate as a salt of fermented citric acid. Residual processing-aid questions that apply to some enzymes do not attach to standard E331 identity in EU or Codex listings. Do not import the E471/E472 source-dependent ruling onto citrate salts.
