Not authorised for use in UK or EU food.
Why it’s worth knowing. Not authorised for use in UK or EU food. Any UK product listing E344 or lecithin citrate as an additive would be in breach of food law.
Lecithin citrate is a compound formed by combining lecithin (a mixture of phospholipids found naturally in soy and egg yolk) with citric acid. It is assigned the Codex Alimentarius number INS 344. Although it carries an E-number, it has never been authorised for food use under EU or retained UK food additive law.
When used in food systems, lecithin citrate acts as both an emulsifier and an antioxidant synergist. The citric acid component chelates (binds) trace metal ions such as iron and copper that would otherwise catalyse the oxidation of fats. The lecithin component stabilises oil-in-water or water-in-oil interfaces. Together the compound can extend the shelf life of fat-containing foods by slowing rancidity.
Lecithin citrate is not used in UK or EU food products. Internationally, it is listed under the Codex Alimentarius (INS 344) and has been described as permitted in some fat-containing products such as shortenings, margarines, and edible oils in certain jurisdictions outside the UK and EU. On a label it would appear as 'lecithin citrate' or 'E344'; neither term should appear on any UK food product.
E344 does not appear in Annex II or Annex III of EU Regulation 1333/2008 on food additives, and is absent from the UK FSA approved additives list. This means no safety evaluation resulting in authorisation has been completed by EFSA or the former UK Advisory Committee on Novel Foods and Processes for this specific compound. The related substance lecithin (E322) is authorised, but lecithin citrate is a distinct chemical entity and its authorisation cannot be assumed from E322's approval.
E344 (lecithin citrate) is not listed in Annex II (permitted food additives) of EU Regulation 1333/2008 and does not appear on the UK FSA approved additives register.
Lecithin citrate is included in the Codex General Standard for Food Additives as INS 344, indicating some international recognition, but Codex listing does not confer EU or UK authorisation.
Lecithin citrate is a reaction product of lecithin and citric acid. The antioxidant synergist function comes from citric acid's ability to bind pro-oxidant metal ions. Published food chemistry literature describes this mechanism for similar phospholipid-acid compounds. No EFSA opinion on the safety of lecithin citrate as a food additive exists because the compound was never submitted for EU authorisation.
Citric acid esters of fatty acids and phospholipids can act as metal chelators, reducing free-radical chain reactions that cause fat oxidation, a mechanism established in food chemistry literature.
Under UK law, no food sold in the UK should contain E344. If you encounter it on a UK label, the product may be imported from a country where it is permitted, or there may be a labelling error. Report it to the UK FSA or your local trading standards office.
E344 is unusual in that it holds an international reference number (INS 344) and an E-number designation, yet has never been evaluated or authorised by EFSA for EU or UK food use. This is not uncommon: many substances have historical E-numbers assigned before the current centralised EU authorisation process was established, but were never formally cleared under it. The authorised relative, E322 (lecithin), has a clean regulatory record and no numerical ADI, but that clearance does not extend to this chemically distinct citric acid compound. The straightforward position is that it should not be present in any UK food product.
E344 is not on the UK FSA approved additives list, which means it is not permitted for use in food sold in the UK. It was never granted authorisation under EU Regulation 1333/2008, the law the UK retained after EU exit. Not being approved has the same practical effect as a ban for UK food products.
E-numbers are reference designations assigned to substances considered for food use. Some compounds received a number during earlier international harmonisation work under the Codex Alimentarius but were never formally evaluated and authorised under the EU's current centralised food additive approval process. Having an E-number does not mean a substance is approved in the UK or EU.
No UK or EU food product should legally contain E344. Internationally, lecithin citrate has been described as used in fat-containing products such as margarines, shortenings and edible oils in some countries outside the UK and EU.
It depends on the lecithin source. Lecithin citrate can be produced from soy lecithin (vegan) or egg yolk lecithin (not vegan). Since E344 is not authorised in UK or EU food, this question is largely academic for UK shoppers.
