Ammonium Phosphatides

About

What it is and where it shows up.

Ammonium phosphatides are a group of emulsifiers consisting of mixed ammonium salts of phosphorylated glycerides, typically derived from rapeseed oil. They are primarily used in chocolate and cocoa-based confectionery products to control viscosity and improve texture.

Safety summary

The regulatory and scientific consensus.

An ADI of 30 mg/kg body weight per day was established by JECFA (1974) and the Scientific Committee on Food (1978), and confirmed unchanged by EFSA in its 2016 re-evaluation. At maximum permitted regulatory levels, exposure is below the ADI for all population groups except toddlers at high exposure; at realistic/refined use levels, all groups remain within the ADI. The substance demonstrates low acute oral toxicity, no genotoxicity concern, and no reproductive or developmental toxicity at doses tested.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
EFSA (European Food Safety Authority) (European Union)	Approved	Authorised under Annex II and Annex III of Regulation (EC) No 1333/2008; purity criteria defined in Commission Regulation (EU) No 231/2012. EFSA 2016 re-evaluation confirmed ADI at 30 mg/kg bw/day; toddlers at maximum regulatory exposure may slightly exceed ADI. EFSA also recommended revision of impurity limits for toxic elements (As, Cd, Pb, Hg) in EU specifications.source
FDA (Food and Drug Administration) (United States)	Approved	Filed under GRAS Notice GRN 219 for use primarily in cocoa and chocolate products. Ammonium phosphatides are not broadly listed in the FDA EAFUS substances-added-to-food inventory under this name; use is limited compared to EU.source

Who should approach with care

Whose guidance would steer them away.

Infants — EFSA (2016) found that toddlers at high dietary exposure can slightly exceed the established ADI of 30 mg/kg bw/day when maximum regulatory use levels are applied, warranting prudent intake management.

Children — Younger children have proportionally higher relative exposure per kilogram of body weight; EFSA identified toddlers as the most exposed population group with potential for marginal ADI exceedance.

Ibd — Experimental and epidemiological research indicates that emulsifiers including ammonium phosphatides may adversely affect intestinal microbiota composition and the gut metabolome, raising concern for individuals with inflammatory bowel disease.
