AMMONIUM SALTS of PHOSPHATIDIC ACID
Prepared at the 55th JECFA (2000) and published in FNP 52 Add 8 (2000), superseding tentative specifications prepared at the 17th JECFA (1973) and published in FNP 4 (1978) and in FNP 52 (1992). An ADI of 0-30 mg/kg bw was established at the 18th JECFA (1974).
SYNONYMS Ammonium phosphatides, Emulsifier YN, Mixed ammonium salts of phosphorylated glycerides; INS No. 442
DEFINITION The product consists essentially of a mixture of the ammonium compounds of phosphatidic acids derived from the edible fat (usually partially hardened rapeseed oil). A mono- or diglyceride moiety may be attached to phosphorus.
Moreover, two phosphorus esters may be linked together as phosphatidyl phosphatides. The product is prepared by glycerolysis of the fat, followed by phosphorylation with phosphorus pentoxide, and neutralization with ammonia.
The article of commerce may be further specified as to water content, hexane-insoluble matter, inorganic hexane-insoluble matter, pH value and
triglyceride content.
Assay The phosphorus content is not less than 3.0% and not more than 3.4% by weight; the ammonium N content is not less than 1.2% and not more than 1.5%.
DESCRIPTION Unctuous semisolid
FUNCTIONAL USES Emulsifier
