DIACETYLTARTARIC and FATTY ACID ESTERS of GLYCEROL
Prepared at the 71st JECFA (2009) and published in FAO JECFA Monographs 7 (2009) superseding specifications prepared at the 57th JECFA (2001) and published in the Combined Compendium of Food Additive Specifications, FAO JECFA Monographs 1 (2005). An ADI of 0-50 mg/kg bw was established at the 61st JECFA (2003). SYNONYMS Diacetyltartaric acid esters of mono- and diglycerides; DATEM; Tartaric, acetic and fatty acid esters of glycerol, mixed; Mixed
acetic and tartaric acid esters of mono and diglycerides of fatty acids; INS No. 472e
DEFINITION The product consists of mixed glycerol esters of mono- and diacetyltartaric acid and fatty acids from edible fats and oils. It is made by the interaction of diacetyltartaric anhydride and mono- and diglycerides of fatty acids in the presence of acetic acid, or by interaction of acetic anhydride and mono- and diglycerides of fatty acids in the presence of tartaric acid. Because of inter- and intramolecular acyl-group exchange, both
methods of production lead to the same essential components, the distribution of which depends on the relative proportions of the basic raw materials, on temperature, and on reaction time. The product may contain small amounts of free glycerol, free fatty acids, and free tartaric and acetic acids.
