Acetic acid esters of mono- and diglycerides

Acetic acid esters of mono- and diglycerides (E472a) are partial acetic acid esters of glycerides derived from edible fats. They function as emulsifiers and dough conditioners in bread, pastry, and other baked goods, improving gas retention, dough elasticity, and crumb softness. They are metabolised by hydrolysis in the gut to acetic acid, glycerol, and fatty acids — all normal metabolic components.

JECFA's ADI is "not specified," evaluated in 1973, consistent with their complete metabolic conversion to ordinary dietary constituents. The acetic acid component (essentially vinegar) and the glycerol and fatty acid components are all normal human metabolites. No adverse effects have been identified at any dietary dose, and this class of emulsifiers has a long, well-established safety record.

Acetic acid esters of mono- and diglycerides are approved in the EU, US (GRAS), UK, and globally. They are found in commercial bread, pastry, and baked goods where dough conditioning is important for consistent texture and volume. For the general population there are no health concerns. As partially natural emulsifiers derived from food-grade fats, they occupy a position between purely synthetic emulsifiers and natural lecithin.
