Acetic Acid Esters of MDG
The short version
Acetylated MDG (AcMG) — used as plasticizing agent and edible coating in bakery and confectionery.
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Where it comes from
Manufactured by acetylating mono- and diglycerides (E471) with acetic anhydride. The acetylation replaces some hydroxyl groups, lowering the melting point and changing crystallinity behavior.
How it's used
Used as a plasticizing agent in cake batters and icings (improves aeration and texture), as a moisture barrier in encapsulated flavors and edible coatings, and to stabilize powdered coffee whiteners.
Safety profile
ADI not specified — considered safe. Hydrolyzed in digestion like other glyceride esters to fatty acids, glycerol, and acetic acid.
Physical & chemical properties
Off-white to pale yellow waxy solid or viscous liquid depending on composition. Soluble in oils; partially water-dispersible.
Regulation worldwide
Permitted globally without restrictive limits.
