E1517: Glyceryl Diacetate
Main role: carrying ingredients
Also listed as: diacetin, glycerol diacetate
What is E1517 (Glyceryl Diacetate)?
Glyceryl diacetate is an ester preparation made from glycerol and acetic acid. It can function as a carrier in specified ingredient preparations, depending on the permitted use.
What does it do in food?
Its main role is carrying ingredients. A carrier helps incorporate another ingredient, while a processing ingredient may support a manufacturing step or coating. The final declaration and exposure depend on the application and the labeling rules in the relevant market.

Label names and ingredient questions
Look for E1517, E 1517, or the ingredient name. Related names and label terms include diacetin, glycerol diacetate. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Diacetin and triacetin have different degrees of acetylation. Their related names do not imply identical composition or use conditions.
Is E1517 safe?
There is no meaningful personal risk estimate from an E number alone. Food-grade specifications, allowed uses, amount consumed, and individual circumstances all matter. The authorization record below gives the legal scope; it is not a claim that every possible use is appropriate.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E1517 as Glyceryl diacetate (diacetin). This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
