E1517 - Glyceryl diacetate

Origin

Glyceryl diacetate, also known as diacetin, is a synthetic glycerol ester produced by the esterification of glycerol with acetic acid or acetic anhydride. It is a clear, colorless to slightly yellow, viscous liquid at room temperature. It is miscible with water and many organic solvents. It can also be derived from vegetable oils.

Usage

Glyceryl diacetate is primarily used as a humectant, plasticizer, and solvent in food products. It helps to retain moisture, improve texture, and dissolve other ingredients. It is commonly found in flavorings, baked goods, confectionery, and processed foods. It is also used in the production of cellulose acetate films and as a solvent in the pharmaceutical and cosmetic industries. In food, it can be used as a carrier solvent for flavors and colors. It is also used in animal feed.

Side Effects

Glyceryl diacetate is generally recognized as safe (GRAS) by regulatory bodies like the FDA when used in accordance with good manufacturing practices. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) 'not specified', meaning that, based on available data, the intake of glyceryl diacetate at levels necessary to achieve the desired technological effect does not represent a health concern. However, excessive consumption of foods containing high levels of glyceryl diacetate may cause mild gastrointestinal discomfort in some individuals. There is no evidence to suggest that glyceryl diacetate is carcinogenic or mutagenic. Allergic reactions are rare.

Regulatory Status

Glyceryl diacetate is approved for use as a food additive in many countries, including the United States, the European Union, and Canada. In the EU, it is designated as E1517. Regulatory limits vary depending on the specific application and jurisdiction. The FDA considers it GRAS under specific conditions of use. JECFA has evaluated and approved its use in food.
