Dodecyl gallate

Dodecyl gallate is a synthetic antioxidant, often produced by esterifying gallic acid with dodecanol. Gallic acid itself is a naturally occurring compound found in plants like gallnuts, sumac, and tea leaves.

Manufacturers add dodecyl gallate to foods as an antioxidant to prevent fats and oils from becoming rancid, thereby extending shelf life. It is commonly found in products containing fats and oils, such as vegetable oils, shortenings, margarines, and some processed meats.

Dodecyl gallate is an authorised food additive in Great Britain, listed on the Register of Food Additive Authorisations. European authorities, including EFSA, have evaluated its safety. JECFA has also evaluated it and set an acceptable daily intake. While generally considered safe at typical intake levels, some individuals may experience allergic reactions or skin sensitivity. Evidence regarding potential long-term health effects is mixed, and it has been the subject of some debate, though regulatory bodies maintain its safety under current usage conditions.
