What Is Locust Bean Gum?
Locust bean gum (carob bean gum) is a galactomannan polysaccharide extracted from the seeds of the carob tree (Ceratonia siliqua). It functions as a thickener and stabilizer in ice cream (preventing ice crystal formation), dairy products, sauces, and processed meats. A key property is its synergistic interaction with xanthan gum (E415) and carrageenan (E407) — mixtures produce stronger, more elastic gels than either alone. JECFA considers it acceptable with no ADI. EFSA confirmed safety in 2017. Approved globally and classified as dietary fiber.
? Did You Know?
Locust Bean Gum occurs naturally in Carob tree seeds (Ceratonia siliqua) and Mediterranean region native trees. Many people consume it daily without realizing it's also a listed food additive.
Beyond food, Locust Bean Gum is also used in cosmetics, medicine, industrial applications. Its versatility makes it one of the most multi-purpose chemical compounds in everyday life.
In the EU, Locust Bean Gum has a "quantum satis" authorization — Latin for "as much as needed." This means there's no specific maximum limit; manufacturers use only what's technologically necessary.

Natural Occurrence
A natural galactomannan polysaccharide extracted from the seeds of the carob tree. The carob tree is native to the Mediterranean region and has been cultivated for thousands of years.
Manufacturing
Seeds are removed from carob pods, roasted to split the hull, then the endosperm is separated, ground into powder, and purified to produce locust bean gum.
Applications Beyond Food
Used in cosmetics and personal care products as a thickener.
Used in pharmaceutical formulations as a binder and disintegrant.
Used in textile printing, paper manufacturing, and oil drilling.
