What Is Refined Locust Bean Gum (Carob Gum, LBG) , 78% Galactomannan, FCC + EU 231/2012? Applications, Dosage, Alternatives & Specifications

Locust Bean Gum, also known as Carob Gum, LBG, Carob Bean Gum, is a natural high-molecular-weight water-soluble polysaccharide extracted from the endosperm of the seeds of the carob tree (Ceratonia siliqua), which is native to the Mediterranean region. It is an important category of galactomannan plant gums, with wide application value in the global food industry, pharmaceutical industry, cosmetic industry, and textile industry. Its CAS number is 9000–40–2, CNS number is 20.023, INS number is 410, and EU E number is E410. Locust Bean Gum appears as a white to yellowish-white powder, granules, or flat flakes, odorless or with a slight characteristic odor. Its chemical structure is a high-molecular-weight polysaccharide composed of a β-1,4-linked D-mannose backbone with α-1,6-linked D-galactose side chains. The mannose-to-galactose ratio is approximately 3.5–4.1:1. LBG is non-ionic and dissolves only in hot water, forming highly viscous solutions. It exhibits excellent synergistic gelling effects when combined with carrageenan, xanthan gum, or agar. Locust Bean Gum is one of the most important thickeners and stabilizers in the food industry, widely used in ice cream, dairy products, baked goods, meat products, jellies, preserves, sauces, pet food, as well as in pharmaceuticals, cosmetics, textiles, and oil drilling.

Parameter

Locust Bean Gum is recognized as the “king of synergistic gelling agents,” holding an irreplaceable position in the global food ingredient industry and other industrial fields. Its most outstanding core advantages lie in its unique synergistic gelling properties and wide application adaptability.
