Galaktomannaani

Galaktomannaani is a type of polysaccharide, a complex carbohydrate, derived from the seeds of certain legumes, most notably the guar bean. It is a galactomannan, meaning its structure consists of a mannan backbone with galactose units attached. This specific chemical structure gives galactomannaani its unique properties.

Primarily, galactomannaani is known for its excellent water-binding capabilities. When dispersed in water, it forms a viscous solution or gel. This gelling and thickening property makes it a widely used food additive, often listed as E412. In the food industry, it functions as a stabilizer, thickener, and emulsifier, improving the texture and mouthfeel of various products such as ice cream, yogurt, sauces, and baked goods. It can also help to prevent the formation of ice crystals in frozen desserts and extend the shelf life of some foods by retaining moisture.

Beyond its food applications, galactomannaani has found uses in other industries. In pharmaceuticals, it can serve as a binder in tablets and as a component in controlled-release drug delivery systems. Its laxative properties have also been recognized, and it is sometimes used in dietary supplements aimed at promoting digestive regularity. In the cosmetics industry, its thickening and moisturizing properties are utilized in lotions and creams. The extraction process typically involves dehulling and grinding the guar seeds, followed by separation and purification of the galactomannaani.
