DescriptionGalactomannan, also known as galactomannan type i, is a member of the class of compounds known as oligosaccharides. Oligosaccharides are carbohydrates made up of 3 to 10 monosaccharide units linked to each other through glycosidic bonds. Galactomannan is soluble (in water) and a very weakly acidic compound (based on its pKa). Galactomannan can be found in a number of food items such as arabica coffee, fenugreek, soy bean, and coconut, which makes galactomannan a potential biomarker for the consumption of these food products. In order of increasing number of mannose-to-galactose ratio: fenugreek gum, mannose:galactose ~1:1 guar gum, mannose:galactose ~2:1 tara gum, mannose:galactose ~3:1 locust bean gum or carob gum, mannose:galactose ~4:1 cassia gum, mannose:galactose ~5:1 Galactomannans are often used in food products to increase the viscosity of the water phase .
