Post Time: 10097 Views

Guar gum (E412), a natural galactose, has the largest molecular weight in natural water-soluble polymer, is extracted from guar beans. It’s the white to pale yellow free-pouring powder, dissolve in cold water or hot water, form gelatinoid when mixing with water. Guar gum is the natural thickener and thus generate extremely high viscosity.

Guar Gum(E412)


Molecular Structure of Guar Gum(E412)


Sugars galactose and mannose compose guar gum, a polysaccharide. Beta 1-4 Glycosidic linkages couple the mannose units and the galactose side chains are linked through alpha 1-6, forming short side-branches.


Uses of Guar Gum in Food Industry


Frozen foods:  for ice-scream, paste, frozen cake, play roles in retaining moisture and stability

Fast food: for instant noodles, keep noodles pliable and tough

Baked food: for bread, pastries, and crust, used as dough enchancer to prolong shelf life

Dairy product: for Yogurt, jelly and sauce, play roles in retaining the texture after sterilization

Topping and sauce: for salad dressings, pickles, and gravy, used as emulsion stabilizer

Beverage: for Coconut milk, beer, fructose and sugar-free drinks, used as sntiacid, thickener, foam stabilizer, suspension.

Cheese production: increase condensation rate and tenderness


Properties of Guar Gum(E412)


Soluble in hot and cold water but insoluble in most organic solvents.

Has the excellent properties of thickening, emulsion, stabilizing and film forming.

Has the property of settling, play roles in filtering aid.

Compatible with different kinds of inorganic and organic substances

The viscosity of guar gum is influenced by temperature, ph and so on.


Potential side effects of Guar Gum(E412)


Guar gum expands quickly and very difficult to control once consumed and combined with liquid. High doses can cause pulmonary embolism , esophageal tear, small bowel obstruction and so on. Therefore, heavy use of guar gum is avoidable in any form of supplements, including diet pill.
