What is the water-soluble fraction of tragacanth?

Constituents. Tragacanth consists of a water-soluble fraction known as tragacanthin and a water-insoluble fraction known as bassorin; they have molecular weights of the order of 840 000. Both are insoluble in alcohol.

Is tragacanth an emulsifier?

23.5. 1.1 Food applications. Gum tragacanth has been used as a stabilizer, emulsifier, and thickener in food products.

Which of the following is water-soluble constituents from tragacanth?

Tragacanthin is water-soluble and further fractioned into ethanolic insoluble part, tragacanthic acid and ethanolic soluble part, arabinogalactan [103]. Both bassorin and tragacanthic acid are water insoluble in nature, but they can form viscous gel.

Why is tragacanth more viscous than acacia?

5.6. Tragacanth provides thixotrophy to a solution (forms pseudoplastic solutions). The maximum viscosity of the solution is achieved after several days, due to the time taken to hydrate completely. Tragacanth is stable at a pH range of 4-8. It is a better thickening agent than acacia.

How do you make a tragacanth solution?

In a 250 ml round-bottomed flask, place 2.0 g of tragacanth and add 95 ml of methanol. Moisten the powder by swirling and add 80 ml of hydrochloric acid. Add a few glass beads of about 4 mm in diameter and heat under reflux in a water-bath for 3 h.

Which component of tragacanth and is water-soluble and water insoluble respectively?

… Tragacanth gum is a an exudate gum obtained from the stems and branches of Astragalus 5 which consists of water-soluble (30-40%) and water-insoluble (60-70%) fractions 6 . It is a GRAS additive that has been used as a stabilizer, emulsifier, thickener and etc 5, 7 .

What is the use of tragacanth?

Tragacanth is used both for diarrhea and constipation. It is also an ingredient in toothpastes, hand lotions, denture adhesives, and vaginal creams and jellies. In foods, tragacanth is important for stabilizing and thickening ingredients in salad dressings, foods, and beverages.

Which component of tragacanth and is water soluble and water insoluble respectively?

Is tragacanth a suspending agent?

Tragacanth is used as a suspending agent, emulsifier, thickener, and stabilizer.

What is tragacanth used for?

How do you dissolve tragacanth gum?

Gum tragacanth consists two major fractions: a water-soluble (tragacanthic acid and small amount of an arabinogalactan) and an insoluble but water-swellable fraction named bassorin. Tragacanthic acid and bassorin are insoluble in ethanol but arabinogalactan is soluble in a mixture of ethanol–water (7:3) [3].

What does tragacanth mean?

Definition of tragacanth : a gum obtained from various Asian or eastern European plants (genus Astragalus and especially A. gummifer) of the legume family that swells in water and is used chiefly as an emulsifying, suspending, or thickening agent.

How is tragacanth made?

The primary source of gum tragacanth is the desert highlands of northern and western Iran, particularly the Zagros Mountains region. In Iran, the gum is harvested seasonally by making an incision on the upper part of the taproot and collecting the exuding gum.

What is tragacanth with example?

Tragacanth is a natural gum obtained from the dried sap of several species of Middle Eastern legumes of the genus Astragalus [18]. It is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides. • Tragacanth provides thixotrophy to a solution (forms pseudoplastic solutions).

Is tragacanth a mucilage?

Powders using tragacanth as a basis were sometimes called diatragacanth. As a mucilage or paste, it has been used as a topical treatment for burns. It is used in pharmaceuticals and foods as an emulsifier, thickener, stabilizer, and texturant additive (E number E413).
