Tragacanth Gum Pure Powder

Tragacanth pure powder (also known as Astragalus gum or Gum Tragacanth) is a natural secretion extracted from the plant Astragalus gummifer Labillardie (Tragacanth tree). After refining, it appears as a white gum powder with unique physical and chemical properties. Below are the detailed specifications of Tragacanth pure powder:

I. General Characteristics:

• Appearance: White to creamy white fine powder
• Loss on Drying: < 12%
• Viscosity: 400-600 centipoise
• pH (1% aqueous solution, 25°C): 4-5
• Heavy Metals: < 40 ppm
• Total Ash: < 4.0%

II. Properties and Functions of Tragacanth Pure Powder:

• Colorless and odorless, suitable for consumption: Tragacanth pure powder is a natural macromolecule with a slippery and viscous texture.
• Solubility characteristics: Part of Tragacanth is soluble in water, forming a transparent solution, while another part (Bassorin) absorbs water and swells to form a gel-like substance.
• Emulsifying properties: In low-acid environments (pH < 2), the gum properties of Tragacanth remain unaffected, making it suitable for oil-in-water emulsion stabilization without the need for additional surfactants.
• Viscosity and rheological properties: A 1% aqueous solution exhibits pseudoplastic fluid behavior, showing shear-thinning effects, which is advantageous for pipeline transportation.
• Solubility: Insoluble in alcohol, oils, and organic solvents. The pH of the aqueous solution typically ranges from 4 to 5, and changes in pH do not significantly affect the stability of the gum solution.
• Heat resistance: Temperature does not destructively affect its viscosity; viscosity temporarily decreases when heated but recovers upon cooling.

III. Industrial Applications:

Tragacanth pure powder has various industrial uses, primarily including:

• Pharmaceutical industry: Used as an emulsifying stabilizer, adhesive, suspension stabilizer, etc. For example, it is applied in the emulsification stabilization of cod liver oil, orange-flavored cod liver oil, mineral oil, and fat-soluble vitamins, or for the suspension stabilization of insoluble particles.
• Cosmetics industry: Used in oil-water stabilization systems for high-end cosmetics, such as hair creams and facial lotions.
• Food industry: Employed as an emulsifying stabilizer for acidic oil-water systems, such as French and Russian salad dressings, seasoning sauces, and sweet-and-sour sauces.

IV. Usage Method:

• Generally, a certain concentration of gum solution is prepared first and left for 10-20 hours to allow full hydration. If used under acidic conditions, the pH needs to be adjusted afterward.

V. Storage and Packaging:

• Storage: Should be stored in a cool, dry, and sealed environment to ensure long-term preservation.
• Packaging: 25kg/bag

VI. Other Information:

• Specifications: Complies with British Pharmacopoeia (BP 98), United States Pharmacopeia (USP XXIII), and Food Chemicals Codex (FCC) standards, and meets the European Community Food Additive Standard (E413).
