Product Details

Xanthan Gum USP NF BP IP FCC Food Grade
Synonyms: Polysaccharide gum produced by the fermentation of carbohydrate with the bacterium Xanthomonas campestris
CAS Number: 11138-66-2, Molecular Weight: polymer, Chemical Formula: (C35H49O29)n, EINECS EC Number: 234-394-2, FEMA: ----,

Xanthan Gum BP Grade
Ph Eur
Action and use: Excipient.

DEFINITION
High-molecular-mass anionic polysaccharide produced by fermentation of carbohydrates with Xanthomonas campestris.
Xanthan gum has a relative molecular mass of approximately 1 × 106. It exists as the sodium, potassium or calcium salt.
Content: Minimum 1.5 per cent of pyruvoyl groups (C3H3O2; Mr 71.1) (dried substance).

CHARACTERS
Appearance: White or yellowish-white, free-flowing powder.
Solubility: Soluble in water giving a highly viscous solution, practically insoluble in organic solvents.
IDENTIFICATION
A. In a flask, suspend 1 g in 15 ml of 0.1 M hydrochloric acid . Close the flask with a fermentation bulb containing barium hydroxide solution and heat carefully for 5 min. The barium hydroxide solution shows a white turbidity.
B. To 300 ml of water, previously heated to 80 °C and stirred rapidly with a mechanical stirrer in a 400 ml beaker, add, at the point of maximum agitation, a dry blend of 1.5 g of carob bean gum and 1.5 g of the substance to be examined. Stir until the mixture forms a solution, and then continue stirring for 30 min or longer. Do not allow the water temperature to drop below 60 °C during stirring. Discontinue stirring and allow the mixture to stand for at least 2 h. A firm rubbery gel forms after the temperature drops below 40 °C but no such gel forms in a 1 per cent control solution of the sample prepared in the same manner but omitting the carob bean gum.

TESTS
pH: 6.0 to 8.0 for a 10.0 g/l solution.
Viscosity: Minimum 600 mPa·s.
2-Propanol: To pass Gas chromatography test. Limit 2-propanol: maximum 750 ppm.
Other polysaccharides: To pass Thin-layer chromatography test.
Loss on drying: Maximum 15.0 per cent, determined on 1.000 g by drying in an oven at 105 °C for 2.5 h.
Total ash: 6.5 per cent to 16.0 per cent.
Microbial contamination: Total viable aerobic count not more than 103 bacteria and 102 fungi per gram, determined by plate count. It complies with the test for Escherichia coli.

DESCRIPTION
Xanthan Gum occurs as a cream colored powder. It is a high-molecular-weight polysaccharide gum produced by a pureculture fermentation of a carbohydrate with Xanthomonas campestris, purified by recovery with isopropyl alcohol, dried, and milled. It contains D-glucose and D-mannose as the dominant
hexose units, along with D-glucuronic acid and pyruvic acid, and it is prepared as the sodium, potassium, or calcium salt. It is readily soluble in hot or cold water, but it is insoluble in alcohol. Its solutions are neutral.
Function: Stabilizer; thickener; emulsifier; suspending agent; bodying agent; foam enhancer.

REQUIREMENTS
Identification: Transfer 300 mL of water, previously heated to 80°, into a 400-mL beaker and stir rapidly with a mechanical stirrer. At the point of maximum agitation, add a dry blend of 1.5 g of sample and 1.5 g of locust bean gum. Stir until the mixture goes into solution, and then continue stirring for 30 min longer. Do not allow the water temperature to drop below 60°. Discontinue stirring, and allow the mixture to cool at room temperature for at least 2 h. A firm, rubbery gel forms after the temperature of the mixture drops below 40°. No such gel forms in a 1% control solution of sample prepared in the same manner but omitting the locust bean gum.
Assay: A sample yields, on the dried basis, not less than 4.2% and not more than 5.4% of carbon dioxide (CO2), corresponding to between 91.0% and 117.0% of Xanthan Gum.
Isopropyl Alcohol: Not more than 0.075%.
Lead: Not more than 2 mg/kg.
Loss on Drying: Not more than 15.0%.
Pyruvic Acid: Not less than 1.5%.
Viscosity: Passes test.
