GENERAL INFORMATION
Xanthan gum is a high molecular weight polysaccharide. In the late fifties the research laboratories of the US Department of Agriculture discovered that the bacterium Xanthomonas campestris found on cabbage plants produces a polysaccaride with exceptional properties. It is used as a rheology control agent in aqueous systems and as a stabilizer for emulsions and suspensions. Its numerous areas of applications cover a broad spectrum and range from the food industry to oil recovery.
CHARACTERISTICS
Xanthan gum is used as a stabiliser and thickener, suspending agent, bodying agent or foam enhancer in foods. Main characteristics are:
high stabilising properties
high viscosity at low concentration
soluble in hot and cold water
high pseudoplasticity
excellent freeze/thaw stability
very resistant to pH - variations
highly resistant to temperature variations
highly resistant to enzymatic degradation
very low caloric value
compatible with all commercial thickeners and stabilisers.
LEGAL ASPECTS
In 1969 xanthan gum was cleared as a food additive by the FDA for the US market. In 1980 the EC approved xanthan gum under the E-number 415. Many countries have set up specific rules concerning the use of food additives. We therefore advise to carefully investigate them before any use.
