ABSTRACT:
Stable oil-in-water emulsions are prepared containing a relatively high concentration of from 8 to 60% by weight of a heteropolysaccharide bipolymer, e.g., xanthan gum preferably, the emulsions contain greater than 15 up to 60% biopolymer, 40 to 99 parts of an aqueous phase containing 10 to 60% by weight biopolymer and 40% to 90% by weight water, 1 to 60 parts oil and 1 to 40% with respect to the aqueous phase and oil of a surface active agent. The emulsions are prepared by combining powdered biopolymer with water, oil and surfactant or by concentrating an oil-in-water emulsion containing the biopolymer such as by ultrafiltration. A fermentation wort containing the biopolymer may be used in preparing the emulsion.
