ABSTRACT:
Process for the preparation of water continuous emulsions, containing 10 to 60 wt. % of dispersed oil. The emulsion contains protein obtained from egg, milk, vegetables or fruit, but no substantial amounts of polysaccharide thickeners. The process comprises the following steps (not necessarily in the indicated order) a. dispersing or dissolving the protein in either an aqueous phase or an oil phase, b. mixing the aqueous phase and the oil phase so that a coarse emulsion comprising oil droplets least 95% of the oil droplets is less than 5 .mu.m, d. acidifying the emulsion until a pH 3.5 to 4.5 is attained, e. adding, under shear conditions, an aqueous electrolyte solution to the emulsion having a temperature of 10.degree. to 55.degree. C. The electrolyte addition causes flocculation of the emulsion. This flocculation increases the viscosity and imparts an attractive texture to the food dressing.
