Abstract
Abstract Improved aqueous edible oil emulsions are obtained by using about 1-20 wt.% of certain water-soluble hydroxy-propylmethyl cellulose ethers as the emulsion stabilizer. These ethers have a thermal gel point of at least 70° C as a 2% aqueous solution, a methoxyl degree of substitution of about 1.12-1.56, a hydroxypropoxyl molar substitution of about 0.10-0.29, and a 2% aqueous solution viscosity of 2-15 cps at 20°C. They are particularly effective in stabilizing homogenized emulsions of citrus flavoring oils used in soft carbonated beverages.
