Abstract

PURPOSE:To stably emulsify fats or oils in an aq. soln. or other dispersion medium by dissolving fat, oil, fatty acid, a deriv. thereof or a fat-soluble substance in gas in the super-critical state and carrying out dispersion in the medium. CONSTITUTION:Fat, oil, fatty acid, a deriv. thereof or a fat-soluble substance is dissolved in gas in the super-critical state and dispersed in an aq. soln. or other dispersion medium in a semisolid or solid form to emulsify the fats or oils. For example, the gas contg. the dissolved fats or oils and the dispersion medium are continuously fed into an emulsifying-dispersing device, mechanically emulsified and dispersed, solidified by freezing or cooled under reduced pressure at the outlet of the device and taken out of the device. The solidified or liquefied gas vaporizes and an emulsion contg. the fats or oils emulsified and dispersed in the dispersion medium is continuously obtd. Carbon dioxide is most practically used as the gas in the super-critical state.
