Title: Water-in-oil dispersion and process for preparing such dispersion
Inventor: NORTON IAN TIMOTHY
IPC: C09K23/00
Filed: 1990-05-14
Granted: 1997-01-14
Abstract: The present invention is concerned with a process for preparing a dispersion comprising a continuous fat phase and a dispersed gelled aqueous phase, wherein a water-continuous composition, containing at least 1% gelatin by weight of water, is cooled from above the gel setting temperature of the water-continuous composition to below said gel setting temperature and subjected to such conditions of shear that the water-continuous composition is converted into small gelled aqueous beads, after which a fat-continuous dispersion is formed while maintaining the temperature at below the gel melting temperature.    The process according to the invention offers the advantage that it enables the preparation of water-in-oil dispersions of extremely low fat content even when using aqueous phase compositions which in the ungelled state do not possess a high viscosity. Also the present process makes it possible to incorporate ingredients into the aqueous phase which, in the absence of a gelled structure, would promote and actually induce the formation of an oil-in-water dispersion.     Another aspect of the present invention is a dispersion comprising less than 23% by weight of a continuous fat phase and a dispersed gelled aqueous phase containing gelatin at a concentration of 1 to 7 times its critical concentration and optionally a combination of one or more gelling agents other than gelatin at a concentration below their critical concentration.
