Abstract
The invention relates to a method for the production of highly stable aqueous dispersions of phytosterols, phytostanols and derivatives thereof, which allows the use of a wide range of emulsifiers in relatively small concentrations in relation to the phytosterols and which allows the preparation of dispersions with high concentrations of phytosterols. Said dispersions are obtained using a method in which one or more phytosterols, an aqueous medium and one or more emulsifiers are dispersed in a disperser at a temperature of at least 140° C. in order to obtain an emulsion and the resulting emulsion is subsequently cooled in order to obtain a dispersion of sterols in an aqueous medium.
Claims9
A process for the production of an aqueous dispersion of one or more phytosterols comprising the steps of:
- a) adding each of the following components to a heated disperser in a single step:
- one or more phytosterols, 5 mg to less than 10 mg of one or more sodium or potassium salt of an organic acid per gram of phytosterols, the organic acid having from 10 to 24 carbon atoms, and water;
- and then dispersing the mixture at a temperature in the range of 150° C. to 200° C. to produce an aqueous emulsion of phytosterol or phytosterols;
- and
- b) cooling the emulsion to produce an aqueous dispersion of phytosterol or phytosterols;
- provided that the sodium or potassium salt of an organic acid having from 10 to 24 carbon atoms is not sodium stearoyl lactylate.
