Abstract
The invention relates to aqueous dispersions containing (a) 5 to 50% by weight of sterols and/or stanols; and (b) 0.5 to 20% by weight of citric acid esters of mono- and/or diglycerides, based on the total weight of the dispersion, wherein the citric acid esters of mono- and/or diglycerides are partially neutralised; and to a process for the production of an aqueous sterol/stanol-containing dispersion, which process comprises (a) dissolving citric acid esters of mono- and/or diglycerides that are partly neutralised, in water; (b) dispersing sterols and/or stanols in the emulsifier solution to form a pre-dispersion; and (c) grinding the pre-dispersion in a ball-mill until the dispersion has a particle mass diameter, d, of less than 5 μm. Optionally, this dispersion is spray-dried.
