Water-dispersable sterol containing dispersion

摘要

The invention relates to aqueous dispersions containing
a) 5 to 50 % by weight sterols and/or stanols; and
b) 0.5 to 20 % by weight citric acid esters of mono- and diglycerides, based on the total weight of the dispersion 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 diglycerides in water
b) dispersing sterols and/or sterols in the emulsifier solution to form a pre-dispersion
c) grounding the pre-dispersion in a ball-mill until the dispersion has a particle mass diameter d 90 of less than 5 µm. Optionally this dispersion is spray-dried.
