Disclosed is a method for reducing the sterol for example cholesterol, content of sterol-containing substances such as fats and oils. The method provides an efficient and cost effective process based on the phospholipid bilayers. Phospholipid aggregates are contacted with for example, a sterol-, containing fat or oil in an aqueous environment and then mixed. Following adequate mixing, the sterol-reduced fat or oil is separated from the aqueous separation mixture as shown in the figure. Alternatively the corresponding , sterol-enriched phospholipid also may be isolated from the aqueous separation mixture.

Why it's free to use
- Filed January 14, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 14, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 14, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
