Stanol composition and the use thereof
A stanol composition containing in addition to sitostanol as the main component, also a substantial amount of at least 10% campestanol has been found to effectively lower serum cholesterol levels when incorporated in edible commodities. Upon esterification the composition is especially useful in edible fats and oils and in fat-containing foods.
1. A method of lowering blood serum campesterol level in a human subject, comprising administering to the subject an effective amount of a composition comprising a stanol fatty acid ester mixture, wherein the stanol fatty acid ester mixture comprises sitostanol fatty acid esters and campestanol fatty acid esters, wherein the campestanol fatty acid esters are present in an amount of 20 to 40 weight % of the stanol fatty acid ester mixture.
2. The method of claim 1 , wherein the campestanol fatty acid esters are present in an amount of 25 to 35 weight % of the stanol fatty acid ester mixture.
3. The method of claim 1 , wherein the campestanol fatty acid esters are present in an amount of about 30 weight % of the stanol fatty acid ester mixture.
4. The method of claim 1 , wherein the stanol fatty acid ester mixture is derived from plant sterols.
5. The method of claim 4 , wherein the stanol fatty acid ester mixture is derived from vegetable oil sterols.
6. The method of claim 5 , wherein the stanol fatty acid ester mixture is derived from corn, soybean or rapeseed sterols.
7. The method of claim 1 , wherein the stanol fatty acid ester mixture is administered at a daily dose of about 3 grams per day.
8. The method of claim 1 , wherein the sitostanol fatty acid esters and the campestanol fatty acid esters are synthetically produced.
9. The method of claim 1 , wherein the sitostanol fatty acid esters and the campestanol fatty acid esters are prepared by a method comprising the step of esterifying free sitostanol and free campestanol.
10. The method of claim 1 , wherein the stanol fatty acid ester mixture is administered orally.
11. The method of claim 1 , wherein the stanol fatty acid ester mixture is administered as a component of a food composition.
12. The method according to claim 1 , wherein the method further lowers serum cholesterol levels.
