Claims15
A method for preparing a sterol and/or stanol fatty acid ester composition, wherein less than 7% of the fatty acid moieties comprises saturated fatty acids and more than 50% comprises polyunsaturated fatty acids, comprising
- a) esterifying a sterol and/or stanol with an excessive amount of high PUFA alcohol ester in the presence of an interesteritication catalyst and
- b) fractionating the sterol and/or stanol fatty acid ester in the high PUFA alcohol ester to obtain the defined fatty acid ester composition.
A method for preparing an edible oil or fat blend with elevated sterol and/or stanol content comprising a sterol and/or stanol fatty acid ester composition, wherein less than 7% of the fatty acid moieties comprises saturated fatty acids and more than 50% comprises polyunsaturated fatty acids, comprising
- a) esterifying a sterol and/or sterol with an excessive amount of high PUFA alcohol ester in the presence of an interesterification catalyst
- b) fractionating the sterol and/or stanol fatty acid ester in the high PUFA alcohol ester to obtain the defined fatty acid ester composition and
- c) mixing the sterol and/or stanol fatty acid ester with a vegetable oil or a fat blend.
A method for preparing an edible oil or fat blend with elevated sterol and/or stanol content comprising a sterol and/or stanol fatty acid ester composition, wherein less than 7% of the fatty acid moieties comprises saturated fatty acids and more than 50% comprises polyunsaturated fatty acids, comprising
- a) interesterifying a sterol and/or stanol and an edible oil with an excessive amount of high PUFA alcohol ester in the presence of an interesterification catalyst and
- b) fractionating the sterol and/or stanol fatty acid ester to obtain the composition.
