Method for Manufacturing Fat-soluble Ester Compound of Phytosterol or Phytostanol Unsaturated Fatty Acid for Lowering Cholesterol Level

摘要

The invention as well as the treatment of cholesterol hyperplasia, will in some heart disease and liquid five days available to the prevention of high blood pressure relates to a process for the preparation and a functional food containing them in an unsaturated fatty acid ester compounds are soluble phytosterol or phyto stanol. Obtained in the present invention, the step of dissolving the phytosterol or phyto stanol and an unsaturated fatty acid in a non-polar organic solvent and then adding a basic catalyst, adding an carboxyl activating substance soluble in non-polar organic solvent in the esterification reaction, and electric step after removal under reduced pressure of the solvent from the reaction product, stirring was added a methanol or a methanol / acetone mixed solvent, and provides a method for producing unsaturated fatty acid ester compounds are soluble phytosterol or phyto stanol in the liquid oil, which comprises the step of precipitation. In the present invention, an unsaturated fatty acid ester of a phytosterol or phyto stanol made by the method of electrical as well as to be easily dissolved in the liquid oils, such as oil or phytosterol existing pitot star Unlike play corn, LDL- cholesterol harmful to the human body reduce the absorption of cholesterol, while lowering the value, the absorption of HDL- cholesterol has been found that it does not affect. Thus, the unsaturated fatty acid ester compounds are soluble phytosterol or phyto stanol in the liquid five days produced according to the present invention, as well as the treatment of cholesterol hyperplasia, widely in some heart disease and the active ingredient in the food that can be used in the prevention of high blood pressure It may be applied.
