Extracting method of functional lipid using supercritical fluid and Manufacturing method of hydrogel containing the functional lipid

摘要

The present invention is a step of degreasing neutral lipids from vegetable oil by supercritical treatment using a supercritical fluid, and dissolving functional lipids to be extracted from the vegetable oil in the organic solvent by adding an organic solvent to the degreased vegetable oil. And selectively extracting only the solution in which the functional lipid is dissolved to obtain an extract, and concentrating the extract in which the functional lipid is dissolved to obtain a functional lipid concentrate, and extracting the functional lipid using a supercritical fluid. A hydrogel containing functional lipids. According to the present invention, high purity and high concentration of functional lipids can be efficiently extracted from vegetable oils using supercritical fluid for discarding or feed.;Functional lipids, sphingolipids, phospholipids, supercritical fluids, vegetable oils, hydrogels
