More Information
Summary:The jasmine oil extracting process includes circular countercurrent leaching of jasmine in leaching machine for 1-3 hr to obtain leached liquid; decompression concentrating the leached liquid to obtain ropy extractum while recovering solvent; extracting the ropy extractum with supercritical CO2 fluid to separate coarse jasmine oil; and rectifying to eliminate water, residual solvent and impurity and obtain refined jasmine oil. The said process has refined jasmine oil yield of 48-55 %.
