Title:
METHOD OF PURIFYING CRUDE XANTHOPHYLLS
Document Type and Number:
WIPO Patent Application WO/2002/059341
Kind Code:
A1
Abstract:
A method of purifying crude xanthophylls characterized by comprising treating the crude xanthophylls, which are obtained by extracting algae with a solvent, with a lipase in the presence of water under acidic conditions without controlling the pH value at a temperature of 4 to 90°C to thereby selectively hydrolyze contaminating neutral lipids (mono-, di- and triglycerides), subjecting the lipase-treated liquor to oil/water separation, and then eliminating free fatty acids from the oily layer thus fractionated to thereby elevate the content of xanthophylls.
