Title:
METHOD FOR PURIFYING CRUDE XANTHOPHYLL
Document Type and Number:
Japanese Patent JP2002218994
Kind Code:
A
Abstract:
To provide a new method for the purification of crude xanthophylls.
Crude xanthophyll obtained by the solvent extraction of algae is purified by treating the xanthophyll with lipase in the presence of water under acidic condition at 4-90°C without adjusting the pH to effect the selective hydrolysis of neutral lipids (mono, di or triglyceride) existing as foreign materials, separating the lipase-treated liquid into oil and water and separating free fatty acids from the obtained oil layer.
