COLLECTION OF LYSOLECITHIN CONTAINING HIGHLY CONCENTRATED LYSOPHOSPHATIDYLCHLOLINE

PURPOSE:To obtain a lysolecithin containing highly concentrated lysophosphatidylcholine by de-fatting a lysolecithin prepared by treating a lecithin with an enzyme and extracting the lysolecithin with a mixed solvent of CO2 in a liquid state or supercritical state and an alcohol. CONSTITUTION:An ani...

Zusammenfassung:	PURPOSE:To obtain a lysolecithin containing highly concentrated lysophosphatidylcholine by de-fatting a lysolecithin prepared by treating a lecithin with an enzyme and extracting the lysolecithin with a mixed solvent of CO2 in a liquid state or supercritical state and an alcohol. CONSTITUTION:An animal or vegetable derived lecithin is hydrolyzed with an enzyme (usually phospholipase A2) to give a lecithin and fat and oils are extracted from the lecithin with acetone or supercritical carbon dioxide. Then, the lecithin is extracted with a mixed solvent (preferably about 4-20wt.% alcohol) of carbon dioxide in a liquid state or supercritical state and 1-4C alcohol (water content: preferably about 10wt.%), the solvent is removed from the extracted solution to give a lecithin containing highly concentrated lysophosphatidylcholine. When carbon dioxide in a supercritical state is used as the carbon dioxide, the extraction conditions are preferably 40-60 deg.C temperature and 10-30MPa. When liquid carbon dioxide is used as the carbon dioxide, the extraction conditions are preferably -20 to 30 deg.C and 5-8MPa.
