Title:
METHOD FOR PRODUCTION OF CONDENSED POLYUNSATURATED FATTY ACID OIL
Document Type and Number:
WIPO Patent Application WO/2007/119811
Kind Code:
A1
Abstract:
Disclosed is a method for production of a condensed PUFA oil, which comprises performing an alcoholysis reaction of a PUFA-containing oil-and-fat with a lipase in the presence of at least one compound selected from magnesium oxide, magnesium hydroxide, calcium oxide and calcium hydroxide and a small quantity of water and separating a glyceride fraction.
