ARACHIDONIC ACID-CONTAINING EDIBLE FATS AND OILS AND FOOD CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain arachidolic acid-contg. edible fats and oils which are the arachidolic acid-contg. edible fats and oils obtainable from the microorganisms belonging to the Mortierella subgenus of Mortierella genus having arachidolic acid producibility, are low in the content of unsaponifiable materials, do not contain sterol having the cyclopropane ring having no dietary experience in particular among these materials as far as possible and are particularly suitable for production of prepd. milk for infants. ;SOLUTION: The arachidolic acid-contg. edible fats and oils have ≤0.8wt.%, more preferably ≤0.6wt.% unsaponifiable material content and ≥20wt.% arachidolic acid content and are derived from the microorganisms. The edible fats and oils are ≤0.3wt.%, more preferably ≤0.15wt.% 24,25- methylenecholesto-5-en-3β-ol. The microorganisms are the microorganisms belonging to the Mortierella subgenus of Mortierella genus having productive ability of the arachidolic acid. The microorganisms belonging to the Mortierella subgenus are the microorganisms belonging to the Mortierella genus Alpine species.;COPYRIGHT: (C)1998,JPO
