<p>Edible fats containing arachidonic acid obtained from microorganisms belonging to the subgenus Mortierella of the genus Mortierella and being capable of producing arachidonic acid, containing little unsaponified matters and, above all, the smallest possible amount of cyclopropane sterols which have never been eaten, and being suitable for the production of foods, in particular, modified milks for infants. The fats contain not more than 0.8 % by weight, preferably not more than 0.6 % by weight of unsaponified matters and 20 % by weight or more of arachidonic acid originating in microorganisms. Further, these fats contain not more than 0.3 % by weight, preferably not more than 0.15 % by weight of 24,25-methylenecholest-5-en-3β-ol. The microorganisms are those belonging to the subgenus Mortierella of the genus Mortierella and being capable of producing arachidonic acid. These microorganisms belong to the species alpina of the genus Mortierella. The foods include modified milks for premature infants, modified milks for infants, foods for infants, and foods for pregnant women and nursing mothers containing the above-mentioned edible fats.</p> |
