Abstract
Favorable characteristics and confronting problems in developing the modern application of fish oil are reviewed.
In order to expand the utilization of fish oil, daily and highly consumed linoleic acid and saturated fatty acids must be replaced in part by icosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) concentrated fish oil, keeping the total lipid consumption at the level of modern Japan.
For this purpose, technology in modifying lipids including enzymatic synthesis of EPA and DHA rich simple lipids as well as phospholipids is considered to be impelled.
