Abstract
With respect to fatty acid composition of lipids, 39 kinds of nonglutinous and 31 kinds of glutinous rice harvested widely in Japan were analyzed by gaschromatography.
It is found that 5 kinds of fatty acid constitute more than 95% of the total acids of the nonglutinous rice; 35-42% of oleic acid, 34-42% of linoleic acid, 15-22% of palmitic acid, 1-2% of linolenic acid and 1-2% of stearic acid. Vector pattern analysis, followed by F-test, indicates that the rice varieties from so-called Koshitsu-mai producing area contain more linoleic acid and less oleic acid than those from so-called Nanshitsu-mai producing area.
Glutinous rice appears to have quite similar fatty acid composition to that of nonglutinous rice except a slightly higher proportion of palmitic acid.
