A comparison of the lipids of triticale, wheat and rye grown under similar ecological conditions

Abstract

Samples of triticale, wheat and rye grown in the same season at the same location in southern United States were analyzed for amounts and types of lipids and for fatty acid composition. Selected kernels of the 3 cereals were separated into anatomical parts (bran, endosperm and germ) and analyzed for amounts and types of lipids, and the anatomical parts of triticale were analyzed for fatty acid composition. The triticale contained several times more phosphatidylcholine and phosphatidylethanolamine than did the wheat and rye. Marked differences in lipid composition were found in the bran, endosperm and germ fractions; and some differences were found among corresponding fractions of the 3 cereals. The bran fractions were rich in steryl esters and contained no glycolipids or phospholipids. Fatty acid compositions of the lipids from the anatomical parts of triticale exhibited some difference. © 1980 American Oil Chemists' Society.
