COMPARISON OF SOME BIOACTIVE COMPONENTS OF EMMER WHEAT [Triticum dicoccum (SCHRANK) SCHÜBLER] CULTIVARS FROM TWO DIFFERENT ORIGINS GROWN UNDER THE SAME CONDITIONS

Özet

The chemical composition (lipids, fatty acids, proteins, amino acids, starch, dietary fiber, sterols and tocopherols) of two Emmer wheat [Triticum dicoccum (Schrank) Schübler=Triticum dicoccon Schrank] cultivars grown under the same condition in Greece was analyzed. Starch accounted for the highest percentage of the detected substances (67.1-69.4%), followed by proteins (16.1-17.5%) and dietary fiber (ADF 2.1-2.5% and αNDF 5.7-12.0%). The main fatty acids in the lipid fractions (1.36-1.62%) were oleic (35.4-37.0%), palmitic (28.0-31.5%) and linoleic (23.3-28.9%) acids. γ-Tocotrienol (46.1-53.2%), α-tocopherol (28.6-34.4%) and β-tocopherol (15.9-17.8%) predominated in the tocopherol fraction, and β-sitosterol (61.3-67.0%) and campesterol (31.3-37.3%) in the sterol fraction. Arginine (10.8-13.2 g/100 g protein), proline (8.7-13.0 g/100 g protein) and tyrosine (8.3-9.2 g/100 g protein) dominated in the amino acids.
