Abstract
The chemical components of barley (Jinmichapssal, Seodunchal, and Dusan No.8) and wheat (Alchanmil, Tapdongmil, and Olgeurumil) varieties were determined in terms of proximate compositions, minerals, fatty acids, amino acids and vitamin. There are significant differences in protein and lipid (p<0.00l, respectively), fiber (p<0.05) of barleys. There are significant differences in lipid contents (p<0.00l) of wheats. The major minerals of barley were Ca 24∼31 mg%, P 117∼129 mg%, Fe 1.7∼2.9 mg%, Na 13∼18 mg%, K 227∼73 mg%, Zn 1.1∼1.2 mg%, and Mg 38∼45 mg%. The content of Ca in Jinmichapssal was significantly higher than those in the other varieties (p<0.00l). The mineral contents of wheat were Ca 39∼67 mg%, P 172∼270 mg%, Fe 3.7∼5.6 mg%, Na 15∼17 mg%, K 537∼558 mg%, Zn 2.1∼2.3 mg% and Mg 106∼127 mg%. There are significant differences in Ca, P, Fe and Mg of 3 kinds of wheat. The barleys contain vitamin B$_1$ 0.27∼0.36 mg%, vitamin B$_2$ 0.07∼0.11 mg% and niacin 1.21∼1.44 mg%. The content of vitamin B$_1$ in Jinmichapssal and Seodunchal was significantly higher than that in Dusan No.8 (p<0.0l). The content of vitamin B$_2$ in Seodunchal (0.11 mg%) was significantly higher than those in the other varieties (p<0.0l). The content of niacin in barleys was no significant differences. The wheats contain vitamin B$_1$ 0.41∼0.52 mg%, vitamin B$_2$ 0.29∼0.39 mg% and niacin 1.86∼2.81 mg%. The contents of vitamin B$_2$ in Olgeurumil (0.39 mg%) and niacin in Tapdongmil (2.81 mg%) were considerably higher than those in the other varieties. The contents of vitamin B$_1$, B$_2$, niacin in wheats were higher than those of barleys. Major fatty acids in barley and wheat varieties were linoleic acid, palmitic acid and oleic acid, which comprised of about 90%∼92% of total fatty acid. The contents of lysine, valine, and tryptophan in Dusan No.8 were significantly higher than those in the other varieties. The contents of lysine, isoleucine in Tapdongmil were significantly lower than those in the other varieties. The content of amino acid in wheat was higher than those of barleys.
