Studies on the Chemical Composition of Korean Cruciferal Seed

Abstract

For the effective utilization of Korean Crnciferal seeds, the chemiacl characteristics, lipid compostion and amino acid composition were analysed in six kinds. The content of crude lipid was 39. 1% to 46. 5% in Korean Cruciferal seeds. The iodine value, saponification value and acid value were 93.4 to 107. 2, 170.4 to 185.0 and 0. 7 to 1. 2 in Cruciferal seed oils, respectively. The content of neutral lipids was 9:1. 3% to 96.4% to total lipid, while that of compound lipids was 3. 6% to 4. 2%. The content of erucic acid was 33. 4% to 51. 5 % to total fatty acid in Gerg-gac, Chin-ju Daepung, Seoul-cabbage, and that of Mok-po 71 was only 0. 8%. The content of erucic acid was decreased with increasing amount of oleic acid, Among the amino acid in defatted seed meals, glutamic acid, leucine, lysine, arginine and proline showed high quantity and the sum of these amino acids occupied 50% to total amino acid. While cystine and methionine were poor in content.
