Abstract
In order to analyze the lipid composition ana chemical characteristics of rapeseed oil in relation to content of erucic acid, three recommendable cultivars(MOK-PO 70, MOK-PO DANGYO 12 and 14) seeds were used. The composition of lipid was confirmed by column chromatography and TLC, and the composition of fatty acid in total and neutral lipid was determined by GLC, and the results were as follows. 1. The crude fat was 44.0% to 45.3% in all cultivars. 2. The iodine value, saponification value, acid value and nonsaponifiable content were 100 to 101, 176 to 184, 0.7 to 0.9 and 1.0 to 1.2, respectively, with no remarkable difference among three cultivars. 3. The content of neutral lipid was 95.3% to 96.3% of total lipid, and others were compound lipids. 4. The content to triglyceride was 92. 1% to 92.5% of total lipid. Diglyceride and sterol ester were contained 1.1% and 1.2%, respectively. There was a small quantity of free fatty acid and free sterol and monoglyceride was little. 5. The erucic acid was the highest (26.4%), in MOK-PO DANGYO 12 among the composition of fatty acid, while those of MOK-PO 70 and MOK-PO DANGYO 14 were so small as 1.0% and 3.9%. The content of erucic acid was decreased with the increase of oleic acid, the content of oleic acid in MOK-PO DANGYO 12 was 30%, 63% in MOK-PO 70 and, 60% in MOK-PO DANGYO 14. The content of linoleic acid and linolenic acid showed no remarkable difference but that of eicosenoic acid was 11.7% in MOK-PO DANGYO 12 as the highest. The ratio of the fatty acid content in eluted neutral lipid and the total oil showed no remarkable differences.
