Abstract

Phosphatidylcholine, -inositol and -ethanolamine represented 48, 18 and 8%, respectively, of the total phospholipids in medium and low erucic acid rapeseed. Oleic acid was the principal fatty acid in phosphatidylcholine and -ethanolamine but all components contained high levels of linoleic and saturated acids. There were eight components in the glycolipid fraction of which digalactosyl diglyceride, monogalactosyl diglyceride, sterol glycoside, esterified sterol glucoside and cerebrosides were identified. Defatted flours contained 2.0–3.5% of bound lipid which was composed primarily of phospholipids and glycolipids whereas neutral lipids were also a major component in the bound lipids of protein concentrates. The storage properties of these protein products would be adversely affected by the polyunsaturated fatty acids in these bound fractions.
