Studies on fatty acid composition of fixed oil extracted from canola and rapeseeds for erucic acid content

摘要

The fixed oils from the seeds of canola and rape plants (N.O. Crucifeae) have been characterized and studied for their fatty acid composition by GLC. The two oils were compared and it was found that mustard oil (rape seed oil) samples contained 41.5-45.7% erucic acid other than palmitic acid (1.8-4%), stearic acid (0.34-11%), oleic acid (15.6-24.3%), linoleic acid (12.0-13.7%), linolenic acid (1.9-2.1%), arachidic acid (2.0-2.9%) and lignoceric acid (4-4.7%). The canola oil contained only 0.0-1.7% erucic acid other than myristic acid (0.1-0.4%), palmitic acid (5.5-11.5%), stearic acid (1.6-3.7%),oleic acid (48.9-60.6%), linoleic acid (3.7-26.8%), linolenic acid (6.4-9.7%), arachidic acid (2.0-2.9%), and behenic acid (0.34-0.81%).
