DESCRIPTION

Rapeseed Oil, Superglycerinated, occurs as a white solid. It is a mixture of mono-, di-, and triglycerides, with triglycerides as a minor component. The saturated fatty acids are found in the same proportions that result from the full hydrogenation of fatty acids occurring in natural high-erucic acid rapeseed oil. The rapeseed oil is typically obtained by n-hexane extraction from Brassica juncea, Brassica napus, and Brassica rapa (Fam. Cruciferae). It is made by adding excess glycerin to fully hydrogenated rapeseed oil and heating to about 165° in the presence of a sodium hydroxide catalyst under partial vacuum and steam sparging agitation.
