Rapeseed Oil, Superglycerinated Fully Hydrogenated is an emulsifier that is a mixture of monoand diglycerides with triglycer- ides as a minor component. the fatty acid composition is a mixture of saturated fatty acids present in the same proportions as those result- ing from the full hydrogenation of fatty acids in a natural rapeseed oil. it is made by adding excess glycerol to the fully hydrogenated rapeseed oil and heating, in the presence of a sodium hydroxide cata- lyst, to 330°f under partial vacuum and steam sparging agitation. the ingredient is used as an emulsifier in shortenings for cake mixes.
