High-oleic-acid rapeseed oil as starting material for the production of confectionary fats via lipase-catalyzed transesterification

• Lipase-catalyzed transesterification of high-oleic-acid rapeseed oil with stearic acid or methyl stearate was investigated. High yields of 1,3-distearoyl-2-monooleyl glycerol (36%) and 1(3)-2-dioleyl-1(3)-monostearoyl glycerol (27%) with small incorporation of stearic acid in the 2-position were obtained by using lipase from Rhizopus arrhizus immobilized on polypropylene powder and ethyl stearate as acyl donor.
