Enzymatic modification of vegetable oil with an active membrane plus supercritical carbon dioxide
Membranes with specific enzymatic activities and low pore sizes (a few nanometers) have been recently developed at the European Membrane Institute. They represent "natural" assemblies of multiple microreactors placed in parallel, on which it is easy to favour the meeting between substrates -that one can force to cross the pores using the transmembane pressure- and catalyst -deposited onto the surface of material-. One can thus optimise the performance of reactions, as demonstrated with various low viscosity solvents (water, organic or even supercritical CO2 solutions). With highly viscous liquids such as oils, classical filtration is much more difficult. In this work the idea to decrease oil viscosity by injecting supercritical CO2 following a technique recently developed by the French Nuclear Commission, and then to modify oil characteristics through an active membrane, has been tested. The interesterification between castor oil triglycerides (TG) and methyl oleate, using a lipase as catalyst, in the presence of SC CO2 has been chosen as model system. A specific analytic method has been set up which uses planar chromatography for product separation, and clearly shows disappearance of methyl oleate as well as formation of methyl ricinoleate. The first experimental results make it possible to validate the new concept and show that the technology opens very interesting prospects for the biotransformation of biological products with a high viscosity.
