CONCLUSIONS<br />
A green process for processing <strong>of</strong> the highly viscous raw lecithin was developed from laboratory scale up to<br />
industrial plant scale. The main advantages using supercritical CO2 instead conventional solvents (which<br />
contaminate lecithin with organic solvents which can not be easily removed) are presented.<br />
Examples on selective extraction and further fractionation <strong>of</strong> components <strong>of</strong> lecithin from raw lecithin are<br />
presented. Fundamentals, like phase equilibrium data for the system oil/SCF as well as mass transfer data will be<br />
given in the presentation. Mechanical design <strong>of</strong> industrial-scale equipment, influence <strong>of</strong> process parameters on<br />
lecithin particle size and particle size distribution, particle shape, modeling <strong>of</strong> extraction procedure <strong>of</strong> the process<br />
will be presented.<br />
