Phase equilibria and distribution coefficients of delta-lactones in supercritical carbon dioxide

A static method was used to measure the solubilities and distribution coefficients of delta-lactones (pure), inherent (natural levels) delta-lactones of anhydrous milk fat (AMF) and fortified (added) delta-lactones in AMF in supercritical carbon dioxide (SC-CO2) at 40 degrees C with pressures of 5-3...

Summary:A static method was used to measure the solubilities and distribution coefficients of delta-lactones (pure), inherent (natural levels) delta-lactones of anhydrous milk fat (AMF) and fortified (added) delta-lactones in AMF in supercritical carbon dioxide (SC-CO2) at 40 degrees C with pressures of 5-30 MPa. At 40 degrees C distribution coefficients of delta-lactones increased with pressure and exhibited molecular weight-dependency. Using experimental data, a mathematical model based on thermodynamic equilibria and material balance was developed and used to predict the distribution of inherent delta-lactones of AMF in a continuous SC-CO2 extraction system. At 24.1 MPA/40 degrees C column conditions, AMF was separated into a raffinate and 5 fractions. Predicted delta-lactones distribution coefficients in the raffinate and extract were in good agreement with experimental data
