Liquid-liquid equilibrium of systems containing acylglycerols from olive oil, glycerol and isopropanol

Oils enriched with diacylglycerol have received a great deal of attention due to their potential health benefits when used as a replacement for conventional edible oils. This work reports experimental results and thermodynamic modeling of liquid-liquid equilibrium of systems containing mono-, di-and triacylclycerols from olive oil, glycerol and isopropanol. The UNIQUAC model was used in the description of phase equilibria, which was well fitted to experimental data with root mean square deviations equal or lower then 1.4 wt% for the all studies systems. The results presented in this work show the feasibility of diacylglycerol separation from other acylglycerols through liquid-liquid extraction using glycerol and isopropanol as solvents.
