Fatty mono- and di-glycerides are products highly used in the food, cleaning and cosmetic industries because of their emulsifying properties. These products can be obtained through different synthesis routes, namely, glycerolysis of vegetable oils, direct esterification of fatty acids with glycerol or partial transesterification of vegetable oils with alcohols. The last two chemical pathways produce fatty acid esters besides mono/diglycerides, which are difficult to split and purify at industrial scale because of its low vapor pressure, low relative volatility, and high viscosity. In this work, we evaluate the fractionation of fatty acid esters and acylglycerides by supercritical CO2 technology. High pressure experimental extractions were carried out at different operating conditions to validate the technology and a rigorous thermodynamic model was used to evaluate the fractionation process.

The most important acylglycerol chloroderivatives identified in foods are 3-chlorpropane-1,2-diol fatty acid esters (3-CPD esters) that are accompanied by epoxypropanol fatty acid esters formed in processed foods and, particularly, during the deodorisation of vegetable oils. Their content in refined vegetable oils is influenced by the oil composition, refining process conditions and process conditions of hydrogenation. Described and discussed here are the main pathways that lead to the formation of acylglycerols chloroderivatives and epoxypropanol fatty acid esters. The article offers detailed explanation of the reaction mechanisms using the well-known chemical principals based on experimental data. The conditions suitable for removing the unwanted products from the refined vegetable oils were studied in models containing variable proportions of agents (bicarbonates or carbonates) causing the decomposition of 3-CPD fatty acid esters.
