The most important acylglycerol chloroderivatives identified in foods are 3-chlorpropane-1,2-diol fatty acid esters (3-CPD esters). They 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 acylglycerol chloroderivatives and epoxypropanol fatty acid esters. The article offers detailed explanation of the reaction mechanisms using the well-known chemical principles 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.
