Abstract
- Background: Palm oil is the most consumed worldwide, being evident its importance due to several applications by the food industry. The presence of toxic and mutagenic compounds, such as chloropropanols and glycidyl fatty acid esters has increased the attention on this oil. Very recently, there have been several alerts about the safety of certain foods containing palm oil in their composition. Consequently, the European Commission has demanded the evaluation of these hazardous compounds in several food matrices, including palm oil, turning this issue into a public health concern. Scope and approach: This review focuses on chloropropanols and glycidyl fatty acid esters in palm oil, their precursors, occurrence and mitigation strategies, as well as scientific opinions, current legislation and analytical approaches. Key findings and conclusions: Liquid chromatography coupled to mass spectrometry detection is preferred in the analysis of chloropropanols and glycidyl esters in palm oil. Concerning the precursors, the presence of chlorides and mono- and diglycerides is related to high amounts of these compounds, especially glycidyl esters. Several differences in the occurrence of these compounds in palm oil were reported, namely in what concerns to applied processing (refining/deodorization conditions; temperature/time of frying in the presence or absence of food). There is still much work to be done to implement efficient mitigation strategies without compromising the safety of palm oil. Furthermore, regarding the maximum levels in foodstuffs, European Commission is finalising the new EU legislation which will include values for the maximum levels of glycidyl fatty acid esters in vegetable oils. Highlights: Removal of critical reactants from palm fruit or seeds decreases 3-MCPD and GEs; Chlorides and acylglycerols are precursors, but more studies are needed; Adequate deodorization temperature decreases 3-MCPD and GEs in palm oil; Frying temperature seems to have a minor impact in GEs formation; Mitigation strategies which do not affect the safety of the oil are required.
