“…This latter observation can be explained by the higher chlorine content of sediment‐rich fractions, as reported earlier. [ 31 ] Beyond confirming that increased acidity may lead to excessive boost in the formation of MCPD, these results also imply that in order to mitigate the formation of MCPD originating from the crude oil, the removal of trace sediments is more critical for highly acidic oil samples than for less acidic ones. Further, these results also represent a possible explanation why the same efficacy of sediment removal can result still in oils with different MCPD levels simply due to their different acidity.…”

“…The residual sediments of crude vegetable oils have been reported to be a potential source for the formation of MCPDE. [ 31 ] However, the compatibility, technical feasibility, and interplay between removing the sediments and other refining steps such as degumming, bleaching, and deodorization are currently not known. Accordingly, in this work we explored how the MCPD mitigation benefit of removing these residual sediments is impacted when the process is integrated into a full physical refining including degumming, bleaching, and deodorization.…”

“…It has been reported that beyond phospholipids, the sunflower oil, [42,43] and its precipitated fraction [30] also contain waxes. Accordingly, the sunflower oil samples used in this study and the palm oil samples spiked with the aqueous gum phases obtained from sunflower oil, also contained waxes, see Table S1 in the Supporting Information.…”

“…[29] There is accumulating evidence, that the upfront purification of the crude oil from residual sediments and trace chlorine carriers can be beneficial in preventing the formation of MCPD. [27,30] In this regard, the composition of the sediment indicates that the phospholipid fraction correlates with the chlorine content. Furthermore, recent trials attempting to trap the chlorine carriers suggest that amphiphilic substances likely have a direct or indirect chlorine trapping capability, which may be leveraged for MCPD mitigation purposes.…”
