Formation of 3-MCPD esters has a positive correlation with MAGs, DAGs and chlorine.
Chlorine is more predominant than acylglycerols in terms of precursors.
Washing bleached oil can reduce the 3-MCPD esters in deodorized oil.
Adding diacetin can mitigate the formation of 3-MCPD esters during deodorizing.
