The procedure applied in this work was performed according to
the paper published by Kuhlmann (2011). Originally the methodology
was dedicated for determination of bound 3-MCPD and
bound glicydol in refined oils. According to the available literature
data this so called SGS “3-in-1” method provides accurate measurement
avoiding underestimation of the analytes concentration.
The mild alkaline transesterification minimizes the possibility of
MCPD transformation into glycidol. In this study, only the concentration
of MCPD esters was examined.
