Molecularly imprinted solid phase extraction for detection of sudan I in food matrices

This study describes the synthesis of a molecularly imprinted polymers (MIPs) for solid phase extraction (MISPE) using Sudan I as template. This procedure allows to concentrate this compound in order to make it detectable by HPLC. Furthermore we investigated the ability of these MISPE cartridges to absorb selectively Sudan I from food matrices. Considerable differences in the interaction with “Sudan I” were observed when MIPs were used as stationary phase in SPE compared with the non imprinted polymers (NIPs).
