Article Synopsis
- A new method was developed to measure 21 different polychlorinated biphenyl (PCB) metabolites in animal-based foods using a green solvent technique called deep eutectic solvent (DES) based microextraction combined with advanced gas chromatography.
- The method optimized important parameters like the type and amount of DES used, achieving effective results with detection limits as low as 0.12 ng/mL and recovery rates between 80.1-111.4%.
- Applied to real-world samples (like milk, meat, fish, and eggs), the analysis found PCB metabolite levels ranging from 0.64 to 32.14 ng/g, marking a significant advancement in routine food safety testing.
A new dummy template-based molecularly imprinted dispersive micro solid-phase extraction (MI-d-µSPE) coupled with HPLC-FLD developed for the simultaneous determination of four aflatoxins (B, B, G, G) in various food matrices. The synthesized MIP was used as a dispersive solid-phase extraction (dSPE) sorbent for aflatoxins extraction. The chemometric approach was used to identify the optimum conditions of dSPE.

Further, the influential parameters pH, vortex time, and volume of NIHDES for extraction of 13 BPs were optimized by employing the design of experiment. The LOQ and recoveries were observed to be 0.
