Comparison of the proposed method with the literature methods using MIP extraction or clean-up and HPLC-UV analysis for the determination of PAT in apple juice. For comparison, the table summarizes the type of material prepared in each work, the monomers and crosslinkers used for preparation of the MIP part of the final material, the template used for imprinting, the solvent in which the MIP was prepared, the type of analytical procedure used for extraction of PAT, the adsorption capacity of the MIP, and the extraction time associated with the MIP procedure and validation results for LOD, LOQ, and recovery of the final methods. Template, MIP composition, and additional information were not available for commercial materials
