Abstract
Quick and simple analytical methodology has been developed for the measurement of patulin in apple juice by combining single-drop liquid-liquid-liquid microextraction with isotope dilution ultra-high performance liquid chromatography-mass spectrometry. After systematic parameters optimization, the whole sample pretreatment only consisted of single extraction that consumed 1.5â¯mL ethyl acetate. While, other methods usually needed complicated pretreatment, including extraction, purification, evaporation and redissolution. This sample pretreatment method could greatly lower the interferences from sugar-rich matrix, and the limit of detection was 0.5â¯Î¼g/L and limit of quantification was 2â¯Î¼g/L in apple juice. Moreover, linear range covered three orders of magnitude from 2 to 2000â¯Î¼g/L. The proposed method is promising for patulin extraction and detection in apple juice, which will opens a new perspective in the enrichment of trace contaminations in high sugar complex matrix.
