摘要
A high performance liquid chromatography with a diode-array detector (HPLC-DAD) and a gas chromatography with a mass spectrometer (GC-MSD) are described for the determination of patulin (PAT) in apple juice. The limits of detection (DL) and quantification (QL) for the HPLC-DAD and GC-MSD method were found to be (DL = 0.23 μg kg−1 QL = 1.2 μg kg−1) and (DL = 5.8 μg kg−1 and QL = 13.8 μg kg−1), respectively. The recovery factors for HPLC-DAD and GC-MSD were found to be 99.5%(RSD%= 0.73) and 41%(RSD%= 10.03), respectively. The HPLC-DAD method was used to determine the occurrence of PAT in 90 samples of fruit juices.
