摘要：In this research; well-known four HPLC methods for patulin analysis were compared in case of repeatability and recovery. The repeatability of these methods was investigated by variation coefficient. In the same apple juice, variation coefficient of parallel patulin findings was found to be changed between 7.2-15.2 %. Different amounts of patulin, 25.8, 514, 77.4 ug/L, for the determination of recovery have been added into apple juice. The average recovery was found to be varied between 73.4-100.5%. The analysis period is 50-140 minute per sample. İSO-8128 was found to be the most suitable between the methods used in this study.
