Analysis of patulin in apple products by liquid-liquid extraction, solid phase extraction and matrix solid-phase dispersion methods: a comparative study

Patulin is a marker of quality in the apple and apple juice industry and due to the potential risk for human health, reliable and potential methods for extracting patulin from a sample are therefore needed. In this study, the three methods with liquid-liquid extraction, matrix solid-phase dispersion (MSPD) and with solid-phase extraction (SPE) were studied for extracting patulin from different apple products. Result showed that for AJC and apple sample, MSPD method is most suitable for extracting patulin among the three methods. The recovery rates of AJC and apple sample were 80.35-114.46 and 79.68-94.32%, respectively, the coefficient variations were 3.18-4.90%; For dilute juice, SPE procedure is suitable for analysis of patulin and the recovery rates were and 85.35-90.14%.
