Effect of Various Treatment Methods on the Bisphenol A Concentration in Edible Mushroom Segments during Cultivation

The aim of study were to analyzed bisphenol A (BPA) concentrations in Polyvinyl Chloride (PVC) bottles used for cultivation of edible mushrooms, cultivation materials and fruiting bodies of Pleurotus eryngii with various treatments by HPLC-MS. BPA was detected in bottles, cultivation materials and fruiting bodies at levels greater than the limit of detection (0.000611 μg/g). BPA levels decreased from 19.851 to 6.230 μg/g following exposure to high temperature and pressure. In addition, the mean BPA levels increased in a pH-dependent manner to 11.37-30.80 μg/g. With the exception of those grown in new bottles, fruiting bodies contained BPA at levels not exceeding the recently established specific migration limits of 0.6 mg/kg for food established by the European Union. These data suggest that physical treatment methods could decrease BPA levels in new PVC bottles. Use of such treatments rendered fruiting bodies of P. eryngii safe for consumption.
