Abstract
The occurrence of Ochratoxin A (OTA) in wine is commonly known, but there is only limited information about its occurrence in grape mash and wines of German origin. Climate change has led to higher temperatures in the southern regions of Germany, which may increase the growth of fungi associated with the production of OTA and increase the content of this mycotoxin in grapes. A safe and rapid UHPLC-FLD method was developed and validated to assess the contamination of grape mash and wine with OTA. A total of 71 samples of grape mash and 30 wines from various wine producers in Baden-Württemberg, Germany, were analysed for OTA content. The results showed that no samples contained OTA in concentrations above the limit of detection. Further monitoring of samples from different vintages is needed.
众所周知，葡萄酒中含有赭曲霉毒素 A（OTA），但有关其在德国原产葡萄泥和葡萄酒中含量的信息却十分有限。气候变化导致德国南部地区气温升高，这可能会增加与 OTA 生成有关的真菌的生长，并增加葡萄中这种霉菌毒素的含量。为了评估葡萄泥和葡萄酒中的 OTA 污染情况，我们开发并验证了一种安全快速的超高效液相色谱-荧光定量分析方法。对来自德国巴登-符腾堡州不同葡萄酒生产商的 71 份葡萄泥样品和 30 份葡萄酒样品进行了 OTA 含量分析。结果表明，没有样品的 OTA 含量超过检测限。需要对不同年份的样品进行进一步监测。
