In this study, ten toxins were analysed in wheat and maize commodities from Albania. In total, 71 samples of wheat and 45 samples of maize were collected from different producing regions. The analytical procedure consisted of a simple one-step sample extraction followed by the determination of toxins using liquid chromatography coupled with tandem mass spectrometry. toxins were found in 23% of the analysed wheat samples and in 78% of maize samples. In maize samples, most often fumonisins B (FB1) and B (FB2) were found. They were present in 76% of samples. They were detected in all positive samples except in one with concentrations ranging from 59.9 to 16,970 μg/kg. The sum of FB1 and FB2 exceeded the EU maximum permitted level (4000 μg/kg) in 31% of maize samples. In wheat samples, the only detected mycotoxin was deoxynivalenol (DON), present in 23% of samples. In one sample with the concentration of 1916 μg/kg, the EU maximum permitted level (1250 μg/kg) was exceeded. This is the first report on the presence of toxins in wheat and maize grains cultivated in Albania.
本研究分析了来自阿尔巴尼亚的小麦和玉米商品中的十种真菌毒素。总共采集了来自不同产区的 71 份小麦样本和 45 份玉米样本。分析程序包括简单的一步样品提取，然后使用液相色谱-串联质谱法测定毒素。在 23%的小麦样本和 78%的玉米样本中发现了真菌毒素。在玉米样本中，最常发现的是伏马菌素 B（FB1）和 B（FB2）。它们存在于 76%的样本中。除了一个样本浓度在 59.9 到 16970μg/kg 之间外，所有阳性样本中都检测到了它们。FB1 和 FB2 的总和在 31%的玉米样本中超过了欧盟允许的最大限量（4000μg/kg）。在小麦样本中，唯一检测到的真菌毒素是脱氧雪腐镰刀菌烯醇（DON），存在于 23%的样本中。在一个浓度为 1916μg/kg 的样本中，超过了欧盟允许的最大限量（1250μg/kg）。这是关于在阿尔巴尼亚种植的小麦和玉米谷物中存在真菌毒素的首次报告。
