脱氧雪腐镰刀菌烯醇（DON）是毒性最小的一种，然而，它是人类食物中最常见的一种雪腐镰刀菌烯，它的存在是其他毒性更大的雪腐镰刀菌烯可能发生的一个指标。本研究的目的是探讨真菌植物群沿着DON浓度在从吉达市场收集的小麦样品中，这植物群和检测到的DON之间的相关性。从吉达市场收集全粒小麦样品，这代表进口和当地生产的小麦。本研究结果表明，大肠杆菌的发病率较高。样品的高效液相色谱（HPLC）色谱图显示出较高的DON分辨率。尽管在这些样本中没有检测到镰孢菌属物种，但在收集的样本中检测到的DON浓度范围为15至800 μg/kg。部分进口样品中DON含量超过200 μg/kg（婴儿食品和幼儿食品的安全限值）的50%。这些样品中存在某些致真菌性真菌，应设置这些样品在储存期间可能被其他真菌毒素污染的警报。然而，根据欧盟委员会的规定，所有小麦样品中的DON水平均在未加工小麦中DON的允许水平（1750 μg/kg）范围内。关键词：真菌区系，真菌毒素，脱氧雪腐镰刀菌烯醇（DON），小麦，吉达，沙特阿拉伯
Deoxynivalenol (DON) is one of the least toxic trichothecenes, however, it is the most prevalent trichothecenes in human foods and its presence is an indicator of the possible incidence of other more toxic trichothecenes. This study aimed to explore the fungal flora along with the DON concentration in the collected wheat samples from Jeddah market to correlate between this flora and the detected DON. Whole grain wheat samples were collected from Jeddah market and this represents imported and locally produced wheat. The results indicated in this study showed high incidence of Aspergilli . The high-performance liquid chromatography (HPLC) chromatogram of the samples showed high DON resolution. DON was detected in a range of 15 to 800 μg/kg in the collected samples although no Fusarium species was detected in these samples. The 200 μg/kg DON level (the safe limit for baby foods and young children) was exceeded by 50% of some of the imported samples. The presence of some toxigenic fungi in these samples should set the alarm of possible contamination of these samples with other mycotoxins during storage. However, the level of DON in all wheat samples was within the permissible level of DON in unprocessed wheat which is 1750 μg/kg according to the European Commission.
