中文摘要：本研究采集了134个样品，包括58个小麦、40个方便面和36个饼干，分析脱氧雪腐镰刀菌烯醇（DON）存在情况。这些样品于2010-2014年间，从圣保罗市的零售市场获得。用高效液相色谱-紫外检测法检测DON并进行免疫亲和净化。方法验证遵循国际准则。考虑到样品的不同型态，LOD 和LOQ分别为60 和200 mu gkg(-1)。本研究发现的最低回收率出现在方便面样品中，其中，最低回收率为91.8%，RSD为 4.5%，。面粉、方便面和饼干中DON检出率分别为91.4%、97.5%和97.2%，总检出率为94.8%，含量从LOD到1720.00 mu gkg(-1)。
外文摘要：A total of 134 samples, consisting of 58 wheat flour, 40 instant noodle and 36 biscuits, were analysed for the presence of deoxynivalenol (DON). The samples were obtained from retail markets of the city of São Paulo during the period 2010–2014. DON was determined by high performance liquid chromatography with ultraviolet detection and immunoaffinity sample clean-up. Method validation followed international guidelines. The LOD and LOQ were 60 and 200 µg kg−1, respectively, considering the three different types of samples analysed. The lowest recovery found in this study was 91.8% with RSD 4.5% for instant noodles. DON was detected in 91.4%, 97.5% and 97.2% of samples wheat flour, instant noodles and biscuits, respectively, resulting in a total of 94.8% with levels ranging from LOD to 1720.0 µg kg−1.
