2014~2018年黑龙江省小麦和小麦粉中脱氧雪腐镰刀菌烯醇污染水平调查与分析
目的 调查分析黑龙江省小麦和小麦粉中脱氧雪腐镰刀菌烯醇(deoxynivalenol, DON)污染状况。方法 收集黑龙江省90份收购环节小麦和127份市售小麦粉, 样品经乙腈-水(84:16, V/V)溶液浸泡提取, 净化柱净化后, 用液相色谱-串联质谱法对样品中的DON含量进行检测, 并对污染情况进行分析。结果 小麦及小麦粉样品DON平均含量分别为133和417 μg/kg, 检出率均为100%。在检测的217份样品中, 最大检出值为970 μg/kg, DON含量均低于我国限量标准1000 μg/kg。结论 检测数据表明, 小麦和小麦粉易受DON污染; 我国东北部产区小麦粉中DON的含量较中部地区低, 这可能与中部地区的温湿度条件较东北部地区更有利于真菌生长、产毒有关; 小麦粉中DON的含量大于小麦中DON的含量, 提示小麦粉的运输及储存过程可能导致其DON含量增加; 因此, 对市售小麦粉的管理应重点关注其出厂后的运输储存条件。
Objective To investigate and analyze the pollution of deoxynivalenol (Don) in wheat and wheat flour in Heilongjiang province. Methods Totally 90 wheat samples in acquisition period and 127 wheat flour samples from market were collected from Heilongjiang province. Samples were extracted by acetonitrile and water (84:16, V/V) solution, and purified through a solid-phase extraction column. The content of Don was detected by liquid chromatography tandem mass spectrometry. Results The average contents of DON in wheat and wheat flour were 133 and 417 μg/kg, and the detection rate was 100%. Among the 217 samples, the maximum contamination value was 970 μg/kg, and the Don contents of all samples were below the national limit standards 1000 μg/kg. Conclution According to the test data, DON contamination in wheat and wheat flour is common. The content of DON in wheat flour in northeast China is lower than that in central China, which may be related to the temperature and humidity conditions in central China are more conducive to fungal growth and toxin production. The content of DON in wheat flour is higher than that in wheat, which is mainly due to the increase of DON content in wheat flour samples during transportation and storage. The management of wheat flour sold on market should focus on the transportation and storage conditions after leaving the factory.
