将串珠镰刀菌(Fusarium moniliforme Sheldon)接种于玉米面饼上,培养几天之后,加小量NaNO_2,可形成二甲基亚硝胺、二乙基亚硝胺和另外几种尚未确证的亚硝基化合物。其生成量随霉变时间、亚硝化时间和温度、NaNO_2加入量以及玉米品种的不同而改变。这些化合物已用气相色谱火焰离子检定器与氮磷选择性检定器,以及气相色谱—热能分析器初步检出。 Fusarium moniliforme Sheldon was inoculated on corn cake, and after a few days of cultivation, a small amount of NaNO 2 was added to form dimethylnitrosamine, diethylnitrosamine and other unidentified nitroso groups Compound. The amount of its formation with the mildew time, nitrosation time and temperature, the amount of NaNO_2 and maize varieties vary. These compounds have been initially detected using a gas chromatograph flame ionizer, a nitrogen and phosphorus selectivity checker, and a gas chromatograph-thermal analyzer.
