title: A new N-nitroso compound, N-2-methylpropyl-N-1-methylacetonyl-nitrosamine, in moldy millet and wheat flour.
abstract: A new N-nitroso compound, N-2-methylpropyl-N-1-methylacetonyl-nitrosamine (MAMPNA), was found in millet and wheat flour inoculated with Fusarium moniliforme Sheldon, a common species of fungi occurring in foods in Linxian County, after 8-day incubation and an addition of a small amount of NaNO2. The compound has been identified by GC-MS and confirmed by synthesized MAMPNA. The present paper reports the isolation and detection of MAMPNA in moldy foods, and discusses the role of the fungus in processes of nitrosamine formation and possible biosynthetic approach of the new compound.
