flavour component of many foods. Reaction of AP with nitrite produces two N-nitropyrrole compounds, 1-nitro-2-acetyl-pyrrole (NAP) and 1,3,5-trinitro-2-acetylpyrrole (TNAP), the chemical structures of which have been confirmed by spectral studies, including UV mass, nuclear magnetic resonance, infra-red and elemental analysis (EA). NAP and TNAP are moderately mutagenic to the Salmonella strains TA98
2-乙酰基吡咯(AP)是模型褐变系统的产物,已被分离为许多食品的主要风味成分。AP与亚硝酸盐反应生成两种N-硝基吡咯化合物,1-硝基-2-乙酰基吡咯(NAP)和1,3,5-三硝基-2-乙酰基吡咯(TNAP),其化学结构已通过光谱确认研究包括紫外线质量,核磁共振,红外和元素分析(EA)。在没有哺乳动物激活系统的情况下,NAP和TNAP对沙门氏菌TA98和TA100菌株具有中等致突变性,并且对小鼠C3H10T1 / 2细胞具有明显的细胞毒性。这些结果表明,硝基衍生物的直接作用诱变剂的形成可以在含亚硝酸盐的食物中或在体内通过摄入AP进行亚硝化而形成。
