One hundred samples of specially selected spiced meat products (sausages, salami, bologna, wieners, meat loaf, canned luncheon mean, etc) were analysed for nitrate, nitrite and volatile nitrosamines. None of the samples contained high levels of nitrosamines, but many contained traces, generally in the range from 2-50 mug/kg. Some contained as many as four nitrosamines, namely, NDMA, NDEA, NPip and NPy. In a few cases the samples were reanalysed after two weeks' storage at 4 or -20 degrees C, but no significant change in the nitrosamine levels could be detected. The identity of the nitrosamines was confirmed by GLC-high-resolution-MS.
对100份特别挑选的五香肉制品(香肠、意大利腊肠、大红肠、维也纳香肠、肉饼、罐装午餐肉等)进行了硝酸盐、亚硝酸盐和挥发性亚硝胺的分析。没有一个样品含有高含量的亚硝胺,但许多样品含有痕量,一般在2-50微克/千克范围内。有些样品含有多达四种亚硝胺,即N-亚硝基二甲胺(NDMA)、N-亚硝基二乙胺(NDEA)、N-亚硝基哌啶(NPip)和N-亚硝基吡咯烷(NPy)。在少数情况下,样品在4℃或-20℃下储存两周后重新进行分析,但未检测到亚硝胺水平有显著变化。亚硝胺的身份通过气相色谱-高分辨率质谱法得到确认。
