Public interest in nitrate and nitrite content reduction in meat products has increased; therefore, the aim of the present study was to determine nitrate and nitrite levels in commercial meat products as the main source of added nitrites, and to estimate their dietary intake by children. The intake of nitrite from processed meat products and drinking water by Estonian children was estimated. Daily intake estimations were based on the food consumption data of the National Institute for Health Development. In addition, nitrite/nitrate concentrations of meat and processed meat products were measured using a liquid chromatographic method with UV detection. Mean nitrite intakes among 1087 studied children were 0.015 and 0.016 mg kg b.w. day, respectively, among children aged 12-35 months and 3-10 years. Acceptable daily intake (ADI) of 0.07 mg nitrite kg b.w. day was exceeded in 3.1% of children, being more prevalent in the younger age group. Considering the consumption of processed meat and drinking water, mean nitrite intakes in the younger and the older age groups were, respectively, 21.9% and 22.9% of the ADI. Study results indicated that over a period of 10 years, children's dietary nitrite intake from processed meat products has declined, which is probably caused by changes in food preferences and decreased usage of nitrite in cured meat products by meat industries.
公众对减少肉制品中硝酸盐和亚硝酸盐含量的兴趣日益浓厚；因此，本研究旨在测定商业肉制品中亚硝酸盐和硝酸盐的含量，因为这些肉制品是添加亚硝酸盐的主要来源，并估计儿童的饮食摄入量。估算了爱沙尼亚儿童从加工肉制品和饮用水中摄入的亚硝酸盐量。每日摄入量估计是基于国家健康发展研究所的食物消费数据。此外，使用带有紫外检测的液相色谱法测量了肉类和加工肉类产品中亚硝酸盐/硝酸盐的浓度。在 1087 名研究儿童中，12-35 个月和 3-10 岁儿童的平均亚硝酸盐摄入量分别为 0.015 和 0.016 mg/kg bw/day。有 3.1%的儿童超过了 0.07mg 亚硝酸盐/kg bw/day 的日允许摄入量（ADI），且这一比例在年龄较小的儿童中更为常见。考虑到加工肉类和饮用水的摄入量，年龄较小和较大的儿童组的平均亚硝酸盐摄入量分别为 ADI 的 21.9%和 22.9%。研究结果表明，在过去 10 年中，儿童从加工肉制品中摄入的膳食亚硝酸盐量有所下降，这可能是由于食物偏好的改变以及肉类行业在腌制肉制品中减少使用亚硝酸盐所致。
