Abstract:

目的对深圳市售乳制品中硫氰酸盐含量进行检测,了解乳制品中硫氰酸盐的本底含量。方法监测点分布于全市9个区的超市,随机抽取市售乳制品196份,采用离子色谱法测定乳制品中硫氰酸钠含量。结果196份乳制品硫氰酸钠检出率为100%,检测值为2.29~51.8mg/kg。成人乳粉和婴幼儿乳粉硫氰酸钠检出值均较高,均值分别为24.38mg/kg和24.45mg/kg,液态奶硫氰酸钠检出值较低,均值为6.46mg/kg。将乳粉中硫氰酸钠含量折算称生乳中含量,成人和婴幼儿乳粉硫氰酸钠含量均值分别为3.17mg/kg和3.18mg/kg,均低于液态奶中硫氰酸钠均值含量6.46mg/kg。深圳市居民通过乳粉和液态奶,硫氰酸钠的暴露量为6.05μg/kg和12.33μg/kg标准人每日。结论市售乳制品中硫氰酸盐检出率高,尤其婴幼儿乳粉值得关注,非常有必要对我国生鲜乳中硫氰酸盐的正常生理浓度开展全面的调查,保障人民健康。
