生鲜牛乳中硫氰酸钠的风险评估研究

摘要

采用离子色谱法对上海地区的500批次生鲜牛乳中硫氰酸钠含量进行检测。结果表明：生鲜牛乳中硫氰酸钠含量总体情况符合Pearson5分布（皮尔逊V型分布），90％的数据分布在0．2～3．71 mg/kg之间，最小、最大、平均含量分别为0．2、9．66和1．5 mg/kg。基于乳制品中硫氰酸钠的每日摄入量和点评估方法得到硫氰酸钠的膳食暴露量为2．0μg/kg标准人每日，结合相关的硫氰酸钠的风险评估研究，表明本研究中上海地区生鲜牛乳中的硫氰酸钠的含量属于正常的生理浓度，对人体正常膳食无健康影响。%Sodium thiocyanate in raw milk for 500 batch samples in Shanghai was tested and analyzed by ion chromatographic method .The results show that sodium thiocyanate in raw milk was accord with Pearson 5 distribution in general.The percentage of 90 was during 0.2 to 3.71mg/kg.The minimum, maximum and av-erage value was 9.66, 0.2 and 1.50mg/kg.Based on sodium thiocyanate in milk product intake and point e-valuation method , sodium thiocyanate dietary exposure was 2μg/kg one day for one person .According to other risk assessment associated with sodium thiocyanate , the concentration of sodium thiocyanate in raw milk in Shanghai area by the study was of normal physiological concentration .It was no health effects on the human body by normal diet .
