摘要: 文章概述了国内外生鲜乳中硫氰酸盐的使用情况,对上海地区500份生鲜乳进行硫氰酸钠含量分析,对272份生鲜乳中硫氰酸钠含量和菌落总数含量进行分析比较,并对其进行风险评估研究。结果表明:①生鲜乳中硫氰酸钠含量总体符合Pearson5分布,90%的含量在0.2~3.71 mg/kg之间,最大含量、最小含量和平均含量分别为9.66、0.2和1.5 mg/kg。②272份生鲜乳中菌落总数含量在110~1100000 CFU/mL,97.5%的含量在110~300000 CFU/mL。生鲜乳中硫氰酸钠含量和菌落总数含量相关性不明显,硫氰酸钠含量未对菌落总数含量产生明显影响,R2=0.02。③基于生鲜乳中硫氰酸钠的平均含量和最大含量得到,个体每千克体重硫氰酸钠的平均暴露量和最大暴露量分别为0.0025和0.016 mg。结合相关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。

Abstract: Thiocyanate used in raw milk both at China and foreign was summarized. 500 batches in Shanghai were tested and analyzed. 272 batch samples were analyzed and compared. Risk assessment research was developed. The results showed that sodium thiocyanate in raw milk was accord with Pearson5 distribution in general. The percentage of 90 was during 0.2 to 3.71 mg/kg. The maximum, minimum and average value was 9.66, 0.2 and 1.50 mg/kg,respectively. Colony count of 272 batches were during 110 to 1100000 CFU/mL, The percentage of 97.5 was during 110 to 300000 CFU/mL, Sodium thiocyanate content and colony count was not obvious correlation, the content of sodium thiocyanate had no effect on the colony count significantly. Correlation efficient was 0.02. Based on the medium and maximum sodium thiocyanate content, sodium thiocyanate dietary medium and maximum exposure was 0.0025 and 0.016 mg one day for one person. Associated with other risk assessment of sodium thiocyanate, the concentration of sodium thiocyanate in raw milk in Shanghai area was normal physiological concentration. It had no health effects on the human body in normal diet by the study.

Key words: raw milk; sodium thiocyanate; colony count; risk assessment
