我国北方地区生鲜牛乳中硫氰酸盐含量调查
目的 调查我国北方地区生鲜牛乳中硫氰酸盐含量, 提出一个获得生鲜乳中硫氰酸盐本底值的方法, 并初步得到一个生鲜牛乳的硫氰酸盐本底值。方法 对北方11省市221个奶牛养殖场的生鲜牛乳样品进行SCN?的含量测定。结果 统计实验数据发现, 所有样品含有SCN-, 含量范围在0.21~6.10 mg/kg之间, 平均含量为2.09 mg/kg, 数值分布状态为平顶右偏态分布; 生鲜乳中硫氰酸盐含量与产地呈显著相关关系(P<0.05)。结论 虽然不同地区来源的生乳中硫氰酸盐含量差异显著, 但并没有造成数值过多的增加, 初步评估我国北方地区生鲜牛乳中SCN-本底值为6.10 mg/kg。
Objective To investigate the thiocyanate content in raw milk in northern China, propose a method for obtaining the background value of thiocyanate in raw milk, and obtain a preliminary background value of thiocyanate in raw milk. Methods The content of SCN- in the raw milk samples from 221 cow farms in 11 provinces and cities in north China was determined. Results The statistical experimental data showed that all samples contained SCN-, the content ranged from 0.21 to 6.10mg/kg, and the average content was 2.09 mg/kg. The numerical distribution state was a flat-topped right-skewed distribution. There was a significant correlation between the thiocyanate content in raw milk and the origin (P<0.05). Conclusion Although the content of thiocyanate in raw milk from different regions was significantly different, it did not cause excessive increase in the value, the background values of SCN- in raw milk in northern China is estimated to be 6.10 mg/kg.
