配方注册婴幼儿配方乳粉中蛋白质及三聚氰胺含量测定分析
目的通过测定婴幼儿配方乳粉中蛋白质及三聚氰胺含量, 对我国现阶段配方注册的婴幼儿配方乳粉安全状况进行监测。方法婴幼儿配方乳粉中蛋白质的含量依照GB 5009.5-2016《食品安全国家标准 食品中蛋白质的测定》中“第一法 凯氏定氮法”进行检测; 三聚氰胺的含量依照GB/T 22388-2008《原料乳与乳制品中三聚氰胺检测方法》中“第一法 高效液相色谱法”进行检测。结果样品中蛋白质含量均符合食品安全国家标准规定, 且满足测定值不小于标签标示值80%的规定; 三聚氰胺的含量均为未检出或低于检出限, 符合原卫生部公告的限量值规定。结论根据食品安全国家标准或推荐标准的检测方法和评价指标, 所检测的样品中蛋白质项目满足配方注册要求。
ObjectiveTo monitor the safety of infant formula milk powder registered in China by measuring the content of protein and melamine in infant formula milk powder. MethodsProtein content in infant formula milk powder was determined according to the first method-Kjeldahl method in GB 5009.5-2016 National food safety standards-Determination of protein. The content of melamine was detected according to the first method-high performance liquid chromatography (HPLC) in GB/T 22388-2008 Testing methods for melamine in raw milk and dairy products. ResultsThe protein content in the samples all met the national food safety standards, and the measured value was not less than 80% of the labeled value. Melamine content was not detected or less than the detection limit, in line with the limit value in the announcement of former ministry of health. ConclusionAccording to the testing methods and evaluation indexes of national food safety or recommended standards, the protein content in tested samples meet the requirements of formula registration.
