广东市售乳粉及乳制品中蛋白质和三聚氰胺监测结果分析

Analysis of monitoring results of protein and melamine in commercial milk powder and dairy products in Guangzhou

目的:对广东市售乳粉及乳制品中蛋白质与三聚氰胺含量的监测结果进行分析,为食品安全监管提供了依据。方法:随机抽检了3个地级市总共3个品种118宗市售乳粉及乳制品样本,按照GB5009.5-2010和GB/T22388-2003进行分析。结果:广东市售乳粉蛋白质合格率仅为76.7%,液态乳蛋白质的合格率为84.4%,含乳饮料蛋白质合格率为93.0%;而三聚氰胺的检测结果全部小于规定的国家标准值,合格率高达100%。结论:广东市售乳粉及乳制品中蛋白质含量监测结果表明:乳粉中蛋白质合格率偏低,因此对乳粉(特别婴幼儿乳粉)中蛋白质含量需要重点监测和严格监督。

Objective：To analyze the monitoring results of protein and melamine levels in commercial milk powder and dairy products in Guangdong,and provide a basis for food safety supervision.Methods： A total of 118 milk powder and dairy products samples in 3 kinds were randomly selected from 3 prefecture-level cities and analyzed in accordance with GB5009.5-2010 and GB/T22388-2003.Results： In Guangdong,the qualified rates of protein in commercial available milk powder,liquid milk and milk beverage were 76.7%,84.4% and 93.0% respectively,while the detection values of melamine were all lower than the national standard values,whose qualified rates were 100%.Conclusion： The qualified rate of protein in milk powder was low,so surveillance and supervision of protein level in milk powder,especially in infant milk powder,should be strengthened strictly.
