目的 通过对赋码奶粉易撕盖进行质量和食品安全测试分析，研究赋码技术对奶粉易撕盖带来的质量安全风险。方法 分别对赋码奶粉易撕盖进行表面摩擦试验、耐腐蚀性测试，以及食品安全符合性测试和非靶向筛查分析，评价赋码后奶粉易撕盖的质量性能和食品安全风险。结果 赋码奶粉易撕盖表面经摩擦测试，未产生明显的黑灰物质，且赋码位置具备一定的耐腐蚀性能;赋码奶粉易撕盖的食品安全符合性测试可满足相应国标要求，经非靶向筛查，赋码易撕盖不会对奶粉带来食品安全风险。结论 赋码技术对奶粉罐易撕盖产生的质量安全风险较低，赋码易撕盖可用于奶粉包装。

The work aims to analyze the quality and safety risks brought by the coding technology applied on milk powder peel-off ends through analyzing and testing the quality and food safety of coded milk powder peel-off ends. Surface friction tests, corrosion resistance tests, food safety compliance tests, and untargeted screening analyses were conducted on coded milk powder peel-off ends to evaluate the quality performance and food safety test results. The results showed that no black or gray substances were found after the surface friction tests, and a certain level of corrosion resistance was found on the coded area. In addition, according to the results of the food safety compliance tests, coded milk powder peel-off ends fulfilled the corresponding international requirements. Through the untargeted screening analyses, it was found that food safety risks would not be brought by coded peel-off ends. The risks brought by the coding technology applied on milk powder peel-off ends are low. Therefore, coded peel-off ends could be used on milk powder packaging.
