Analysis of the Results of Proficiency Testing of Folic Acid in Infant Milk Powder
Objective:In order to improve the laboratory's ability to detect folic acid in infant food and milk powder,the laboratory participated in the proficiency testing activity of"Determination of Folic acid in Infant formula milk Powder"(CNCA-21-01),which was organized by State Administration for Market Regulation and coordinated and implemented by Hebei Food Inspection and Research Institute.Methods:Based on rhamnose lactobacillus specificity and sensitivity of folic acid,two commercial kits were used to quantitatively determine the content of folic acid in the test sample NLYZ-YS-089,and the determination results were analyzed and evaluated.Results:The inspection sample NLYZ-YS-089 test results of 149 μg/100g,Z value is 0.74,|Z|less than 3,comparing the results between the proficiency testing lab for satisfaction.Conclusion:Our laboratory has a good ability to detect folic acid in infant formula food and milk powder,which lays a solid foundation for maintaining and improving the determination ability of folic acid in infant formula food and milk powder.
