ISO 7124:2023— Eggs And Egg Products

Quality control expert inspecting  chicken eggs in the laboratory with a liquid chromatography method that adheres to ISO 7124:2023.

The color of an egg shell is strictly a function of the breed of the bird. You can usually tell what color egg a chicken will lay by looking at the color of her earlobe. Hens with white ears produce white eggs, hens with red ears produce brown eggs, and hens with bluish-green ears produce bluish-green eggs. All eggs, no matter the color, are packed with proteins and nutrients. ISO 7124:2023— Eggs And Egg Products – Determination Of Fipronil And Metabolites Residues – Liquid Chromatography Tandem Mass Spectrometry Method covers a liquid chromatography test method for eggs and egg products.

Liquid Chromatography for Eggs

Liquid chromatography (LC) is a separation technique in which sample ions or molecules are dissolved in a liquid mobile phase. It is used to separate proteins, nucleic acids, or small molecules in complex mixtures. Further, in a food or drink sample chromatography separates mixtures and analyzes the components for any harmful pollutants that could infect the food or drink.

Liquid chromatography tandem mass spectrometry (LC-MS/MS) is a powerful tool for the detection of residual chemical compounds, confirmatory identification of small organic molecules, and confirmation and quantitation of contaminants and adulterants in pharmaceutical and food samples—for example, vanilla. It has been used as a means of egg protein analysis or for the separation or the purification of egg yolk or egg white proteins.

What Is ISO 7124?

ISO 7124:2023 specifies a liquid chromatography tandem mass spectrometry method (LC-MS/MS) for the determination of fipronil and metabolites (including fipronil-desulfinyl, fipronil-sulfide and fipronil-sulfone) residues in eggs and egg products. The standard details requirements for preparing and storing the test sample. The test sample consists of either fresh eggs and egg products with shell or other egg products. For conducting the procedure of the (LC-MS/MS) method, ISO 7124:2023 details specifications for reagents, preparation of solutions, materials, apparatus, and calculations methods for the test report.
