This application note details a rapid method that combines a specific solid phase extraction (SPE) method for melamine in liquid milk and infant formula with UPLC®/MS/MS detection that can enable detection and quantitation of melamine across a wide range of concentrations.
US FDA has stated that no tolerance can be set in infant formula(4) and Taiwan has declared that melamine should not be detected in any food using the most sensitive instrumentation. Cyanuric acid is a structural analogue of melamine and may be found as an impurity of melamine.
30 kwi 2010 · This paper describes a simple method to determine the melamine contamination in infant formula samples using isocratic, reverse phase HPLC. This method is advantageous because the mobile phase is acetonitrile-free and the analysis time of ∼6 min per sample is reasonably rapid.
1 mar 2020 · For the calibration set, samples in a concentration range of 0.0%–5.5% (w/w) melamine in infant formula were prepared in steps of 0.5%. The test set samples were arbitrarily set to levels of 0.55, 1.25, 2.25, 3.10, 3.75, 4.35 and 5.35% melamine in infant formula.
22 mar 2018 · Results showed that chemometric models demonstrated a good predictive ability of melamine and cyanuric acid concentrations in infant formulas, showing that this is a rapid and accurate technique to be used in the identification and quantification of these adulterants in infant formulas. 1. Introduction.
15 lip 2011 · It was found that infrared spectroscopy is an effective tool to detect melamine in dairy products, such as infant formula, milk powder, or liquid milk.
A liquid chromatography triple quadrupole tandem mass spectrometry (LC-MS/MS) method for residues of cyanuric acid (CYA) and melamine (MEL) developed by the Center for Veterinary Medicine (CVM)...
