For determination of melamine methods of reversed phase and ion-pair high-performance liquid chromatography, and also immune-enzyme analysis are used. The purpose of our work was working out of a technique of determination melamine in milk and lactiferous products method CZE. As a result of researches determination conditions melamine in foodstuff by method CZE (sensitivity from 0.8-1.0 mg/l) are developed, and also conditions of its isolation from objects of research are adapted.

Melamine, as a toxic compound, needs to be controlled in food, especially in dairy products. In this systematic study, quantities of melamine and cyanuric acid in various types of milk were investigated. A comprehensive database search was performed using the keywords pasteurized milk, milk, sterilized milk, melamine, and cyanuric acid without time limitation.

This work presents two novel devices with a microcontroller and two different light sensors, namely, Light Dependent Resistor (LDR) and Ambient Light Sensor (ALS), which can provide a quantitative output from the colorimetric variations of citrate capped borohydride reduced silver nanoparticles (AgNPs) and citrate capped gold nanoparticles (AuNPs) upon addition of melamine adulterated milk. The limit of detection (LOD) of the LDR setup with AgNPs and AuNPs was found to be 1.24 ppm and 1.
