Trace Detection of Melamine in Dairy Products

This technical report outlines the detection of melamine in dairy products using the Metrohm Instant SERS Analyzer (Misa). The report details the background of melamine's illicit addition to milk, which gained global attention due to health risks associated with contaminated dairy products. It describes the methodology for establishing a standard SERS reference spectrum for melamine and the experimental procedures for testing dairy samples spiked with melamine. The results section presents findings on the reliable detection of melamine at concentrations as low as 5 μg/mL in light cream. The report concludes by summarizing the requirements for field test protocols and emphasizes Misa's capabilities for rapid and cost-effective on-site identification of food contaminants. The document serves as a guide for users to understand the practical application of Misa in detecting food adulteration, particularly in dairy products.
