“…6D the pyrogram of the melamine formaldehyde WPC is displayed, which shows all products typical for such a type of resin [15]. The key marker compounds in this case are melamine, methylmelamine, and dimethylmelamine, which to a certain extent can also be found in the prepyrolysis chromatogram.…”

“…The presence of benzoin and terpenoid compounds including colophony, sandarac, manila copal, elemi and amber was presented. Analytical pyrolysis and thermochemolysis-TMAH was also used in the analysis of melamine resins and a melamine polyester copolymer [69]. Thermochemolysis was found to be a sensitive technique for the detection of methylated melamine.…”

“…Previous studies on melamine and its derivatives were mostly performed in environmental and chemical sciences (Ono and others 1998; Yokley and others 2000; Leidl and Schwarzinger 2005; Sancho and others 2005; El‐Sayed and others 2006). High‐performance liquid chromatography coupled with mass spectroscopy (HPLC‐MS) is the principal analytical method currently used by the Food and Drug Administration (FDA) for detection and quantification of melamine in foods.…”

Melamine, a nitrogen-rich chemical, was implicated in pet and human food recalls in 2007, which caused enormous economic losses to the food industry. In this study, melamine concentration in wheat gluten, chicken feed, and processed foods (that is, cake and noodle) was measured by surface enhanced Raman spectroscopy (SERS) in combination with SERS-active substrates. SERS was able to rapidly detect 0.1% melamine in wheat gluten, 0.05% in chicken feed, 0.05% in cakes, and 0.07% in noodle, respectively. A partial least squares (PLS) model was established for the quantification of melamine in foods by SERS: R= 0.90, RMSEP = 0.33. In addition, SERS results were verified by HPLC analysis based on a simplified FDA method. Compared with HPLC, the SERS method is much faster and simpler, requires minimum sample preparation, but still yields satisfactory qualitative and quantitative results. These results demonstrate that it is an applicable approach to use SERS to screen foods, eliminate presumptive negative samples of melamine contamination from the sample population, and then verify presumptive positive samples using HPLC protocols. Combining these 2 methods could provide a more rapid and cost-effective way for monitoring melamine contamination in increasingly large numbers of imported foods and feed products.
