| Abstract: | In this paper, Fourier transform infrared spectroscopy combined with two-dimensional （2D） correlation spectroscopy was used to investigate the melamine of milk. The sample adulterated with concentration of melamine （3 g/L ） was prepared and the infrared spectra were measured at different temperature. Then the 2D correlation spectroscopy was calculated under the perturbation of temperature. In the range between 1 400 and 1 800 cm-1, three autopeaks were aroused at 1 448 cm-1, 1 552 cm-2 and 1 640 cm-2 in synchronous spectrum, which are the absorbance features of melamine in milk. The method can be used for a correct discrimination on whether the milk is adulterated. The study is important to improve the quality of dairy products and to protect the benefits of consumers. |
