The aim of present work is to develop an innovative and alternative method for the identification and quantification of methanol in white spirits based on twodimensional (2D) infrared spectroscopy. Firstly, for the identification and quantification of methanol in white spirits, 19 white spirits samples adulterated with different levels of methanol (0.1% to 10%) were prepared. And, the Fourier transform...
In this paper, a new method for discriminate adulterated milk was proposed by combining two-dimensional (2D) correlation infrared spectroscopy with multi-way partial least squares discriminate analysis (NPLS-DA). 64 pure milk samples were collected and four adulteration types of milk with urea, melamine, tetracycline and glucose were prepared, respectively. IR spectra of pure milk and adulterated...
