description

Abstract A fast, reliable and economical methodology has been developed to control the production process of sugar-based depilatories. The method is based on the use of attenuated total reflectance—Fourier transform infrared (ATR-FTIR) spectroscopy in combination with multivariate data analysis. A very simple sample preparation process involving the dissolution of samples in water was applied. Employing a multivariate calibration model established from data of 15 well characterized samples, prediction errors equal or below 3.04 mg mL−1 for the quantitative determination of fructose, glucose, sucrose, maltose and maltotriose were obtained. Results found in this preliminary study indicate a great potential for the development of at-line ATR-FTIR-PLS methods based on a careful selection of variables from IR spectra, delivering fast and reliable results. As a reference method, a liquid chromatography (LC)–IR method was adapted for sample characterization.
