Abstract
This paper describes the use of Fourier Transform Infrared (FT-IR) spectroscopy coupled with an Attenuated Total Reflectance (ATR) accessory to quantify the individual sugars (glucose, maltose, maltodextrins...) in a mixture extracted from a process of wheat transformation into sugar. ATR accessory allows us to analyze very viscous media such as molasses by pouring the medium on a flat crystal. In the first step, model mixtures are prepared in the concentrations common to sugar industries and are analyzed by an FT-IR spectrometer. Binary (glucose/maltose) and ternary (glucose/maltose/maltotriose) solutions are used. Spectra are recorded from 1300 to 850 cm-1. Multivariate mathematical processing methods are applied to these spectra (Partial Least Squares and Principal Component Regression). The results show a very good discrimination between the different sugars.
