Continuing the approach adopted by Meurens et al. in dispersive NIR spectroscopy, the principle of using dry extracts is taken up in FTIR spectroscopy, yielding three advantages: the rapidity of Fourier transform spectroscopy, the solvent elimination, and a better peak resolution in the mid-IR. However, sampling appears more difficult in mid-IR than in NIR spectroscopy. In mid-IR spectroscopy, particular dry extract problems are: (1) the nature and the choice of the support, (2) the reproducibility of the signal, and (3) the feasibility of quantitative analysis. The performances of our dry-extract method are required here in terms of spectroscopy as well as of a multicomponent quantitative analysis of mixed sugars in aqueous solutions.
