  • Title: Analytical monitoring of alcoholic fermentation using NIR spectroscopy.
    Author: Blanco M, Peinado AC, Mas J.
    Journal: Biotechnol Bioeng; 2004 Nov 20; 88(4):536-42. PubMed ID: 15470716.
    Abstract:
    Alcoholic fermentation under Saccharomyces cerevisiae yeasts is governed largely by glucose uptake, biomass formation, ethanol and glycerin production, and acidification. In this work, PLS calibration models were developed with a view to determining these analytical parameters from near infrared spectra and analytical data provided by the corresponding reference methods. The models were applied to a set of samples obtained from various fermentation processes. The glucose, ethanol, and biomass values predicted by the models exhibited a high correlation with those provided by the reference method.
