FOURIER TRANSFORM INFRARED SPECTROSCOPY IN MONITORING THE WINE PRODUCTION
Abstract
The complexity of the wine matrix makes the monitoring of the winemaking process crucial. Fourier Transform Infrared Spectroscopy (FTIR) along with chemometrics is considered an effective analytical tool combining good accuracy, robustness, high sample throughput, and “green character”. Portable and non-portable FTIR devices are already used by the wine industry for routine analysis. However, the analytical calibrations need to be enriched, and some others are still waiting to be thoroughly developed. For this reason, an extended literature review took place identifying gaps for further research meeting the needs of the modern wine industry (Thanasi et al., 2022). The methodology that was followed was based on grouping the different studies according to the main sampling material used – 1) leaves, stems, and berries; 2) grape musts; 3) wines. For each sampling material the studies were categorized in terms of 1) main aim of the analysis; 2) type of sample; 3) sample preparation mode;4) wavenumber range (/cm); 5) spectral pre-treatment; 6) statistical method.
The most important findings were: 1) the different sample preparation modes can influence the spectra;
