CARMEN MIHAELA TOPALA, LAVINIA DIANA TATARU ATR-FTIR SPECTROSCOPY COUPLED WITH CHEMICAL AND CHEMOMETRIC ANALYSIS TO DISTINGUISH BETWEEN SOME SWEET WINES FTIR Spectroscopy correlated with some chemical characteristics and chemometric analysis have been applied to distinguish between sweet wines obtained from different Romanian varieties and Canadian icewine. Chemical analyses differentiate the two categories of origin in terms of sugar content, acidity and total polyphenol content but are expensive and time-consuming. Principal Component Analysis were performed using different regions of FT-MIR spectra for all wines. Principal Component Analysis of their chemical parameters indicated that the wines can be discriminated based on their different phenolic, carbohydrates, polyols content and geographical origin. FTIR spectroscopy coupled with chemometry is a profitable technique for distinguishing between different wines and validates the results obtained by chemical analysis.
