eng Application of Chemometrics Methods and Electronic Nose as a Simple and Fast Tool for the Classification of Different Types of Alcoholic Beverages An Electronic nose (E-nose) is an analytical instrumental method which allows analysis of aroma of samples. This work uses E-nose to determine the characteristic aromas of seven different types of alcoholic beverages (bourbon, cognac, vodka etc.). Three chemometrics methods such as principal component analysis (PCA), discriminant factorial analysis (DFA) and soft independent modeling of class analogies (SIMCA) were used and compared. The results show that chemometrics methods PCA and DFA allow determination of individual alcoholic groups of fruit spirits, bourbon, cognac and brandy but they face difficulty with separation of liqueur, gin and vodka points from one group. Only the SIMCA method allowed distinguishing the point belonging to all groups without any approximation of graph fragments. Electronic Nose; Chemometrics Methods; Alcoholic Beverages
