Discrimination between Mature Vinegars of Different Geographical Origins by NIRS

The feasibility of near infrared spectroscopy (NIRS) for discrimina-tion between mature vinegar of different geographical origins (Taiyuan and Qingxu, China) is presented in this research. NIR spectra were collected in transmission mode in the wavelength range of 800—2500 nm. Qualitative analy-sis models were developed based on Principal Component Analysis (PCA) and Discriminant Analysis (DA). The prediction performance of calibration models in different wavelength range was also investigated. The best models gave a 96.3% classification of mature vinegars of the two geographical origins in the range of 8002500 nm. The results demonstrated that NIRS technique could be used as a rapid method for classification of geographical origin of mature vinegars.
