Sažetak
The stability of lavender, lemon balm, mint, sage and thyme teas was investigated using in vitro simulation of the digestive system. Kinetics of changes in the total polyphenolic content and the antioxidant activity during the in vitro trials were also evaluated. Results showed that total polyphenolic content of mint teas decreases the fastest. Mathematical models for prediction of the total polyphenolic content and the antioxidant activity of prepared teas based on UV-VIS and NIR spectra collected before, during and after simulation showed that the best prediction was obtained for the wavelength ranges from 410 to 900 nm, 904 to 928 nm and 1399 to 1699 nm. It was concluded that the NIR can be used for calibration, validation and classification of teas prepared from Lamiaceae plants.
