    Fourier Transform Near Infrared (FT-NIR) spectroscopy was used to assess the chemical composition of fresh honey samples. Samples (n = 42) were obtained from beekeepers, small shops and supermarkets in Brno and surroundings. The sample parameters (watercontent, water activity, electrical conductivity, pH and HMF) were assessed using both standard methods and FT-NIR spectroscopy. Honey samples were scanned in transflectance (0.5 mm path-length) in a FT-NIR Analyser in near infrared region (10 000 ? 4 000 cm-1). Calibration models were developed using partial least squares method and verified by cross validation. The following statistical values were obtained: correlation coefficient of calibration R = 0.99 and standard error of cross validation SECV =0.33 for water content, R = 0.97 and SECV = 0.01 for water activity, R = 0.90 and SECV = 0.17 for pH, R = 0.99 and SECV = 18 for HMF, R = 0.99 and SECV = 14 for electrical conductivity. The results demonstrate that near infrared spectrome
