dc.description.abstractIn this work we have studied the near-infrared reflectance spectra of sunflower meal to develop of calibration equation for moisture content determination. Sunflower meal samples with different humidity that varied from 5 to 19 % were investigated. Investigations were carried out on the spectrometer „Infrapid -61” in the range of wavelength 1330-2370 nm through 10 nm. It was detected that 1460 and 1930 nm wavelengths are characteristic for moisture content determination of sunflower meal using reflectance coefficient. Analysis of first and second derivatives from the optical density spectra gave possibility to detect their characteristic wavelengths, which were moved to low wavelengths region and were located at 1400 and 1890 nm for the first derivative of the optical density spectra and at 1370 and 1860 nm – for the second derivative of the optical density spectra. Calibration equations are developed and value of probable approximation are obtained. It is possible to determine moisture content of sunflower meal using wavelength mentioned above.uk_UK
