The diffuse reflectance spectra of hops were investigated in order to create a rapid method of assessing the quality of granulated hops with simultaneous determination of key indicators (without the use of chemicals and prolonged dry). Researches have been conducted on the infrared analyzer "Infrapid-61" in the wavelength range 1,33-2,37 microns.
Thus, it is possible to determine moisture content of sunflower meal using obtained calibration equations and wavelengths mentioned above. The study of reflectance spectra peculiarities makes it possible to more widely use NIR spectroscopy method for rapid determination of fat, protein, moisture and other substances content in oilseeds, in their byproducts and meals (whether it be storage or processing stages).
