Abstract. The work is devoted to studying the composition for grain (barley and wheat) by terahertz (THz) high-resolution gas spectroscopy. The comparison of the set of chemical compounds formed during thermal decomposition of grain and cereals produced from grain was carried out with using a high-resolution spectrometer with phase-switching of radiation in the range of 115-175 GHz acting on studied gas developed by the authors. Free online spectroscopy databases were used for identification of substances. The results of comparison of molecular profiles of gas mixtures of thermal decomposition products of two varieties of barley, pearl barley and one variety of wheat are presented. Good agreement of the molecular composition for barley and pearl barley and some difference from the composition of the mixture obtained by heating wheat are shown.

Key words: high-resolution THz spectroscopy, grain, wheat, barley, chemical composition, products of thermal decomposition.

Financing: The software for processing the spectroscopic data from spectrometers was developed under the State Assignment FFUF-2022-0006. The spectroscopic measurements of gas mixtures obtained at thermal decomposition of grain samples were carried out under the State Assignment FFUF-2024-0024.
