The large varieties of hops and hop products used in the brewing industry. Various in the biochemical composition, individual approaches to the brewing technology of each hop product are required in order to obtain a high-quality beer with a characteristic bitter taste and aroma. The purpose of this work was to study the biochemical composition of pressed conical hops, pellets of hop type 90, type 45, ethanolic and CO2 extracts of hop of various varieties, and their influence on the quality of the finished beer. As a result of comprehensive research on hops and hop products of various varieties, using the modern biochemical methods were determined differences in their biochemical composition depend on the absolute values such parameters as the mass fraction of α-acids, b-acids and their composition, xanthohumol, general polyphenols, essential oils, the ratio of their valuable components of hops: b-acids to a-acids and also for quantity of general polyphenols, essential oils per unit of α-acids. Based on the results of the biochemical composition of hops and hop products were investigated their influence on the quality of beer and were determined their using in brewing.
The veterinary and sanitary assessment results of food products according to SLVSE agro-food markets of Zhytomyr and Zhytomyr region and Zhytomyr regional state laboratory of the Service of Ukraine for Food Safety and Consumer Protection for 2021 are presented. In total, 68.151 tons of products were not allowed to be sold, and 8866 positive research results were obtained, including 50 carcasses and 3305 cases of invasive and non-communicable diseases. The main reason for the rejection of offal in 2021 was invasive and non-communicable diseases, which significantly worsened the sanitary indicators of product quality. MAFAnM of the liver, which was cleaned due to fasciolosis, is higher than in the same organ obtained from healthy animals by 86.0 %. The highest percentage of affected samples for E. coli was found in the study of the lungs (50.0 %), in the presence of Klebsiella – the heart (50.0 %.). In terms of quality and safety (the content of toxic elements, pesticides, mycotoxins, antibiotics, radionuclides), the studied 212838 food samples in 47 exceeded the content of 137Cs following the State Hygienic Standards. The most dangerous are the gifts of the forest. Excess was found in 30 samples of fresh mushrooms and 13 – dry. The specific activity of 137Cs in the sample of fresh mushrooms from Popelny exceeded DR-2006 6.9 times, five samples from Lugin – 1.4–2.0 times, nine samples from Narodychi – the maximum exceedance 2.2 times, six samples from Novograd – 1.2–1.8 times, six samples from Ovruch – 1.2–1.7 times. The specific activity on the content of 137Cs in 3 samples of dried mushrooms from Narodychi exceeded DR-2006 by 2.1–6.7 times, two samples from Olevsk – by 1.6 and 5.6 times, 1 sample from Lugin – by 2.6 times, four samples from Ovruch – 1.0–1.6 times, three samples from Yemilchino – 1.0–1.1 times). The system of monitoring sanitary-hazardous pathogens and residual amounts of toxic substances and radionuclides remains the guarantor of food safety in Ukraine. To eliminate the risk of food consumer hazards, it is necessary to improve the control system of raw materials used to manufacture products, safety indicators at all stages of production “from the field – to the table”, and remove substandard products.
<p><span lang="EN-US">We considered the influence of varietal features of wheat grain on the degree of its infection by granary weevil and the change of quality indices grain of crop at the pest infestation. We stidued the samples of grain of winter wheat of soft varieties of Oriyka, Zluka, Forest song and spring durum Kharkovskaya 27 variety. Our study consisted in determining the technological and sowing parameters of wheat grains of different varieties after the 1 month of storage (after passing the post-harvest ripening) and after 12 months of storage (after infection of grain by granary weevil). After passing the post-harvest ripening, the wheat grain of all studied varieties was suitable for technological, seed and fodder purposes and grain Kharkovskaya 27 for the food purposes. After 12 months of storage, the most populated barn weevil was wheat grain of winter soft variety Forest song (more than 3000 pieces in one kilogram in obvious form and 34 % in hidden form). The least infected was grain of spring wheat durum Kharkovskaya 27 (about 500 pieces in one kilogram). The difference in the infection of the wheat grain of the studied varieties is explained by the different hardness of the grain. After 12 months of storage, the population with a granary weevil of wheat grains of all studied varieties promoted an increase in the moisture content and content of foreign materials and carried out to decrease in the characteristics of </span><span lang="EN-GB">grain-unit</span><span lang="EN-US">, energy of germination, germinating ability, content of protein and gluten.</span><span lang="EN-US">In the varieties of Oriyka, Zluka and Kharkovskaya 27 energy of germination and germinating ability decreased from 3 till 10 % compared to the initial indices. We observed the most significant decrease in the sowing indices in the variety of Forest song: by 58% less than the initial value of the energy of germination and by 51 % less than germinating ability. We concluded that the wheat grain of the spring durum Kharkovskaya 27 was the most resistant to infection of granary weevil and the preservation of technological quality indicators was.</span></p>
In the world, the demand for quality and safe grain products is increasing. The need to preserve wheat in the event of a natural disaster requires the study of optimal storage times of grain without degrading technological indexes. The purpose of the work was to study the dynamics of technological properties of winter wheat grown after peas, clover, corn for silage and the industrial, ecological, biological growing systems during 1, 3, and 5 years of storage in the conditions of the ordinary granary. The absence of significant differences in the technological parameters of the grain of wheat grown at industrial and ecological systems, but significantly lower indicators at a biological growing system was found. The highest hectolitre weight obtained when wheat grain was grown after corn for silage, and vitreousness – after the clover. Significantly higher biochemical parameters of grain and alveographic properties of flour were for the cultivation of wheat after peas, which provided additional accumulation of protein substances. There are no significant changes in the indicator of hectolitre weight during the grain storage. Other indicators increased significantly after 1 year of storage (on average by 10 – 30%). For further storage, vitreousness growth was insignificant. After 5 years of storage, the falling number significantly increased (on 21% compared to the initial values and on 7% – after 3 years of storage). The content of protein, gluten in the grain, and alveographic properties of flour significantly decreased after 5 years of storage. The possibility of obtaining grain of wheat with high technological parameters for a more safe ecological growing system was established. It was also confirmed to need for grain storage up to 1 year to improve quality indicators and it was established that it safely stored for 3 years.
