Research in the article is aimed to determining the quality of flour from different systems of the technological process of a wheat milling. Samples of flour were obtained at the mill "Rivne Boroshno". Private enterprise "Rivne Boroshno" is one of the largest producers of wheat flour in the western region with a capacity of 180 tons /day. Flour obtained from various systems of milling process, has a very large variety of quality indicators. Whiteness, Gluten Deformation Index, Gluten Content, Protein Content, Ash Content, Water Absorbing Capacity, FN, SD, the rheological properties of dough on the Mixolab device, as well as the quality of baked bread have been evaluated.During the study, the variability of flour quality indicators on various systems was found. Whiteness varied – from 1 to 71 units, Gluten Deformation Index – from 40 to 100 units, Gluten Content – from 2 to 36 %, Protein Content – from 9,8 to 18,2 %, the FN – from 275 to 374 s, SD – from 15 to 30,3 UCD, Ash Content – from 0,31 to 2,23 %, Water Absorbing Capacity – from 53,5 to69,7 %. In the process of grinding grain and intermediate products, more than twenty flour streams of different quality are producedat the flour mill. From these streams it is required to receive only one or several grades of flour. Naturally, if only one variety is produced, then all flows from different systems are sent to it. The weighted average quality indicators of flour should comply with the requirements of the standard for this grade in terms of Ash Content, Gluten Content, etc.The maximum Ash Content is observed in the streams from the last reduction systems, as well as from break systems in the milling process, where products with a large number of brans are milled. At the same time, the flour from the central parts of the endosperm is slightly less gluten, but more starch than in the flour from the peripheral parts of the endosperm, which are grinding on subsequent reduction systems. For the research, samples of flour were taken from each system of the technological process. For convenience, we have arranged them for quality using the indicator of whiteness. One of the main indicators of the quality of flour, which determines its grade, is whiteness. In the studied samples, the values of the whiteness index range from 71 to 1 unit.

The article investigates the influence of the application of different systems of basic tillage on the quality of winter wheat grain in short crop rotations of the Southern Steppe of Ukraine. It is established that the grain quality of winter wheat in the Southern Steppe of Ukraine is mainly determined by the genetic characteristics of the variety, but also largely depends on the conditions and technologies of cultivation. In winter wheat grain, which is used for food purposes, reserve proteins are important, which in winter wheat determine the baking properties of flour. In drought conditions, when the yield of winter wheat decreases, the protein content in its grain tends to increase. In wet years, on the contrary, there is a reverse pattern. According to experimental studies, wheat varieties have a negative correlation between grain protein content and yield. It is established that during 2016–2020 research shows almost the same pattern of action of different predecessors and systems of basic tillage on the formation of grain quality of winter wheat in arid conditions. It was found that, on average, according to all variants of research, only with the use of the system of tillage-free tillage received grain of winter wheat with a protein content of 12,5%, which met the requirements of the 2nd class. It is recorded that on average over five years of research on all tillage systems, grain of winter wheat with gluten content was obtained, the quality of which corresponded to the 3rd class. Different tillage systems caused a slight impact on the gluten content, which ranged from 20,6% to 21,1%. It is determined that the precursors have a certain effect on the protein content in the grain of winter wheat. The analysis of qualitative indicators showed that on average in five years of research, when growing winter wheat after a pair of black and a pair of green wheat with winter vetch, grain was formed, which in terms of protein content corresponded to the 2nd quality class. More protein was accumulated in winter wheat grain after a pair of black, which was 12,9%. After peas for grain, as well as a pair of green with a mixture of white mustard and peas, received a grain of winter wheat, which was the 3rd quality class. It was found that on average in five years of research, all variants of winter wheat were grown with gluten content, which met the requirements of the 3rd class. Black vapor and green vapor with winter veneer caused the accumulation of gluten at almost the same level with a small increase in the version with winter vetch up to 21,8%. The lowest level of gluten was obtained in the grain of winter wheat after peas per grain, which was 19,7%. In all variants of the experiment, sidereal steam with winter tillage and the use of tillage-free tillage had the best effect on the growth of winter wheat grain quality indicators. The grain of winter wheat was mainly formed in terms of quality, which allows it to be used for food purposes – mainly in the flour-milling and baking industries, as well as for export. It is established that it is important to further study the quality of winter wheat grain and other cereals in short crop rotations of the arid Southern Steppe of Ukraine, especially in climate change.

The bread-making quality of forty commercial winter wheat samples, grown in the western region of the CzechRepublic, and their flours (white flours with ash content of about 0.5%) prepared in a commercial mill was studied. Standard analytical methods (ash and protein content, wet gluten), amylolytic activity measurement (falling number), rheological investigation (alveograph, gluten index), sedimentation test and laboratory baking test were used for characterization of wheats and flours. In addition NIR method was used to calculate ash, wet gluten, sedimentation value and protein content. Statistically significant correlations were found practically between all tested quality parameters of wheat and corresponding flour samples. However, the strongest correlation (r = 0.69–0.70) significant at 0.01 level exists between specific bread volume and protein and wet gluten content, determined both by standard or by NIR methods.

The results of studies of the quality of food and non-food grain of wheat from the southern regions of Ukraine in 2016 harvest are presented. The indicators of the quality of wheat grain were determined, the uniformity of their distribution in different classes of wheat was assessed, the content of protein fractions of the gluten complex and the molecular weights of individual protein structures were determined. It was found that the studied 13 samples of wheat grain had the following quality indicators: moisture content 9.4 ... 13.5%, bulk density 731 ... 814 g/l, protein content 10.1 ... 13.2%, gluten content 16.4 ... 25.6%, gluten quality 50 ... 110 units of the IDK device, falling number 311 ... 493 s, grain admixture 1.2 ... 10.5%, grains damaged by a wheat bug, 0.1 ... 10.1%. It was noted that the bulk density of all samples of wheat of 2 ... 6 classes exceeded the standard values in each class. In terms of protein content, 2 from 3 samples of class 5 wheat and 1 from 2 samples of 6 class exceeded the standard value of class 3 wheat (≥11.0%). The same was observed for these samples and for the gluten content (≥18%). Almost all grain samples, except for 2 samples of the 5th class and 2 samples of the 6th class, met the requirements of wheat of the 2nd class (45 ... 100 units device VDK). The falling number of all samples was high and significantly exceeded the normalized value (180 s), even for class 2 wheat. It was found that the uniformity of the distribution of individual quality indicators in different classes of wheat grain by the coefficient of variation is not the same. Such indicators of grain quality as moisture content, bulk density and protein content in different samples of the south of Ukraine in 2016 harvest fluctuated weakly (V≤10%), in terms of the amount of gluten and the falling number fluctuations were average (10% ≤V≤20%). Fluctuations in the content of grain impurities and grains damaged by the wheat bug are big (V≥20%). For the last indicator, fluctuations relative to the average are very large and exceed 120 %. This indicates that in different areas where wheat was grown, the infestation by the wheat bug was very different. It was shown that regardless of the total amount of protein determined by the Infratec FOSS express analyzer, four protein fractions of the gluten complex (albumins, globulins, gliadins and glutenins) are present in all grain classes, and the molecular weights of the protein structures of the main fractions are within small limits, which are in kDa - for albumins and globulins 20...30, gliadins 27.. 100 and glutenins 30...35. It was noted that in the varietal wheat "Chernobrova" albumins and globulins have a slightly higher molecular weight (30...40 kDa) than in non-varietal wheat.

Improving the quality of wheat grain is an important task of agricultural production. In recent years, the production of strong and valuable wheat, necessary for the production of high-quality baking flour, has decreased. In this regard, the study of the quality of grain varieties of winter wheat in specific soil and climatic conditions of the Rostov region is becoming topical. Therefore, the purpose of our research was to study the main indicators of grain quality of varieties of soft winter wheat (protein and gluten content, flour strength, bread size from 100 g of flour) in ecological variety trials to select the best under conditions of the Rostov region. The studies were carried out on the trial fields of the Laboratory of selection and seed production of winter soft wheat of intensive type of the State Scientific Establishment “Agricultural research center «Donskoy»” (Rostov region) in 2014–2016. Seventy-five varieties were studied in the course of the research. Planting dates – optimal for implementation of agricultural and agro-technical measures. Planter – «Wintersteiger Plotseed S.» Seed placement depth – 4–6 cm. Preceding crop – black fallow. Accounting square of fields – 10 m2, double replication. Seeding rate – 4.5 million seeds per hectare. Grain quality was assessed according to the methods of the national standards of the Russian Federation. Such grain quality indicators as gluten content (according to GOST R 54478-2011), protein mass fraction (as required by GOST 108460-91), baking properties of flour (in a laboratory using the remix method) were determined. The article discusses the main indicators of the quality of grain and flour of winter soft wheat varieties in ecological variety testing and compares them. Analysis of the main indicators of the quality of varieties in trials showed that in the south of the Rostov region in 2014–2016 flour strength and gluten content were the most variable indicators. In terms of protein content (> 14.5 %), 8.0 % of the studied varieties were in full compliance with strong wheat standards; by the gluten content (> 28 %) – 7.0 %; by the flour strength (>280 e.a.) – 9.0 %. Five varieties of winter soft wheat: ‘Aksinya’, ‘Tanais’, ‘Asket’, ‘Nakhodka’, ‘Yumpa’ (Russia) with a complex of economically valuable traits are of greater interest for practical breeding in terms of improving grain quality.
