To study the biochemical parameters characterising seed quality in pea varieties of different morphotypes for the selection of genotypes with improved nutritional properties. Methods. Seeds of 37 different morphotypes [leafy, leafless, heterophillous (chameleon)] of domestic and foreign pea varieties were studied. Standard and laboratory developed methods of biochemical analysis of plants (Kjeldahl method, spectrophotometric methods, electrophoresis) were used. The statistical analysis of the research results was carried out using the software LibreOffice Calc (GNU Lesser General Public License v3) and the image analysis software Imagel. Results. The presence of varietal differences in the biochemical parameters studied related to seed quality (protein content, flavonoids, lipoxygenase activity, trypsin inhibitor, lectins), the content of the main fractions of the protein complex (legumin and vicilin) and their ratio in seeds of different morphotypes was established. The electrophoretic and amino acid analyses revealed varietal differences (in the relative content of certain protein components in the electropherogram, the presence/absence of some components in the electrophoretic spectra of vicilin and legumin, and their amino acid composition) that affect the nutritional value of pea seeds. Conclusions. The application of the biochemical criteria studied makes it possible to select varieties of food peas with specific technological parameters. [ABSTRACT FROM AUTHOR]

The work shows that growing peas in Ukraine produces a significant amount of a secondary resource - unusedstraw, which is inexpedient from both economic and environmental points of view. This also contradicts current global trendsregarding the most efficient use of all available types of food and feed raw materials to ensure food security of the population,and reduce the negative impact on the environment. It is shown that the use of pea straw in the feed industry will allow returninga significant amount of natural resources into the chain of creating products for people, in addition, it will contribute toan increase in the production of animal protein. The reasons for the low efficiency of using straw as a component of enrichingthe nutritional value of compound feed products are given and the expediency of using it as a component with functionalproperties is shown.The aim of the work was to determine the effect of the consumption of flour from pea straw on the state of lipid peroxidationin the digestive system under conditions of experimental dysbiosis.We used flour from the vegetative parts of peas (straw). Dysbiosis was reproduced in rats using the antibiotic lincomycin.The state of lipid peroxidation (LPO) was studied by the content of malondialdehyde (MDA) in the tissues of the digestivesystem (mucous membranes of the cheeks, small and large intestines, as well as in the liver). Pea straw flour was added tothe compound feed in the amount of 10% instead of wheat grain. The experiment lasted 18 days. The activity of the antioxidantenzyme catalase was also determined, and the antioxidant-prooxidant index (API) was calculated from the ratio of catalaseand MDA indices.An increase in lipid peroxidation intensity and a slight decrease in catalase activity in rats with dysbiosis werefound. Consumption of flour from pea straw reduced the intensity of lipid peroxidation, especially in the colon mucosa.It was found that dysbiosis in the digestive system stimulates LPO to a greater extent in organs with low catalase activity.Pea straw flour has antioxidant properties.

Introduction. The process of dehulling grain peas is not enough researched, and there are difficulties of modeling the technological process as a whole. Presented research results of the process of pea seeds dehulling allow to understand the behavior of pea seeds during dehulling in machines with abrasive working members. Materials and methods. Pea seeds of varying large-scale and moisture are scaly in the laboratory dehuller. The products of dehulling were cleaned in the aspiration channel from husk and dust middlings after this process the products were weighed and determined the dehulling index. By changing the moisture content (from 11,6 to 16,6%) and the size of the pea seeds (from 213 to 257 g), the speed of rotation of the working body of the dehuller (from 25 to 41,6 s-1), the duration of processing (from 5 to 25 s) and the coefficient of filling the working chamber (from 0,09 to 0,48) of the machine was presented dependence of the parameters on dehulling efficiency. Results and discussion. It is determined that the increase of processing time, the pea seeds, the speed of the working organs and filling coefficient of the working chamber of the dehuller increase the efficiency of dehulling peas by linear dependence. Increase in the size of pea seeds contributes to increase of efficiency of dehulling mainly due to increase of the yield of small. The increase in the scale of seeds leads to a decrease in the dehulling index. Along with the increasing efficiency of dehulling, increases and yield of trinkets at the expense of the kernel. When the moisture of pea seeds increases, the yield of a fine grits increases comparing to the dehulling of dry pea. Yield of the kernel is directly proportional to the reduction of the yield of undehulling seeds. The yield of a fine grits also has linear dependencies when you change the following parameters. In the process of dehulling reduces the ash content of the kernel, but also decreases the ash content and husk and dust middlings, which is the result of transition of low-ash content particles of kernel into the dust middlings. Conclusions. For effective dehulling of pea seeds, it is necessary to carry out dehulling for 10-15 s, filling coefficient of the machine must be not less 0,48. Pea seeds with an absolute mass of 257 g, dehull better than pea seeds with an absolute mass of 213. [ABSTRACT FROM AUTHOR]

In the article the advantages of using grain legumes as protein plant concentrates are analysed, and a comparative analysis of the chemical composition of the pea and the soybean meal is carried out. Besides, the official parameters for different protein products for pig feeding are presented. To determine whether it is possible to introduce protein plant concentrates into compound feed, it is necessary to know their physical properties. So, the physical properties of the protein plant concentrates have been investigated for the following parameters: moisture content, bulk density, angle of repose, and flowability. Methods of introducing protein plant concentrates into compound feeds have been developed and presented. Taking into account the physical properties and norms of introducing protein plant concentrates for farm animals and poultry, a scheme has been developed for a technological line preparing a portion of grain, powdery, mineral raw materials and meals. One of the methods of introducing protein plant concentrates into compound feeds is extrusion. That is why, a technological scheme of an extrusion line for grain legumes has been developed. The technological scheme provides for the extrusion of a soybeans and peas mixture in the ratio 1:1. Also, the physical properties of the extruded feed additive have been studied. With the software package “Korm Optima Expert,” recipes for feeding piglets aged 43-60 days have been calculated (with protein plant concentrates used in the recipes), and some feeds of animal origin have been replaced with extruded feed additives. According to the calculated recipes, an experimental batch of mixed feeds with the use of protein plant concentrates has been manufactured, and its physical properties have been determined.
