Traditionally, the composition of sauces includes wheat flour, vegetables, spices. Nowadays powdered plant compositions of polysaccharides (PS), such as locust bean gum and guarana, have gained wide popularity. Based on the organoleptic studies performed, samples of milk sauce with the addition of guarana in concentrations of 0.5 and 1.0 % have been selected, which have been compared with a control sample made using wheat flour. The introduction of 0.5 % guarana into the composition of the milk sauce does not change the level of the mass fraction of fat in the sample, and the addition of 1.0 % guarana has increased the mass fraction of fat by 2.05 times compared to the control. Replacing wheat flour with a polysaccharide in the studied samples with the addition of guarana at concentrations of 0.5 and 1.0 % has reduced the level of mass fraction of solids by 8.3 and 7.9 % and titratable acidity by 3.6 and 5 °T, respectively. According to generally accepted microbiological indicators, prototypes of milk sauce with guarana correspond to regulatory documentation. In the developed sauces, the content of proteins has decreased by 22.19 %, fats – by 2.46 %, carbohydrates – by 54.76 %, which led to a decrease in energy value by an average of 32.16 %. Thus, milk sauce with the addition of guarana can be recommended as a dietary product for preventing obesity, improving lipid metabolism, and lowering cholesterol levels. In the course of determining the economic efficiency of introducing milk sauce with guarana into production, it has been found that the profit amounted to 9628.26 thousand rubles with an annual production capacity of 677.76 tons per year.","PeriodicalId":30200,"journal":{"name":"Vestnik MGTU","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135295216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beet sugar production is a source of a number of by-products such as beet pulp, molasses and filter cake. Domestic sugar production refers to material-intensive industries, since the volume of vegetable raw materials, as well as by-products formed in the technological process, is several times higher than the yield of finished products – white sugar. Insufficient attention to the problems of more complete processing of by-products of sugar beet production may be the cause of environmental degradation. Currently, not only the regulatory documentation regulating the quality indicators of raw materials used and finished products of the industry has been updated, but also the definition of by-products of sugar production, formed in the production of white sugar, has been clarified. In particular, by-products of the sugar beet industry can be used to extract useful components from them, suitable for the production of new food products with increased nutritional value. The main attention in the paper is paid to promising areas for the use of beet pulp for the production of new types of food products. A method has been developed for the production of sugar syrup enriched with pectin extract of beet pulp. The addition of beet pulp pectin extract to the syrup not only increases the nutritional value, but also improves its technological properties while expanding the range of new types of food products and their properties.","PeriodicalId":30200,"journal":{"name":"Vestnik MGTU","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135295325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The physico-chemical properties causing antimicrobial properties include: cationic charge, hydrophobicity, molecular weight and amino acid sequence. Promising sources of antimicrobial peptides are milk proteins, in particular, cow colostrum proteins. The aim of the work is to extract a peptide from the pepsin hydrolysate of cow colostrum, predict its antimicrobial activity using a bioinformatic approach and confirm its effectiveness in vitro. The molecular mass distribution of the peptide was evaluated by mass spectrometric method. The analysis of mass spectra was carried out using the Mascot program, the Peptide Fingerprint option – using the Protein NCBI database. Microsequencing was performed using a MiSeq sequencer. Modeling of the spatial structure of the isolated peptide was carried out using the Schrodinger Maestro molecular modeling program. The antimicrobial activity of the peptide was studied by the disco-diffusion method on gram-positive and gram-negative bacteria. The peptide has been isolated from the pepsin hydrolysate of cow colostrum, which is absent in the known proteomic bases Protein NCBI and AVPdb and, accordingly, its biological activity and functions have not been studied. The resulting peptide belongs to linear alpha-helical peptides consists of 11 amino acid sequences ANRKLRANKSR with a molecular weight of 8.2 kDa, an isoelectric point at 12.79, a charge of +5 (cationic), hydrophilicity (hydrophobicity) +20.84 Kcal*mol-1.

Nitrogen can enter quarry effluent when explosives containing ammonium nitrate are used in blasting operations. This nitrogen pollution of water leads to environmental damage and human disease, companies that exceed the legal limits for nitrogen pollution are subject to fines. Nitrogen is removed from wastewater by biological methods, but their efficiency is low in the Northern regions of Russia due to climatic factors that hinder the vital activity of organisms. Therefore, it is essential to develop wastewater treatment technologies for the removal of nitrogen compounds. This study focuses on the ability of the microalgae Chlorella vulgaris to absorb and utilize various inorganic nitrogen compounds in mining effluents using the example of effluents from the \"Karelsky Okatysh\" mine and tailings dam (Kostomuksha, Republic of Karelia). Concentrations of ammonium, nitrate and nitrite in water and microalgal biomass in water samples have been investigated. A novelty of the study is the evaluation of pollutant concentrations in parallel experiments with different cultivation conditions. It has been found that when Chlorella vulgaris is cultivated at 26 °C, aeration and artificial light, the concentration of ammonium decreases. These results show the promising application of bioreactor technologies for the treatment of ammonium polluted wastewater.","PeriodicalId":30200,"journal":{"name":"Vestnik MGTU","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42216767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Russian waters of the Japan Sea, regular study of its biology was conducted in the waters of the Primorsky Krai, where annual trawl surveys were performed.

Endogenous rhythms (internal biological clocks) play a crucial role in the coordination of biorhythms of the Arabesque greenling Pleurogrammus azonus. This assumption is confirmed by the different duration of exogenous and endogenous rhythms: the dynamics of the temperature index has a pronounced periodization equal to one astronomical year, and the duration of the mixed rhythms in the dynamics of physiological processes and main components changes with age. The relationship of somatic and generative growth with temperature oscillation is subjected to age-related variability. In juveniles, this relationship is not clearly traceable. At the beginning of puberty period, significant connections are manifested. Then the dependence of growth indicators on the temperature oscillation is reduced, as the selective ability of the Arabesque greenling to choose the temperature range increases. Selective ability to environmental conditions is largely determined not by individual but by group behavior.","PeriodicalId":30200,"journal":{"name":"Vestnik MGTU","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44719008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The size and age parameters of two populations of the narrow-clawed crayfish Pontastacus leptodactylus in the Loktyshi (Brest Region) and Krasnoslobodskoe (Minsk Region) reservoirs in Belarus have been compared. The Krasnoslobodskoye reservoir is intensively exploited with an annual catch of 3–4 tons of crayfish. There is no commercial fishing in the Loktyshi reservoir. Studies show that the average size of individuals in an intensively exploited population is smaller in comparison with a population where there is no commercial fishing for crayfish. Since crayfish fishing is regulated by a commercial measure (10.5 cm of total length) in intensively exploited populations, the average sizes of individuals are close to these limiting values. The life expectancy of crayfish is somewhat higher in the Loktyshi reservoir, where only amateur crayfish fishing is noted. Intensive fishing increases the mortality of females, whose annual survival rate is 37 %, while in the absence of fishing, the survival of females increases up to 57 %. The annual survival rate of males is 41–49 %. The fishing pressure leads to decrease in the survival rate of individuals and disappearance of crayfish aged 9–10 years from the population.","PeriodicalId":30200,"journal":{"name":"Vestnik MGTU","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48012981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under such conditions, it is necessary to assess the impact hazard of ores and rocks that make up the mined deposits. For the prompt implementation of such an assessment, it is proposed to use the Kaiser criterion consisting in the analysis of experimental data obtained on rock samples. The paper presents the results of laboratory testing of rock samples from the deposits of the Khibiny massif under uniaxial compression and tension. The values of their brittleness coefficients have been determined. The possibility of using the Kaiser criterion for a preliminary assessment of rock burst hazard potential has been shown. It has been established that spotty-trachytoid melteigite and trachytoid ijolite-melteigite have a high potential for impact hazard, while spotted apatite-nepheline ore does not have such a potential. A comparison has been made of the obtained results of rockburst hazard assessment of hard rocks from the Khibiny massif deposits according to the Kaiser criterion, as well as the criterion of the Mining Institute of the KSC RAS and the criterion of A. N. Stavrogin. It can be noted that the Kaiser criterion makes it quite easy to carry out a preliminary assessment of rock burst hazard based on the results of testing samples on standard presses. However, to increase the degree of reliability of the data obtained, they must be certified according to the criterion of the Mining Institute of the KSC RAS or the criterion of A. N.
