According to the Decree of the President of the Russian Federation of January 21, 2020 N 20 "On the approval of the Doctrine of food security of the Russian Federation", the basis for the formation of a national quality management system for food and agricultural products, the main goal of which is to ensure product quality as the most important component of improving health population, improving the quality of agricultural products with the help of modern innovative technologies and feed additives, promoting and stimulating the growth of demand and supply for better food products and ensuring the observance of consumer rights to purchase quality products. Achieving the goals of the Doctrine in the field of improving the quality of food and feed products is supposed to be realized with the help of some tasks, where one of them is the development of the production of food additives and ingredients in the Russian Federation, as well as the development and implementation of a quality management system for agricultural and food products and the creation of conditions for production of new generation products with specified quality characteristics. In this regard, this paper discusses the optimal and economical methods for extracting the dye from the flowers of Clitoria ternatea in order to reduce the duration of the production cycle and the introduction of low-waste technologies, which can exclude the irrational use of raw materials, lead to an increase in production, a decrease in the cost of the finished product, and an increase in economic production indicators, reducing the anthropogenic impact of production on the environment. Also, the work has developed and described a modern technology for the production of a dye, according to which it is possible to improve the quality and safety monitoring system. The prospects of using the dye from Clitoria ternatea flowers in feed additives for farm animals and birds are considered. This can undoubtedly be of interest to the business community, therefore, we can assume that the production of a natural dye from plant materials and this work is a fairly relevant subject within the framework of the Doctrine of Food Security of the Russian Federation, not only from the medico-biological, but also from the technological side.
根据2020年1月21日俄罗斯联邦总统令“关于批准俄罗斯联邦粮食安全原则”,这是形成国家食品和农产品质量管理体系的基础,其主要目标是确保产品质量,作为改善人口健康的最重要组成部分,利用现代创新技术和饲料添加剂提高农产品质量,促进和刺激优质食品需求和供给的增长,保障消费者购买优质产品的权利。实现目标的学说领域的改善食品和饲料产品的质量应该是用一些任务的帮助来实现,其中一个在哪里生产食品添加剂和配料的发展在俄罗斯联邦,以及开发和实现农业与食品产品的质量管理体系和创造条件生产指定的新一代产品质量特征。为此,本文探讨了从阴蒂花中提取染料的最优、最经济的方法,以缩短生产周期,并引入低废工艺,排除原料的不合理使用,提高产量,降低成品成本,提高经济生产指标,减少生产对环境的人为影响。此外,这项工作还开发并描述了一种生产染料的现代技术,根据这种技术,可以改进质量和安全监测系统。展望了阴蒂花染料在畜禽饲料添加剂中的应用前景。这无疑会引起商业界的兴趣,因此,我们可以假设,从植物材料生产天然染料,这项工作在俄罗斯联邦粮食安全原则的框架内是一个相当相关的主题,不仅从医学-生物学方面,而且从技术方面。

The increasing relevance in the field of repair and restoration of machines and mechanisms is acquiring gas-thermal methods of applying functional coatings to the working surfaces of parts of machine assemblies. The purpose of gas-thermal coating methods is to provide and obtain special physical and mechanical properties of the surface of the part, as well as to restore worn-out components and mechanisms after their long-term and intensive operation. Plasma spraying of composite coatings is an effective method of gas-thermal treatment of the surface of a part. In this paper, a study was conducted on the optimal selection of material for plasma spraying of a part, taking into account its operational features and types of wear of working surfaces. In particular, the operating conditions of the screw of the conveying conveyor are analyzed. The technological features of the application of composite materials by plasma spraying technology are considered. The theoretical selection of a two-phase dispersed-filled composite for application to the working surfaces of the screw in order to restore and harden it has been carried out. Studies and analysis of one of the main indicators of the quality of the formed coating after plasma spraying – the magnitude of the resulting residual stresses (stretching and compression) have been carried out. Taking as a basis the kinematic modes and geometry features of the working surfaces of the screw, as well as the criteria for the formation of the thickness of the sprayed layer, the calculation equations for determining the residual stresses arising on the screw and cylindrical surfaces of the screw of the conveying conveyor are obtained. It is concluded that in order to achieve the required physical and mechanical properties of the coating, the volume fraction of the filler in the matrix of the PG-SR4 composite powder should be in the range of 20–25%. Therefore, it is possible to use in practice a particulate-filled composite of the NiСrВSiFе type with 20–25% reinforcing TiC filler particles in order to restore parts of machines and mechanisms.
在机器和机构的维修和修复领域,越来越多的相关性是获得将功能涂层应用于机器组件部件工作表面的气热方法。气热镀膜方法的目的是提供和获得零件表面的特殊物理和机械性能,以及恢复长期密集运行后磨损的部件和机构。等离子喷涂复合涂层是零件表面气热处理的一种有效方法。本文结合某零件的工作特点和工作表面的磨损类型,对其等离子喷涂材料的优化选择进行了研究。重点分析了输送输送机螺杆的运行工况。分析了等离子喷涂技术应用于复合材料的工艺特点。对螺杆工作表面的两相分散填充复合材料进行了理论选择,使螺杆工作表面得到恢复和硬化。对等离子喷涂后成形涂层质量的主要指标之一——残余应力(拉伸和压缩)的大小进行了研究和分析。以螺杆工作表面的运动模式和几何特征以及喷射层厚度形成的判据为基础,得到了确定输送输送机螺杆和螺杆圆柱表面残余应力的计算公式。结果表明,为获得镀层所需的物理力学性能,填料在PG-SR4复合粉末基体中的体积分数应在20 ~ 25%之间。因此,有可能在实践中使用含有20-25%增强TiC填充颗粒的NiСrВSiFе型颗粒填充复合材料,以恢复机器和机构的部件。

The results of the formation of emulsions of a biologically active additive - wheat germ oil in a defatted fermented milk medium fermented by a consortium of probiotic microorganisms B. bifidum, B. longum, B. adolescentis, L. casei, L. rhamnosus, L. acidophilus, L. plantarum, L. fermentum. The dispersion medium contained at least 109 CFU in 1 g, the pH was 3.65-4.75, the titratable acidity was 120-130oT. The possibility of obtaining stable emulsions with a concentration of wheat germ oil up to 50% is shown. An increase in the capacity and stability of emulsions was established in 1.1-5.9, 1.3-10.6, 1.5-4.0, 1.7-4.7, 1.3-9.7, 1.2 -5.1 when introduced into the dispersion medium 0.5-3.5% of egg white, xanthan gum, egg powder, lecithin, guar gum, skimmed milk powder, respectively. The effect of the speed of rotation of the working body of the emulsifier in the range of 1000-3000 rpm on the emulsifying ability of the dispersion medium and the sedimentation stability of emulsions has been established. An approximating dependence of the emulsifying ability on the concentration of the emulsifier was obtained, taking into account the linear, quadratic and cubic influence of the factor. The results obtained provide a scientific basis for the process of obtaining biologically highly active probiotic emulsions based on wheat germ oil for the alimentary correction of metabolic processes in the human body. High emulsifying ability and sedimentation stability are ensured by the additional introduction of emulsifying substances into the fermented dispersion medium. The resulting emulsions had high organoleptic properties, have a more pronounced biocorrective effect on a number of important body functions, due to the combination of MZP with lacto- and bifidobacteria.

In recent decades, there has been a growing scientific interest in various kinds of technologies using electro-activated solutions with high reactivity and representing a powerful toolkit for intensification of production processes. However, theoretical knowledge about the regularities of change in fat properties during melting in an electrolyte is rather fragmentary, scarce and often contradictory. The work is devoted to the study of the main factors influencing the change in physical and chemical properties and yield of fat in the process of melting using catholyte, to substantiate the feasibility of its use and develop an industrial line for obtaining fat. The object of studies was ostrich fat obtained by traditional method – by melting in water and by experimental technology – in catholyte as well as technological regimes of fat extraction. According to the data obtained, the fat melted at pH of catholyte 11, temperature 100 and 75 °С was characterized by low values of acid number – 0,45 mg KOH/g and 0,40 mg KOH/g, respectively. The opposite trend was observed with a successive decrease in the alkalinity of the ECA medium and an increase in the melting temperature of the fat, which led to an increase in the content of secondary oxidation products in the experimental samples. It was found that due to the high reactivity of the EСA medium, the temperature and pH of the catholyte increased, the intermolecular interaction within the fat phase decreased, which increased the mobility of lipid molecules relative to each other. The lowest values of fat viscosity (0,42 and 0,4 kPa?s) were recorded when treating fatty raw materials in catholyte with pH 10.5 and 11 and temperature 100 °С. It is shown that increasing the pH of the catholyte contributes to minimizing the values of peroxide number of ostrich fat, in contrast to the heating temperature. It is established that processing of raw materials in catholyte at 75 °C resulted in the yield of fat 88,4–90,1%, which is almost 1,4 times higher than when melted in water. In the wet method of mellowing in water, denaturation of protein structures and a higher degree of fat extraction can be achieved at a mellowing temperature above 75 °C, in contrast to the proposed method of processing raw materials.
近几十年来,人们对使用具有高反应性的电活化溶液的各种技术越来越感兴趣,这些技术代表了强化生产过程的强大工具包。然而,关于在电解质中熔化过程中脂肪性质变化规律的理论知识是相当零碎的,稀缺的,而且经常是相互矛盾的。本文致力于研究利用阴极液熔融过程中影响脂肪理化性质变化和得率的主要因素,以证实其使用的可行性,并建立一条获得脂肪的工业生产线。本研究以传统方法(水溶法和实验技术)在阴极液中提取的鸵鸟脂肪为研究对象,以及脂肪提取的工艺制度。结果表明,在pH = 11、温度= 100和温度= 75°С下熔化的脂肪酸值较低,分别为0.45 mg KOH/g和0.40 mg KOH/g。相反的趋势是,ECA介质的碱度连续下降,脂肪的熔化温度升高,导致实验样品中二次氧化产物的含量增加。研究发现,由于EСA介质的高反应性,阴极电解质的温度和pH升高,脂肪相内分子间相互作用减少,从而增加了脂质分子相对于其他分子的流动性。在pH为10.5和11、温度为100°С的阴极电解液中处理脂肪原料时,脂肪粘度最低(0,42和0,4 kPa?s)。结果表明,与加热温度相反,提高阴极电解质的pH值有助于使鸵鸟脂肪的过氧化值最小化。结果表明,在75℃的阴极电解液中加工原料,脂肪得率为88,4 - 90,1%,比在水中熔化时高1.4倍。在水中软化的湿法中,与所提出的加工原料的方法相比,在75℃以上的软化温度下可以实现蛋白质结构的变性和更高程度的脂肪提取。

The possibility of using unsaturated phthalates obtained by the esterification of phthalic anhydride with distillation residues of butyl alcohols as a basis for the synthesis of a bromine-containing plasticizer-fire retardant was evaluated. prene, polyvinyl chloride, and polyvinyl acetate. Instability of the content of unsaturated esters of phthalic acid in the test object was noted with the most probable range of fluctuations in iodine number, ranging from 24.4 to 44.4. A direct dependence of the indicated variation limits on the content of 2-ethylhexene-3-ol-1 in the distillation residue of butanol in the amount of 9.0-17.5% and 2-ethylhexen-2-ol in the amount of 35-43% was established. The ratio of unsaturated esters of 2-ethylhexyl-2-ethylhexene-3-phthalate and 2-ethylhexyl-2-ethylhexene-2-phthalate in an unsaturated plasticizer is 1: 2 ÷ 5. It has been shown that with a shortage in production of a brominated plasticizer with a low bromine content, its required amount can be obtained by diluting a brominated plasticizer with a high bromine content. Dioctyl phthalate and the investigated unsaturated plasticizer were proposed as diluents. It is noted that with incomplete bromination of an unsaturated base, unsaturated esters do not adversely affect the quality of the compositions, make the bromine-containing system more reactive, which leads to additional crosslinking of polymer molecules and an increase in the strength of the composition. It is shown that the modification of an unsaturated plasticizer by bromination will make it possible to obtain a triple effect of inhibition of the combustion process due to the elimination of hydrogen bromide from brominated ethers, an increase in the duration of its elimination and the ability of unsaturated ethers to react with active radicals released during thermal decomposition and combustion of polymer compositions.
探讨了利用邻苯二酸酐与丁醇蒸馏残渣酯化反应得到的不饱和邻苯二甲酸酯为基础合成含溴增塑剂-阻燃剂的可能性。聚乙烯,聚氯乙烯和聚醋酸乙烯。注意到测试对象中邻苯二甲酸不饱和酯含量的不稳定性,碘值的最可能波动范围为24.4至44.4。丁醇蒸馏残渣中2-乙基己烯-3-醇-1含量为9.0% ~ 17.5%,2-乙基己烯-2-醇含量为35 ~ 43%,建立了指示变化限。不饱和增塑剂中2-乙基己基-2-乙基己烯-3-邻苯二甲酸酯和2-乙基己基-2-乙基己烯-2-邻苯二甲酸酯的不饱和酯的比例为1:2 ÷ 5。研究表明,在低溴含量的溴化增塑剂生产短缺的情况下,可以通过稀释高溴含量的溴化增塑剂来获得所需的量。提出了邻苯二甲酸二辛酯和所研究的不饱和增塑剂作为稀释剂。值得注意的是,在不饱和碱不完全溴化的情况下,不饱和酯不会对组合物的质量产生不利影响,而是使含溴体系更具反应性,从而导致聚合物分子的额外交联和组合物强度的增加。结果表明,溴化改性不饱和增塑剂可以获得抑制燃烧过程的三重效果,因为溴化醚中溴化氢的消除,溴化氢消除的持续时间增加,不饱和醚与聚合物组合物热分解和燃烧过程中释放的活性自由基反应的能力增强。

It has been shown that with a shortage in production of a brominated plasticizer with a low bromine content, its required amount can be obtained by diluting a brominated plasticizer with a high bromine content. Dioctyl phthalate and the investigated unsaturated plasticizer were proposed as diluents. It is noted that with incomplete bromination of an unsaturated base, unsaturated esters do not adversely affect the quality of the compositions, make the bromine-containing system more reactive, which leads to additional crosslinking of polymer molecules and an increase in the strength of the composition. It is shown that the modification of an unsaturated plasticizer by bromination will make it possible to obtain a triple effect of inhibition of the combustion process due to the elimination of hydrogen bromide from brominated ethers, an increase in the duration of its elimination and the ability of unsaturated ethers to react with active radicals released during thermal decomposition and combustion of polymer compositions.","PeriodicalId":20611,"journal":{"name":"Proceedings of the Voronezh State University of Engineering Technologies","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83254443","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 paper proposes an engineering calculation method, on the basis of which it was proposed to use three ultrafiltration units connected in series for the ultrafiltration separation of cheese whey components. These installations operated in a continuous cycle, which contained membrane devices with the calculated parameters. This paper describes a scheme for obtaining whey protein concentrate from cheese whey formed during the processing of milk into rennet cheese. The scheme works on a tubular ultrafiltration apparatus - it was accepted for development at ChS VERO LLC. In our proposed scheme, an electrodialysis unit is used, since this unit has more advantages than others. The advantage of the electrodialysis unit is the demineralization of technological solutions with a high dry matter content (concentrated whey, gelatin, sugar syrup, chicory syrup, glycerin) and tolerance. The productivity of the selected electrodialysis plant allows the concentrated volume to be brought to a demineralization level of 80% in about 1 hour. The work describes in detail the scheme of the concentration line for LLC "VEKSHA" and LLC "ChS" VERO "with obtaining dry whey concentrate, including a tube-type ultrafiltration apparatus. Also substantiated is the value determined by the ratio of the results of production and labor costs and funds for the production of cheese whey for LLC "ChS" VERO "and LLC" VEKSHA ". The expected economic effect from the introduction of the line will be 4200 thousand rubles. for LLC "VEKSHA" and 980 thousand rubles. for LLC "ChS" VERO "per year in prices of 2021.
本文提出了一种工程计算方法,在此基础上提出了采用串联的三个超滤单元进行奶酪乳清组分的超滤分离。这些装置在一个连续循环中运行,其中包含具有计算参数的膜装置。本文介绍了一种从牛奶加工成凝乳酶奶酪过程中产生的奶酪乳清中提取浓缩乳清蛋白的方案。该方案适用于管式超滤装置-它已被ChS VERO LLC接受用于开发。在我们提出的方案中,使用电渗析装置,因为该装置比其他装置具有更多优势。电渗析装置的优点是对高干物质含量(浓缩乳清、明胶、糖浆、菊苣糖浆、甘油)和耐受性的工艺溶液进行脱矿。所选电渗析厂的生产率允许浓缩体积在约1小时内达到80%的脱矿水平。详细介绍了LLC“VEKSHA”和LLC“ChS”VERO浓缩线的方案,包括一个管式超滤装置,用于获得干乳清精矿。同样得到证实的是,为LLC“ChS”VERO和LLC“VEKSHA”生产奶酪乳清的生产结果与劳动力成本和资金的比例决定的价值。该生产线的引入预计将带来420万卢布的经济效益。“VEKSHA”有限责任公司和98万卢布。LLC“ChS”VERO每年的价格为2021年。

Titanium is among the most demanded metals by high-tech industries. In Russia, imported raw materials are used for its production. At the same time, a new promising type of gold-ilmenite ores and placers associated with ultrabasite intrusions has been discovered in the south of the Far East. On the example of one of these objects, the Ariadne ore-placer node, the possibilities of creating the foundations of a technology for complex extraction of useful components from titanium-bearing placers using pyro-hydrometallurgy techniques are investigated. The objectives of this study were to improve the technological methods of titanium from ilmenite concentrate using ammonium sulfate. It was found that the reactions of the main components of the concentrate with (NH4)2SO4 begin when the temperature of thermal decomposition (NH4)2SO4 (3000C) is reached and proceed with the formation of a mixture of well-soluble in water double salts - ammonium sulfate and iron compositions (NH4)2Fe2 (SO4)3 and NH4Fe(SO4)2 and ammonium sulfate and titanyl composition (NH4)2TiO(SO4)2. It is shown that an increase in the interaction temperature above 3600C leads to the thermal decomposition of the formed double salts to sulfates and then oxides. The experience gained in deep processing of ilmenite mineral raw materials will help to more reasonably outline ways to develop Far Eastern complex deposits in compliance with the principles of rational nature management and environmental protection. Further research should be carried out in the direction of deepening the degree of processing of gold-titanium sands, which will reduce the cost of obtaining individual products and ensure higher production efficiency.
钛是高科技行业需求量最大的金属之一。在俄罗斯,它的生产使用进口原材料。与此同时,在远东南部发现了一种与超基岩侵入体伴生的金钛铁矿、砂矿新类型。以阿里阿德涅矿砂矿节点为例,研究了利用热湿法冶金技术从含钛砂矿中复杂提取有用成分的技术基础的可能性。本研究的目的是改进用硫酸铵从钛铁矿精矿中提取钛的工艺方法。结果表明:当(NH4)2SO4达到热分解温度(3000C)时,精矿主要组分与(NH4)2SO4发生反应,形成易溶于水的双盐——硫酸铵和铁组分(NH4)2Fe2 (SO4)3和NH4Fe(SO4)2与硫酸铵和钛组分(NH4)2TiO(SO4)2的混合物。结果表明,当相互作用温度升高到3600℃以上时,生成的双盐会热分解为硫酸盐和氧化物。在钛铁矿矿物原料深加工方面所取得的经验将有助于更合理地勾勒出按照合理的自然管理和环境保护原则开发远东复杂矿床的途径。进一步研究应朝着深化金钛砂加工程度的方向进行,以降低获得单个产品的成本,保证更高的生产效率。

Fruit and berry mousses used as desserts and cake fillings have low nutritional value due to protein deficiency. Legumes can be used as ingredients for enriching sweet dishes. The aim of the work was to study and substantiate the possibility of using beans seeds in the technology of dessert mousse of increased biological value. The objects of the study were samples of seeds of white beans (Phaseolus vulgaris) and mousses prepared on their basis. This type of beans is constantly presented on the Russian market and is the main one in canning. Investigations were carried out: the chemical composition of bean seeds was determined, a recipe for bean mousse was developed, an analysis of the nutritional value, consumer properties and shelf life of the new product was carried out. Standard laboratory methods of analysis were used. Boiled crushed beans (bean paste) were added to the mousse. In boiled beans, compared to dry seeds, the water content increased from 7.7 to 58.9%, protein decreased from 22.9 to 8.2% (in dry matter 24.8–20.2% ). Based on the analysis of the influence of the amount of beans on the formation of the structure and organoleptic properties of the mousse, the optimal content of beans in the mousse was established - 40%. The developed mousse recipe includes: boiled beans, additional flavoring substances (sugar, fruit or berry juice), a structurant (gelatin), water. Bean mousse is characterized by a high protein content (over 6%) and dietary fiber (over 3%), moderate calorie content (160 kcal/100 g of product), lack of preservatives and flavor enhancers, therefore it can be classified as a healthy food.
由于缺乏蛋白质,用作甜点和蛋糕馅的水果和浆果慕斯营养价值低。豆类可以作为丰富甜食的配料。本研究的目的是研究和证实利用蚕豆种子制作具有更高生物价值的甜点慕斯的可能性。研究对象为白豆(Phaseolus vulgaris)种子样品和在其基础上制备的慕斯。这种类型的豆子经常出现在俄罗斯市场上,是罐装的主要品种。进行了调查:确定了豆种子的化学成分,开发了豆慕斯的配方,对新产品的营养价值、消费者特性和保质期进行了分析。采用标准实验室分析方法。将煮熟的碎豆(豆沙)加入慕斯中。与干种子相比,煮熟的豆子含水量从7.7提高到58.9%,蛋白质含量从22.9%降低到8.2%(干物质含量为24.8 ~ 20.2%)。在分析了豆类用量对慕斯结构形成和感官特性影响的基础上,确定了慕斯中豆类的最佳含量- 40%。开发的慕斯配方包括:煮熟的豆子,额外的调味物质(糖,水果或浆果汁),结构剂(明胶),水。豆丝的特点是蛋白质含量高(6%以上),膳食纤维含量高(3%以上),热量含量适中(160千卡/100克产品),不含防腐剂和增味剂,属于健康食品。

Water-retaining capacity is an essential property for the chemical components of food products, as it refers to one of the characteristics that determine the commercial properties of products. At the same time, there are practically no data on the hydrophilicity of sweeteners in the literature; a specific criterion for assessing this property is not given. Hydrophilicity is typically defined as a techno-functional property, i.e. it is assessed for a certain food product as a whole, when replacing the classic sweetener with another, for example, cheaper. From the literature, the isopiestic method was used to assess the hydrophilicity of isomalt in comparison with sucrose. The article is devoted to choosing a parameter that can become a universal criterion for assessing the water-retaining capacity of sweeteners. The hydrophilicity of erythritol, cyclomate, glucose, sucrose, and sorbitol has been studied by isopiestic method. The gravimetrically determined area S under the isopiestic curve was used as an analytical signal to assess the hydrophilicity of sweeteners. The correlations of S with various criteria, such as the Davis and Griffin criterions, the simplified criterion for hydrophobicity, the integral Gibbs energy, and the solubility of substances in water, for assessing the hydrophilicity (hydrophobicity) of sweeteners are considered. A correlation of the area under the isopiestic curves S only with the integral Gibbs energy from all the considered criteria was shown. The data obtained allow us to recommend the integral Gibbs energy for assessing the hydrophilicity and, consequently, the water-retaining capacity of sweeteners.
保水性是食品化学成分的一项基本特性,它是决定产品商业性能的特性之一。同时,在文献中几乎没有关于甜味剂亲水性的数据;没有给出评估这一特性的具体标准。亲水性通常被定义为一种技术功能特性,即,当用另一种更便宜的甜味剂替代经典甜味剂时,对某种食品的整体亲水性进行评估。从文献中,我们用等静力学的方法来评价异麦芽糖与蔗糖的亲水性。本文致力于选择一个参数,可以成为一个普遍的标准,以评估甜味剂的保水能力。用等静力法研究了赤藓糖醇、环甲酸酯、葡萄糖、蔗糖和山梨糖醇的亲水性。用等静力曲线下的重量测定面积S作为分析信号来评价甜味剂的亲水性。考虑了S与各种标准的相关性,如Davis和Griffin标准、简化的疏水性标准、积分吉布斯能和物质在水中的溶解度,以评估甜味剂的亲水性(疏水性)。显示了等压曲线S下的面积仅与所有考虑的准则的积分吉布斯能量的相关性。获得的数据允许我们推荐积分吉布斯能量来评估亲水性,从而评估甜味剂的保水能力。

The research aimed to justify the production of quark from a normalized mixture with whey protein hydrolysate using Advanced Technology (АТ) and acid coagulation to reduce the allergenicity of the finished product. The whey protein hydrolysate obtained with the help of the enzymes Promod 439L and Flavorpro 766MDP was proposed as a component of normalization and consistency stabilizer because it characterized by reduced allergenicity and a high content of biologically active peptides. The chemical composition of the finished product and its microbiological properties as well as microstructure were determined using standard arbitration and generally accepted research practices. It was found that the replacement of 30% of skimmed milk in the normalized mixture with whey protein hydrolysate has a positive effect on the consistency of the finished product and allows to reduce allergenicity at 50%. The excessive content of hydrophilic whey proteins, as well as peptides, contributes to the formation of consistency and moisture retention inside the dispersed system without syneresis. The experimental sample characterized by high concentration of living cells of starter microorganisms (more than 109CFU/gr) and high survival rate of the starter microflora during the storage (more than 4 times in comparison with the control sample). The additional proteolytic breakdown of milk proteins during the fermentation leads to the reduction of the antigenicity of proteins. The developed curd product can be recommended as part of dietary and general diets as biologically complete product with reduced allergenicity. This approach provides a closed cycle for processing raw materials at dairy enterprises.
该研究旨在证明使用先进技术(АТ)和酸凝法从乳清蛋白水解物的标准化混合物中生产夸克的合理性,以减少成品的致敏性。利用Promod 439L酶和Flavorpro 766MDP酶制备的乳清蛋白水解液具有降低致敏性和高生物活性肽含量的特点,因此被认为是一种归一化和一致性稳定剂。成品的化学成分及其微生物特性以及微观结构是使用标准仲裁和普遍接受的研究实践确定的。研究发现,用乳清蛋白水解物代替标准化混合物中30%的脱脂奶,对成品的稠度有积极影响,并可将致敏性降低50%。亲水性乳清蛋白以及多肽的过量含量有助于在分散系统内形成稠度和水分保持,而没有协同作用。实验样品具有发酵剂微生物活细胞浓度高(大于109CFU/gr)和发酵剂菌群在贮藏过程中存活率高(比对照样品高出4倍以上)的特点。牛奶蛋白在发酵过程中额外的蛋白水解分解导致蛋白质抗原性的降低。开发的凝乳产品可以推荐作为饮食和一般饮食的一部分,作为生物完整的产品,降低了致敏性。这种方法为乳品企业的原料加工提供了一个封闭的循环。
