Современный рынок молочной продукции претерпевает существенные изменения, в основе которых лежит тенденция на удешевление продукции. Российские молочные продукты, произведенные из классического сырья по традиционным технологиям, зачастую подвергаются фальсификации продуктами с пониженными массовыми долями жира и белка, заменой молочных компонентов и живых заквасочных культур вследствие отсутствия системы идентификационных характеристик. Реформой технического регулирования, проведенной в Российской Федерации в 2000 году, правила идентификации как способ отнесения продукта к определенной группе продукции посредством сопоставления его характеристик с установленными были законодательно закреплены на федеральном уровне. В настоящее время идентификация служит неотъемлемой частью оценки (подтверждения) соответствия продукции и является главным средством борьбы с фальсификацией. Критериями идентификации выступают регламентированные показатели продукта. Технический регламент Таможенного союза 033/2013 «О безопасности молока и молочной продукции» включает понятие «национальный молочный продукт», однако критерии идентификации этой группы продукции отсутствуют. Целью исследования был поиск уникальных характеристик российских молочных продуктов для их идентификации среди аналогичной продукции. В качестве метода был применен ретроспективный анализ литературы с глубиной поиска до 1930-х гг. Установлено, что в качестве критериев идентификации молочных продуктов использовали не только сырьевой и технологический признаки, но и упаковку. Выявленные критерии будут положены в основу формирования системы идентификации российских молочных продуктов. The modern dairy market is undergoing significant changes, which are based on the trend towards cheaper products. Russian dairy products made from classical raw materials using traditional technologies are often falsified by products with reduced mass fractions of fat and protein, replacing dairy components and live starter cultures due to the lack of an identification system. The reform of technical regulation carried out in the Russian Federation in 2000, the identification rules as a way of classifying a product as a specific product group by comparing the characteristics with the established ones were legally fixed at the federal level. Currently, identification is an integral part of the assessment (confirmation) of product conformity and is the main means of combating falsification. Identification criteria are regulated product indicators. The technical regulation of the Customs Union 033/2013 «On the safety of milk and dairy products” includes such a concept as «national dairy product», however, there are no criteria for identifying this group of products. The aim of the research was to search for unique characteristics of Russian dairy products and classical technologies that distinguish them from similar products. As a method, a retrospective analysis of the literature with a search depth of up to the 1930s was used. It was established that not only raw and technological characteristics, but also packaging were used as criteria for identifying dairy products. The identified criteria will be the basis for the formation of an identification system for Russian dairy products.

The current market of low-alcohol beverages has been evaluated. The production of alcohol-free beverages is characterized by an extremely wide variety of raw materials. It is allowed to use juices, concentrates, infusions, and extracts of vegetable raw materials, flavours, emulsions, aromatic bases, food acids, vitamins, colourants, stabilizers, preservatives, clarifiers, opacifiers, sweeteners, and other raw materials that meet the requirements of regulations in effect and are authorized by the Ministry of Health. It has been established that the use of natural vegetable raw materials, which are a source of biologically active substances, will help increase the demand for these beverages. As such raw material, it has been suggested to use sugar sorghum, which is a promising agricultural crop and is characterized by a rich component composition. It has been suggested to obtain low-alcohol beverages by wort fermentationon on the basis of sugar sorghum juice, with the addition of apple and apple-cherry concentrates. The physicochemical parameters of the wort have been determined, and suggested the modes of its fermentation with dry yeast from the manufacturers Biowin (Brewgo-01) and Fermivin (Gervin GV1), related to brewing and wine yeast races, respectively. The influence of these yeasts on the accumulation of fermentation by-products and on the formation of organoleptic characteristics of beverages has been investigated. It has been found that in the samples studied, most of the fermentation by-products are in quantities close to the perception threshold, and, certainly, they affect the taste and aroma profile of the finished beverages. The profile charts of taste and aroma have been constructed, and the conclusion has been drawn about the prospects of using sugar sorghum juice in the low-alcohol beverages technology based on natural raw materials.

The article provides the results of studies on the influence of temperature conditions of milk fermentation in the manufacture of yogurt on the characteristics of milk clots and the level of EPS production. The characteristics of the samples of reconstituted skim milk fermented by consortia of lactic acid microorganisms for the manufacture of starter and viscous consistency yoghurt starter cultures under temperature conditions are determined: (43 ± 1)°С, (38 ± 1)°С, (35 ± 1)°С and ( 30 ± 1)°С. It was noted that with a decrease in the fermentation temperature from (43±1)°C to (30±1)°С, the organoleptic characteristics of the formed clot are evaluated differently. At the fermentation temperature of (30±1)°С, the lowest degree of syneresis was noted: 45% for the consortium, during the fermentation of milk raw materials forming clumps of inviscid consistency, 29% for the consortium, during the fermentation of milk raw materials forming clumps of viscous consistency. At the same time, it was found that at fermentation temperatures of (43±1)°С and (30±1)°С, the highest level of EPS synthesis for consortia was noted: (2107 ST-A+2674 TL-AV) – 874.6 and 667.9 μg / ml, (1141 ST-AV+2674 TLAV) – 683.9 and 541.3 μg / ml.

The significance of the paper is confirmed by the need to replace petroleum motor fuels with fuels produced from alternative energy sources. Biofuels derived from various vegetable resources are considered as promising alternative fuels for diesel engines. These fuels offer significant advantages with respect to the renewability of their raw materials and good emission performances when burned in ICEs. The main problem of using vegetable oils as biofuels for diesel engines is their high viscosity. This problem can be resolved by using mixed biofuels with the addition of gasoline. The analysis of physico-chemical properties of petroleum diesel fuel (DF) and mixed biofuels containing petroleum DF, rapeseed oil (RO) and AI-80 automotive gasoline was conducted. Experimental studies of the D-245.12S diesel fuelled with these mixed fuels were carried out. The mixed fuels were prepared from 80% DF + 20% RO, from 75% DF + 20% RO + 5% AI-80, and from 70% DF + 20% RO + 10% AI-80. It was shown that the addition of gasoline to mixed biofuels could improve two main toxicity indicators of exhaust gases exhaust gases smoke and emissions of nitrogen oxides. The best emission performance was achieved for the mixture of 70% DF, 20% RO and 10% AI-80. When the diesel engine was switched from the mixture of 80% DF and 20% RO to the mixture of 70% DF, 20% RO and 10% AI-80, the exhaust gases smoke at maximum torque mode decreased from 17.5 to 14.5% on the Hartridge scale, i.e. by 17.1%. The specific emissions of nitrogen oxides decreased from 6.559 to 6.154 g/(kW·h), i.e. by 6.2%.

Nowadays in the dairy industry, the combination of raw materials of plant origin with a dairy base can be noted. Received dairy products have a functional orientation. The product line is expanding with every new filler. This allows the consumers to choose the product they like. The properties of the starter cultures used for fermented milk products were studied by the authors, and the choice of starter culture was carried out. The starter culture “Narine” was used in the development of a method for the fermented milk drink production. The choice of starter culture was made taking into account the more pronounced bactericidal antibiotic properties of acidophilus bacillus in relation to some harmful and pathogenic bacteria compared to other starter cultures. The choice of flavor component was carried out to expand the assortment of fermented milk drink. Experiments showed that yellow and orange colors affect the perception of the buyer positively. They help to cope with fatigue and depression. They are closer to the natural colors of dairy products; therefore, in the production of this fermented milk drink, the orange filler in the form of syrup was used. Mass fraction of orange syrup ranged from 1 to 7%. The optimal dosage was 5%. With the help of it the drink had a clean sour-milk taste and the orange smell, a uniform consistency and a yellowish color. The recipe was selected and the technology of fermented milk drink, which involves the introduction of orange syrup in the fermented product, was developed. The main organoleptic, physico-chemical and microbiological indicators of the fortified fermented milk drink were studied in the work. The compliance of the quality indicators of the fermented milk drink with the requirements of the Technical Regulations of the Customs Union “On the Safety of Milk and Dairy Products” (TR TS 033/2013) was determined.

Underground Valerian roots (Vаlеrіаnае radix) are officinal raw materials. More than 1000 compounds were detected in Valeriana officinalis L. s.l., of which no less than 500 natural substances of organic and inorganic origin were identified, among them – carbohydrates, amino acids, lipids, vitamins, enzymes, phenolic compounds, essential oil, iridoids, alkaloids, steroids. The aerial part of Valerian is a source of various flavonoids with pronounced antioxidant properties and specific pharmacotherapeutic activity. The aim of the research is to determine, by means of gas chromatography, component composition of Valerian tinctures, made of the aerial part of V. tuberosa L., V. stolonifera Czern (Kantserivska balka, Zaporizhzhia region, Ukraine) and V. officinalis L. (Łódź, Bydgoszcz, Poland). Materials and methods. Tincture samples of the aerial part of wild species V. tuberosa L., V. stolonifera Czern (Kantserivska balka, Zaporizhzhia region), and V. officinalis L. (the experimental site of ZSMU; Łódź and Bydgoszcz in Poland) were selected for experimental studies according to the traditional production recipe for making tinctures (1 : 5). Component composition of the tinctures was studied using a 7890B gas chromatograph with a 5977B mass spectrometer detector. Results. By means of chromato-mass spectrometry, component composition of the Valerian tinctures has been identified, namely: in the tincture prepared from the aerial part of V. officinalis (Łódź, Poland) 54 components have been identified, V. tuberosa – 50; V. stolonifera – 46 and V. officinalis (Bydgoszcz, Poland) – 30. The chromatogram analysis of four Valerian tinctures helped to identify 118 components, 5 of which were present in all studied tinctures; 12 components were present in three tinctures; 22 components have been found in two tinctures. It should be noted that 10 components have been found in the tinctures in large quantities, their content ranging from 10.91 % to 30.02 %. Conclusions. Analyzing the obtained data of the GC, it can be seen that Valerian tinctures differ both in quantitative and qualitative composition. From the aerial part of Valeriana officinalis, prepared in Łódź and Bydgoszcz in Poland, 17 components coincide. In the tinctures, prepared from herbs collected in Ukraine, 10 components coincide. The highest content of Butanoic acid, 3-methyl – from 4.01 % to 16.78 %; 9,12,15-Octadecatrienoic acid, ethyl ester, (Z,Z,Z)- – from 0.47 % to 7.09 %; Dihydroxyacetone – from 0.37 % to 5.69 % and Quinic acid – from 0.30 % to 4.66 % in all four tinctures by peak areas and retention time should be marked. In three tinctures Cyclododecane, 1,5,9-tris(acetoxy)- has been identified in amount of 30.56 % to 14.56 %. The obtained results confirm the expediency of using the aerial part of Valeriana officinalis as raw material with a large commodity yield and various contents of biologically active substances for further pharmacognostic researches for the purpose of creation of new medicines and phytopreparations

One of the most important areas of internal combustion engine improvement is its adaptation to work on alternative fuels. Motor fuels obtained from renewable plant raw materials are considered to be promising alternative fuels. The article considers the possibility of using soybean oil as an ecological additive in petroleum diesel fuel. The features of soybean oil production and the physico-chemical properties of soybean oil and a mixture containing 80 % (by volume) of petroleum diesel fuel and 20 % of soybean oil are researched. Computational studies of the processes of fuel atomization and mixture formation in the D-245 diesel engine operating on mixtures of petroleum diesel fuel and seed oil have been performed. Experimental studies of the D-245 diesel engine operating on petroleum diesel fuel and the specified blended fuel have been carried out. Conversion of a diesel engine from petroleum fuel to mixed one leads to a decrease in integral emissions per test cycle: nitrogen oxides by 19.1 %, carbon monoxide — by 10.5 %, unburned hydrocarbons - by 8.9 %.
