The article proves how practical it is to use whole-milled millet grain to improve the quality of bakery products. Samples of bread with the addition of different amounts of milled millet grain before and after microwave treatment have been evaluated by sensory (surface, shape, and colour of bread, porosity, structure and colour of the crumb) and physico-chemical parameters. To determine the organoleptic evaluation of bread samples with the addition of 5%, 10%, and 15% whole-milled millet grain before and after microwave treatment, a scoring scale and the profiling method were used. According to the results of the research, the advantages of introducing milled millet grain into wheat flour has been substantiated, and it has been shown that adding it to the formulation of 5–15% improves the organoleptic characteristics of the bread, namely, giving it a harmonious taste and aroma, an attractive colour, a pronounced smell, and a porous structure, comparatively with standard bread made from wheat flour. The best characteristics were observed after whole-milled millet grain that had undergone microwave treatment was added to the flour. When 15% of whole-milled millet grain is added to wheat flour after microwave treatment, there is a slight decrease in the porosity of the bread. So, the introduction of more than 15% of whole-milled millet into the formulation is considered inappropriate. It has been found that the physical-chemical parameters of bread (humidity, acidity, porosity, mass fraction of sugar and fat), when adding whole-milled millet in the amount of 5–15% before and after microwave treatment, practically do not change. The introduction of 5–15% of whole-milled millet grain into the composition of bread recipes allows you to obtain high quality bread, of high nutritional and biological value, which can be recommended for consumption by all social groups, including children, adolescents, and elderly people. These studies can be used in the future in developing a technology of obtaining bakery products of functional purpose with high consumer properties.

Определены физико-химические показатели 12 образцов сухих и полусладких белых и красных столовых вин, выработанных одним предприятием и разлитых в стеклобутылку (СБ), бутылку из полиэтилентерефталата и упаковку «пакет в коробке» (ПВК) в феврале 2018 г. холодным и горячим способами, с целью установления влияния упаковки на изменение органолептического состава и физико-химических показателей столовых вин. Физико-химический анализ и дегустация представленных образцов столовых вин проведены в марте 2018 г. с использованием общепринятых методик. Установлено, что через месяц после розлива в упаковку все опытные образцы соответствовали требованиям действующей нормативной документации на данный вид продукции и обладали оптимальными физико-химическими показателями, кроме образца полусладкого красного вина в СБ, который на момент анализа был подвержен микробиологическому воздействию. Во всех исследованных образцах столовых вин обнаружен 1,2-пропиленгликоль, но его содержание не превышало допустимых норм. По итогам дегустации для сухих столовых вин рекомендован розлив в СБ, поскольку холодный розлив, применяемый при этом виде упаковки, практически не влияет на изменение органолептических характеристик продукта. Для полусладких вин рекомендуется горячий розлив, поскольку он препятствует забраживанию и задушке вина, а розлив в упаковку ПВК позволяет сохранять качество вина. Physico-chemical parameters of 12 samples of dry and semi-sweet white and red table wines produced by one enterprise and poured into a glass bottle (GB), a bottle of polyethylene terephthalate and a bag-in-box in February 2018 by cold and hot methods were determined in order to establish the influence of packaging on the change in the organoleptic composition and physico-chemical characteristics of table wines. Physical and chemical analysis and tasting of the presented samples of table wines were carried out in March 2018 using generally accepted methods. It was found that a month after filling in the package, all prototypes met the requirements of the current regulatory documentation for this type of product and had optimal physico-chemical parameters, except for the sample of semi-sweet red wine in the GB, which at the time of analysis was exposed to microbiological effects. In all the studied samples of table wines 1,2-propylene glycol was found, but its content did not exceed the permissible norms. Following the results of the tasting, bottling in the GB is recommended for dry table wines, since the cold bottling used in this type of packaging practically does not affect the change in the organoleptic characteristics of the product. For sweet wines it is recommended that hot-filling because it prevents fermenting and suffocating wine and bottling in bag-in-box allows to preserve the quality of the wine.

В последние годы все большее внимание уделяется разработке продукции, обогащенной растительными компонентами. Целью данной работы являлось исследование влияния смесей из порошков растительного происхождения на свойства теста и качество готовых изделий (булочной мелочи). В рецептуру изделий добавляли растительные смеси: № 1 - порошок облепихи, жимолости, мелкоплодных яблок и порошок из жмыха тыквы, № 2 - порошок облепихи и мелкоплодных яблок в количестве 10, 15 и 20 % от массы муки по сухому веществу. Смеси составляли из компонентов, взятых в равных количествах. Сравнительная оценка пищевой ценности смесей показала, что в смеси № 1 выше количество пищевых волокон, кальция и фосфора относительно смеси № 2. В смеси № 2 преобладает количество белков, жиров, органических кислот, калия, натрия, марганца и железа. По содержанию витаминов преимущество на стороне смеси № 2, за исключением витаминов В и В. Установили повышение кислотности теста с внесением растительных смесей, что указывает на интенсификацию процесса брожения. Исследование качества готовых изделий показало, что при соответствии физико-химических показателей требованиям технической документации, при дозировках смесей выше 10 % отмечали значительное потемнение цвета изделий, появление растительного привкуса, а в изделиях с добавлением смеси №1 неприятное послевкусие. Наиболее рациональной для производства хлебобулочных изделий повышенной пищевой ценности для здорового питания признана рецептура с использованием растительной смеси № 2 из порошков облепихи и мелкоплодных яблок в количестве 10 % к массе муки. In recent years, more and more attention has been paid to the development of products enriched with plant components. The purpose of this work was to study the effect of mixtures of powders of vegetable origin on the properties of dough and the quality of finished products (bakery trifles). Vegetable mixtures were added to the recipe of the products: No. 1 - sea buckthorn powder, honeysuckle, small-fruited apples and pumpkin cake powder; No. 2 - sea buckthorn powder and small-fruited apples, in the amount of 10, 15 and 20 % of the flour weight by dry matter. The mixtures were made up of components taken in equal quantities. A comparative assessment of the nutritional value of the mixtures showed that the amount of dietary fiber, calcium and phosphorus in mixture No. 1 is higher, relative to mixture No. 2. The mixture No. 2 is dominated by the amount of proteins, fats, organic acids, potassium, sodium, manganese and iron. In terms of vitamin content, the advantage is on the side of mixture No. 2, with the exception of vitamins B and B. An increase in the acidity of the dough was established, with the introduction of vegetable mixtures, which indicates an intensification of the fermentation process. The study of the quality of finished products showed that when the physico-chemical parameters meet the requirements of technical documentation, at dosages of mixtures above 10%, a significant darkening of the color of the products, the appearance of a vegetable taste, and in products with the addition of mixture No. 1, an unpleasant aftertaste was noted. The most rational recipe for the production of bakery products of increased nutritional value for a healthy diet is recognized, using a vegetable mixture No. 2 of sea buckthorn powders and small-fruited apples in an amount of 10 % by weight of flour.

The article reflects the assessment of the quality of sour cream at home, and considers methods for determining the quality of sour cream. Organoleptic evaluation was performed for compliance with the requirements of GOST 52092-2003 " Smetana. Technical conditions " in terms of appearance, consistency, color, taste and smell. The consistency of sour cream is determined during its mixing, while evaluating the presence of a glossy appearance of sour cream. Sour cream is considered thick if it slowly drains from the whorl. The smell is determined immediately after mixing. Then we evaluate the taste. When evaluating the quality of the samples under study, it was found that the organoleptic characteristics of the samples fully comply with the requirements of the regulatory document. Analyzing the results of the experiment, we can conclude that in the first experiment, the sour cream purchased on the market was completely dissolved, and the sour cream from the store after dissolution showed small grains. And in the second experiment, the results showed that the color did not change in the sample # 2, but under # 1 it turned blue. The basis of this experiment is a qualitative chemical reaction to starch, which is used as a thickener.

Within these contexts, the Paciência River, located on the Island of Maranhão stands out for its local importance, mainly for contributing its waters to the recharge of the underground springs, source of public supply of several districts of São Luís, capital of the state. However, this river has been compromising the quality of its waters, a consequence of the process of use and occupation of the spaces in its basin. Highlighting as one of the main problems related to the quality of fluvial environments, eutrophication, which consists of the process in which the body of water acquires high levels of nutrients (phosphates and nitrates), is a determinant indicator of water quality. In this sense, the objective of this work was to characterize the water quality and trophic status in the Paciência river basin through the physico-chemical parameters, showing the most compromised stretches according to the values reached in the analyzes. The results of the analyzes were compared with CONAMA No. 357/05 which indicated a worrying situation regarding the quality of the water at the place of study.Keywords: Water quality; Eutrophication; Island of Maranhão. RESUMENBrasil tiene gran disponibilidad de agua dulce en sus manantiales.

This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.

Abstract The aim of this study is to determine the effectiveness of disinfectant on the viability of eggs from three nematode species (Ascaris, Trichuris, Ankylostoma). It was conducted in a microcosm from June 2018 to June 2019. The wastewater scan was sampled using 5 L sterile containers, the sample was arranged in four replicas, three tests and one control. The test samples received three disinfectants (Moringa, calcium hypochlorite and Moringa associated with calcium hypochlorite) at varying concentrations. The physical and chemical parameters were measured before and after the application of each disinfectant. The samples were then observed under an optical microscope. The viability of the eggs was determined by incubating the Petri dish samples at 30 °C for 30 days. The analyses show that some physicochemical parameters can significantly influence the efficacy of disinfectant on the eggs. The calcium hypochlorite associated with Moringa at 0.6 g/L showed greater efficacy on reducing viability and inactivation of eggs with 100% efficacy yield rates on Ankylostoma and Trichuris trichiuria and 97% on Ascaris lumbricoides eggs; this efficacy is significantly different from that observed on samples treated with Moringa and simple calcium hypochlorite. Of the three parasites tested, A. lumbricoides showed greater resistance to the disinfectant.
