In this article, it is proposed to improve the technology of preparing baursaki dough for children with the addition of carrot flour. I focused on the advantages and features of carrot flour, was selected as an additive to the test for baursaks, and analyzed the chemical composition. In the course of the study, for wheat flour 5%, 10%, 15%, 20%, 25% cook baursaks with the addition of carrot flour. The dough was kneaded with a mixer, as it had a creamy consistency. Baked baursaks with the addition of carrot flour had good organoleptic quality indicators. The use of an optimal recipe prepared with the addition of carrot flour to wheat flour shows the effectiveness of the production of national baursaks and allows not only to improve the quality of finished products, but also to expand the range of food for children. Baursaks prepared from a mixture with 15% carrot flour are recognized as the most suitable for organoleptic and physico-chemical parameters.

The results of the influence of a dry powder obtained from Antonovka apples growing in the Kursk region on the consumer properties of crispbreads in which whole wheat and rye flour were partially replaced with apple powder in the amount of 10, 15 and 20% are presented. The optimal content of dried apple powder in baked samples of crispbread was determined during the experiment by the results of a study of organoleptic and physico-chemical quality indicators of samples. To assess the quality of the developed samples of crispbreads, an expert method was used to determine the weighting factors of product quality indicators. In the course of the calculations for experts, the most significant indicator was taste; the second by weight - appearance; the third is smell; fourth is form; fifth – color; the sixth is a view in kink. During the study of organoleptic indicators using a point scale, the largest amount of points (28.8 points) was gained by a sample of bread with the addition of 20% apple powder (it replaced 10% whole wheat and rye flour, respectively). This sample had an appearance interspersed with flavors and the presence of minor bubbles; pleasant taste and smell characteristic of apples; uniform color; rectangular shape; layered, with uniform porosity, without swelling, hardening, traces of an unbreakable appearance in a kink. The study of physical and chemical parameters made it possible to establish that with an increase in the amount of the additive (Antonovka apple powder), the mass fraction of moisture and acidity increase due to dietary fiber and acids that make up the apple powder.

The analysis of modern achievements in the technology of producing bread from triticalе flour using additives of vegetable origin has shown that the finished product is not always characterized by a balanced chemical composition caused by a low content of micronutrients, organoleptic indicators, uneven porosity of the crumb. Obtaining bread of increased nutritional and biological value is achieved due to the use of carrot powder and triticalе flour of the T-70 variety. The bread prepared accordingto the proposed method has improved physico-chemical parameters, which ensures the production of products of sufficient volume with a more elastic crumb and well developed porosity. To evaluate the quality of bread, generally accepted methods were used in the bakery industry. Protein content was determined by Kjeldahl titrimetric metod (GOST 13496.4–93), phosphorus was determined by vanado molybdate metod (GOST 26657–97), calcium content was determined by trilonometry metode with fluorexone (GOST 26570–95). Bread obtained using additives of plant origin is of interest from the point of view of chemical composition and can be considered as a product of therapeutic and prophylactic purpose.

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.

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.
