Приведены экспериментальные данные по применению полисахаридов в рецептуре и технологии хлеба из композитной смеси пшеничной и гречневой муки с соотношением 85 : 15. Изготовлены образцы хлеба из композитной смеси муки с полисахаридами в концентрации 0,5; 0,6; 1,0 и 1,5%. Установлено, что добавление ксантана в концентрации 0,5% улучшает органолептические и физико-химические показатели готового изделия. Определено, что влажность и пористость хлеба повысились на 1,57 и 15% соответственно, кислотность уменьшилась на 0,3 град. по сравнению с контролем – хлебом из пшеничной муки (ГОСТ Р 56631–2015). Отмечено увеличение содержания витаминов и минеральных веществ в опытном образце, %: тиамина на 100; рибофлавина – 150; калия – 1,3; кальция – 23,7; магния – 42,4; фосфора – 38,6; железа – 50. Содержание белков, жиров и углеводов в образце хлеба с ксантаном увеличилось незначительно, на 5,2; 12,5 и 10,3% соответственно, что обусловило повышение энергетической ценности на 7,2%, содержания пищевых волокон на 7,7% по сравнению с контролем. Определено, что применение ксантана позволяет пролонгировать срок хранения хлеба из композитной смеси пшеничной и гречневой муки на 24 ч. Experimental data on the use of polysaccharides in the formulation and technology of bread made from a composite mixture of wheat and buckwheat flour with a ratio of 85 : 15 are presented. Bread samples were made from a composite mixture of flour with polysaccharides at a concentration of 0,5; 0,6; 1,0 and 1,5%. It was found that the addition of xanthan at a concentration of 0,5% improves the organoleptic and physico-chemical parameters of the finished product. It was determined that the humidity and porosity of bread increased by 1,57 and 15%, respectively, and the acidity decreased by 0,3 degrees compared with the control –bread made from wheat flour (GOST R 56631–2015). There was an increase in the content of vitamins and minerals in the experimental sample: thiamine by 100%; riboflavin – 150%; potassium – 1,3%; calcium – 23,7%; magnesium – 42,4%; phosphorus – 38,6%; iron – 50%. The content of proteins, fats and carbohydrates in the sample of bread with xanthan increased slightly, by 5,2; 12,5 and 10,3%, respectively, which led to an increase in energy value by 7,2%; the content of dietary fiber increased by 7,7% compared to the control. It is determined that the use of xanthan allows you to extend the shelf life of bread from a composite mixture of wheat and buckwheat flour for 24 hours.

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.

Background: Lippia multiflora Moldenk is a shrub that is present in Benin. It is used as nutritious food and its leaves and flowers are rich in mineral salts and especially vitamin A and C. Also, these leaves and flowers transformed into powders, are sold and used to flavor sauces and for other purposes. Aim/Objectives: Our work aims to provide consumers with information on the sanitary and hygienic quality of the powders from the leaves and flowers of Lippia multiflora in order to determine their shelf life. Methods: The study was carried out on three different powders, namely leaf-based powder; those from the flowers and those purchased from the sellers. Physico-chemical analyses and microbiological evaluation were made on these different powders at different dates for 18 months to see the growth of the microorganisms in these powders. Results: These analyses revealed that the means of the physico-chemical parameters in the leaf-based powders, the flowers and those sampled are respectively: water content (7.42%; 9.89% and 11.67%); ash content (15.83%; 10.77% and 6.52%); pH (7.25; 6.22 and 5.95) and titrable acidity (0.55%; 2.46% and 1.84%). Microbial loads in total flora are below the standard for 18 months in leaf and flower powders but are above the standard in powders sampled after 12 months of storage. The growth of yeasts and molds was observed during the first 6 months and their load is well below the standards from the 7th month until the end of storage. Coliform, Salmonella, Staphylococcus aureus, faecal Streptococci and Clostridium sulfito-reducers loads are below the detection threshold throughout the shelf life. Conclusion: Therefore the powders based on the leaves and flowers can be kept for a period of eighteen months without risk to the consumer. But those sampled can be kept for up to 12 months.

O Brasil apresenta grande disponibilidade de água doce em seus mananciais. Fazendo parte desse recurso encontra-se, o rio Paciência, localizado na Ilha do Maranhão destacado pela sua importância local, principalmente por contribuir com suas águas para recarga dos mananciais subterrâneos, fonte de abastecimento público de vários bairros de São Luís, capital do estado. No entanto, este rio vem sofrendo comprometimento da qualidade de suas águas, consequência do processo de uso e ocupação dos espaços em sua bacia. Destacando-se como um dos principais problemas relacionados a qualidade de ambientes fluviais,  a eutrofização, que consiste no processo em que o corpo d’água adquire elevados níveis de nutrientes (fosfatos e nitratos), é um indicador determinante da qualidade da água. Neste sentido, o objetivo deste trabalho foi caracterizar a qualidade da água e do estado trófico na bacia hidrográfica do rio Paciência atráves dos parâmetros fisico-químico evidenciando os trechos mais comprometidos conforme os valores alcançados nas análises. Os resultados das análises foram comparados com a CONAMA No. 357/05 que indicaram uma situação preocupante quanto à qualidade da água no local de estudo.Palavras-chave: Qualidade de água; Eutrofização; Ilha do Maranhão. ABSTRACTThe Brazil has great availability of fresh water in its springs. 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.

The antioxidant activity of cookies prepared by the addition of sugarbeet dietary fibers was investigated in order to estimate their influence on functional characteristics and shelf-life of cookies. Treated fiber (TF) was obtained from sugarbeet by extraction with sulfurous acid (75 °C at pH = 5.7during 60 min) and treatment with hydrogen peroxide (20 g/LH2O2 at pH = 11 during 24 h). The fiber obtained was dried (80 °C), ground and sieved. TF was investigated in comparison with commercially available Fibrex®. The cookies were prepared by the addition of 0, 7, 9 and 11% of sugarbeet dietary fiber as a substitute for wheat flour in the formulation of cookies. The antioxidant properties of cookies were tested every 7 days using a DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity test during 6 weeks of storage at room temperature (23 ± 1 ºC). The obtained results indicated that substitution of wheat flour with Fibrex® in the formulation of cookies upgraded the antioxidant activity, i.e. the functional characteristics of Fibrex®-enriched cookies and could prolong their shelf-life. In contrast, TF did not increase the antioxidant activity of TF-enriched cookies. The better antioxidant activities of Fibrex®-enriched cookies could be attributed to the presence of ferulic acid.

Sugar beet pulp (SBP) is a by-product of the sugar industry in which the dietary fiber content ranges from 73% to 80%. Compared to cereal fibers mainly used in biscuit production, sugar beet fibers are gluten free and have a perfect ratio of 2/3 insoluble fiber. In this work, sugar beet pulp was extruded with corn grits (ratios of corn grits to sugar beet pulp in extrudates were 85:15, 70:30, and 55:45), and the obtained sugar beet pulp extrudates (SBPEs) were used for improving the nutritional quality of cookies. The wheat flour in cookies was replaced with SBPEs in the amount of 5, 10, and 15%. The influence of three factors (the percentage of sugar beet pulp in the SBPEs, the size of the SBPE particles, and the percentage of wheat flour substituted with SBPEs) and their interactions on the nutritional quality of cookies, as well as their physical and sensory characteristics are examined using the Box–Behnken experimental design. The addition of extruded sugar beet pulp (SBPEs) significantly increased the amount of total dietary fiber and mineral matter of cookies. On the whole, the addition of SBPEs increased cookie hardness, but the hardness decreased with an increase in extrudate particle size. Sensory characteristics (except for the taste) were the most influenced by extrudate particle size.

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.

Effects of different levels of wheat flour as dietary fiber on the quality of fresh and preserved beef meatballs during storage were explored in this study. Ground beef (Batter) samples were divided into four treatment groups and treated with different level of wheat flour as T1 (control, 0%), T2 (5%), T3 (10%) and T4 (15%). Proximate analysis (dry matter, ash, ether extract and crude fat), sensory tests (color, flavor, tenderness, juiciness, overall acceptability), biochemical analysis (free fatty acids, Thiobarbutiric acid values and peroxide value) and microbiological examination were carried out as responses at the interval of 0, 30 and 60 days during storage at -200C. The experimental design was a 4 × 3 factorial in Completely Randomized Design replicated three times per cell. DM content was increased significantly (p<0.05) with the advancement of storage intervals. CP and EE content of all the treatments were decreased significantly (p<0.05) among the different treatment groups. FFA and TBARs values were differed significantly (p<0.05) at different treatment levels. PVs were decreased significantly (p<0.05) at different treatment levels. Color, cooking loss and overall acceptability were differed significantly (p<0.05) at different treatment levels. Raw and cooked pH were increased significantly (p<0.05) at different treatment levels. The juiciness at different treatment levels were decreased significantly(p<0.05).TVC (logCFU/g), TCC (logCFU/g) and TYMC (logCFU/g) were differed significantly (p<0.05) at different treatment levels. In conclusions, meatballs having 5% wheat flour was better in terms of color, odor, tenderness, juiciness and overall acceptability, cooking loss and microbial qualities.Bang. J. Anim.
