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.

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.

Abstract Water is a social requirement and an important factor in the ecological balance. Water from wells is good for direct consumption if the soil is not contaminated. The quality of drinking water is regulated by Law no. 458/2002 (transposing the Directive 98/83/EC on the quality of drinking water). The aim of this paper was to assess the physicochemical qualities of groundwaters from Brestea village, commune Denta, Timis County. The water samples were taken in 2015 from 10 functional wells. For the source whose physical and chemical parameters have exceeded the limit values, the monthly monitoring of the water quality (microbiological and physico-chemical properties) has been performed for 2 years. At the same time, the pH of the soil near the water sources was also measured. The results highlighted a good connection between the microorganisms from water and the nitrite, nitrate and ammonium content of water. The information can be further used to identify and eliminate the specific pollutants, areas and pollution sources.

The ongoing degradation of the water quality of central Maharashtra’s basaltic aquifer is of great concern for different authorities and agencies involved in the water sector in the Maharashtra, India. The Kham river, which is one of the major tributaries of the Godavari river, receives all domestic and industrial waste water from the Aurangabad city. The river, with no natural flow in the dry season, is extensively used for irrigation. In order to evaluate the quality of river and groundwater in the study area, eight river water and forty groundwater samples along right and left bank of the Kham river were collected and analyzed for various parameters. Physical and chemical parameters of the river and groundwater such as pH, TDS, EC, SO4, NO3 and heavy metals like Pb, Cr, Cd, Zn, and Cu were determined. The results show that the river and groundwater of the area is generally unfit for domestic uses. Most of the physico-chemical parameters and heavy metals in the river and groundwater samples have higher value than the World Health Organization (WHO, 2006) and Bureau of Indian Standards (BIS, 2003) guidelines.

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.
