Цель данной статьи - совершенствование методологии комплексной оценки хлебопекарных свойств продовольственной пшеницы и хлебопекарной муки. Учеными ВНИИ зерна предложена единая система комплексной оценки качества хлебопекарной пшеницы и муки, которая предполагает объединить все этапы производства и переработки пшеницы на единых принципах: наличие единого критерия оценки качества зерна и зернопродуктов, начиная с селекции и семеноводства, выращивания зерна и заканчивая мукомольным и хлебопекарным производством; единая система классификаций, основанная на единых показателях хлебопекарных свойств и взаимоувязанных норм по ним в классификациях на семена, товарное зерно, муку, хлеб; единые методы оценки хлебопекарных свойств зерна и зернопродуктов на различных этапах производства и переработки пшеницы; единый комплекс приборов и лабораторного оборудования для оценки качества зерна и муки, в том числе по показателям хлеба, на различных этапах производства и переработки пшеницы. В настоящее время с помощью компьютерной техники и современного программного обеспечения выявлен минимальный комплекс показателей, обеспечивающих объективную характеристику хлебопекарных свойств пшеницы, который включает «количество клейковины», «качество клейковины» и «число падения» при обязательном условии оценки их в комплексе. Эти показатели хорошо коррелируют с качеством хлеба, в частности с объемным выходом хлеба: чем выше количество клейковины, крепче качество клейковины, ниже число падения, тем больше объем хлеба. В этой связи для получения хлеба необходимого качества большое значение имеет установление верхнего значения для показателя «число падения», который по предложенным квалификационным нормам равен 340 с. The purpose of this article is to improve the methodology for a comprehensive assessment of the baking properties of food wheat and bread flour. Scientists from the All-Russian Grain Research Institute have proposed a unified system of comprehensive assessment of the quality of bakery wheat and flour, which involves combining all stages of wheat production and processing on the same principles: availability of a single criterion for assessing the quality of grain and grain products, starting with breeding and seed production, growing grain, and ending with flour and bakery production; a unified system of classifications based on uniform indicators of baking properties and interrelated norms for them in classifications for seeds, commercial grain, flour, bread; uniform methods for assessing the baking properties of grain and grain products at various stages of production and processing of wheat; a unified set of instruments and laboratory equipment for assessing the quality of grain and flour, including the indicators of bread at various stages of production and processing of wheat. At present, with the help of computer technology and modern software, a minimum set of indicators has been identified that provide an objective characterization of the baking properties of wheat, which includes the «amount of gluten», «quality of gluten» and «falling number» with the obligatory condition of their assessment in the complex. These indicators correlate well with the quality of bread, in particular, with the volumetric yield of bread: the higher the amount of gluten, the stronger the quality of the gluten, the lower the falling number, the larger the volume of bread. In this regard, in order to obtain bread of the required quality, it is of great importance to establish the upper value for the «falling number» indicator, which, according to the proposed qualification standards, is 340 с.

Two sprout-damaged wheat lots with the falling number values of 91 and 65 were heat-treated by immersing the grain in water of temperatures of 80, 85, 90 and 100°C, followed by rapid chilling in water. The purpose of the treatment was to suppress the excess a-amylase activity in the outer layers of the kernels. The a-amylase activity following the treatment was measured by the falling number test. The increase in the falling number value was the greater the longer the treatment lasted and the higher the water temperature was. Processing lasting 30 sec at 80, 85, 90 and 100°C increased the falling number value of the one lot from 91 to 105, 117, 133 and 238 and of the other lot from 65 to 69, 70, 98, 163, respectively. As the falling numbers increased the wet gluten content of the samples decreased. These changes had a negative correlation. The gluten quality showed heat damage when the amount of gluten had dropped by about 5 and 2 precentage units in the lots with the falling numbers 91 and 65, respectively. This occurred at processing of the lot of better quality for 70, 20, 13 and 6 sec in the order of increasing temperature. The corresponding durations for the other lot were above 60, 30, 20 and 6 sec. During these treatments the falling number values rose from 91 to 104—129 and from 65 to 70—71. These results were confirmed by farinogram and extensigram determinations and by baking tests. The same processing conditions affected more severely the lot having the better initial quality than the lot with greater sprout damages.

The bread-making quality of forty commercial winter wheat samples, grown in the western region of the CzechRepublic, and their flours (white flours with ash content of about 0.5%) prepared in a commercial mill was studied. Standard analytical methods (ash and protein content, wet gluten), amylolytic activity measurement (falling number), rheological investigation (alveograph, gluten index), sedimentation test and laboratory baking test were used for characterization of wheats and flours. In addition NIR method was used to calculate ash, wet gluten, sedimentation value and protein content. Statistically significant correlations were found practically between all tested quality parameters of wheat and corresponding flour samples. However, the strongest correlation (r = 0.69–0.70) significant at 0.01 level exists between specific bread volume and protein and wet gluten content, determined both by standard or by NIR methods.

Abstract Due to the constantly growing demand for flour confectionery and culinary products, it became necessary to develop specialized requirements for the quality of wheat flour as a raw material. To date, there are no such requirements in our country, and for the production of these products, bakery flour obtained according to the traditional wheat grind scheme was used, the quality of which had to be leveled depending on the range of confectionery products. One way to solve this problem is to differentiate the properties of wheat flour according to its intended purpose and their rationing. The purpose of the study is to develop quality requirements for Russian wheat flour for the production of wafer sheets according to objectively and reliably determined indicators of the dough rheological properties using an alveograph device to create, in the future, a system for classifying wheat flour by its intended purpose. Flour quality assessment was carried out using domestic devices and laboratory equipment (MOK system, Falling-number value, etc.); the dough rheological properties were evaluated by an alveograph device (company Chopin, France), wafer sheets were baked and evaluated using methods previously developed by the authors. The analysis of the interdependence of standardized quality indicators, as well as newly developed ones, was conducted to identify indicators that differentiate the quality of wheat flour by its intended purpose, i.e. by finished products. For this, methods of mathematical statistics were applied.

At present the laundry business is one of the promising businesses with targeted consumers from the upper middle class who do not have much time to wash clothes at home. Like other industries, laundry also produces wastewater that can have a negative impact on the environment if it is not managed properly. This study characterizes laundry wastewater and looks at its effect on the quality to the groundwater/wells close to the laundry business. Water samples include TSS, TDS, Turbidity, pH , COD, BOD, Phosphate, and Detergent parameters analyzed according to SNI and/or the HACH method (DR3900). Characterization of the laundry wastewater samples show a high level of detergent and phosphate parameters ranging from 27,7-39,4 mg/L and 6,1-27,1 mg/L, respectively with the highest levels corresponds to Laundry wastewater samples at Jalan Baru. The detergent and phosphate contents in all well water samples are still below the required quality standard. Although the concentrations of parameters analysed in the laundry wastewater  are very high and above the guidance, it is obvious from the well water samples results that there is no effect of laundry waste waters to the quality of ground waters.

Liquid effluents discharged by hospitals may contain chemical and biological contaminants whose main source is the different substances used for the treatment of patients. This type of rejection can present a sanitary potentially dangerous risk for human health and can provoke a strong degradation of diverse environmental compartments mainly water and soils. The present study focuses on the quality of the liquid effluents of Hassani Abdelkader’s hospital of Sidi Bel-Abbes (West of Algeria). The results reveal a significant chemical pollution (COD: 879 mgO2/L, BOD5: 850 mgO2/L, NH4+ : 47.9 mg/l, NO2- : 4.2 mg/l, NO3- : 56.8 mg/l with respect to WHO standard of 90 mgO2/L, 30 mgO2/L, 0.5 mg/l, 1 mg/l and 1 mg/l respectively). However, these effluents are biodegradable since the ratio COD/BOD5 do not exceeded the value of 2 in almost all samples. The presence of pathogen germs is put into evidence such as pseudomonas, the clostridium, the staphylococcus, the fecal coliforms and fecal streptococcus. These results show that the direct discharge of these effluents constitutes a major threat to human health and the environment.
