Abstract Most objectively, the dough rheological methods can characterize the quality of winter wheat. The Farinograph test is the traditionally used one in Hungary, but the importance of other methods, such as Alveograph and Extensograph tests, are getting more widely known due to the interest and requirements of the industry and export markets. The Hungarian Standard on wheat quality follows the changes in the global markets; this is why the falling number appeared in the MSZ (Hungarian Standard) 6383 in 1998. As the interest in the results of other rheological test increased from our accession to the European Union, the evaluation of these parameters on different varieties has become an important issue of qualification and in 2012 limit values for Alveograph and Extensograph parameters appear in the Hungarian wheat quality standard. Additionally, while the baking value was the only evaluated parameter of the Farinograph test earlier, the standard was supplemented with limit values for water absorption capacity and stability too. In this study, we revised different diagrams of Farinograph tests again from the previous years to reveal whether the new limit values for these Farinograph parameters change the valuation of wheat flour samples, therefore whether the quality groups in which the samples were ranked change considering the new requirements.

The European Parliament (EP) symbolizes many of the struggles that characterize the process of European integration and is at the core of many theoretical and empirical debates about representation, accountability, and legitimacy. This chapter draws on a variety of theoretical approaches to explain the complex role the EP plays in the political system of the European Union (EU). It starts with a brief overview of the history and functions of the assembly, followed by a theoretical explanation of its empowerment over time. Then, it determines the extent to which the EP is capable of influencing policymaking, both in legislative and non-legislative domains, as well as for the appointment of the Commission. It presents the political structure of the assembly and underlines the role of parliamentary groups and committees. It discusses the representativeness of the EP and the democratic quality of its internal functioning. Finally, it addresses current and future challenges for the EP.

Deoxynivalenol (DON) is the most commonly found mycotoxin in scabbed wheat. In order to reduce the DON concentration in scabbed wheat with superheated steam (SS) and explore the feasibility to use the processed wheat as crisp biscuit materials, wheat kernels were treated with SS to study the effects of SS processing on DON concentration and the quality of wheat. Furthermore, the wheat treated with SS were used to make crisp biscuits and the texture qualities of biscuits were measured. The results showed that DON in wheat kernels could be reduced by SS effectively. Besides, the reduction rate raised significantly with the increase of steam temperature and processing time and it was also affected significantly by steam velocity. The reduction rate in wheat kernels and wheat flour could reach 77.4% and 60.5% respectively. In addition, SS processing might lead to partial denaturation of protein and partial gelatinization of starch, thus affecting the rheological properties of dough and pasting properties of wheat flour. Furthermore, the qualities of crisp biscuits were improved at certain conditions of SS processing.

The effects of flour extraction rate and flour particle size (flour-sieve aperture) on the physical dough properties and cookie-making quality of soft wheat flour were examined during the development of a soft wheat experimental milling procedure. Soft wheats were milled to three extraction rates, and flour particle size was manipulated by changes in flour-sieve clothing. Physical dough properties, as measured by the farinograph and the alveograph, were weakly affected by milling procedure. However, cookie spread, cookie ratio and total cookie score exhibited strong negative relationships to both flour extraction rate and flour-sieve aperture. Soft wheats of different intrinsic cookie-making quality were ranked similarly by all milling procedures. Key words: Soft wheat, experimental milling, cookie-making quality, soft wheat quality screening

Проведена сравнительная оценка влияния добавки порошков из капусты брокколи (ПБ) на показатели качества пшеничной муки высшего сорта. В качестве объекта исследования были порошки, полученные конвективным и лиофильным способами сушки из капусты брокколи сорта Тонус (Россия) и гибрида Маратон F1 (Франция). Установлено, что ПБ сорта Тонус и ПБ гибрида Маратон F1, внесенные в муку, идентично влияют на показатели качества пшеничной муки и свойства теста: существенно не изменяют качества клейковины, приводят к повышению водопоглотительной способности муки, что обусловливает более равномерную консистенцию теста, увеличение объема и выхода готовых изделий в производственных условиях. При использовании ПБ гибрида Маратон F1 выявлено повышение показателя газообразующей способности пшеничной муки за счет наименьших размеров частиц добавки (0,14–0,15 мм), что позволяет рекомендовать этот порошок при производстве хлебобулочных изделий из пшеничной муки с пониженной газообразующей способностью. Порошки из капусты брокколи сорта Тонус и гибрида Маратон F1 способствуют повышению показателя вязкости водно-мучной суспензии в процессе клейстеризации крахмала, что обосновывает их использование в технологии хлебобулочных изделий из муки пониженного качества – с увеличенной активностью амилолитических ферментов. Таким образом, доказана возможность использования овощных порошков из отечественного сырья – капусты брокколи сорта Тонус в производстве хлебобулочных изделий, в частности для корректировки хлебопекарных свойств пшеничной муки. A comparative assessment of the effect of the addition of broccoli powders (PB) on the quality of wheat flour of the highest grade was carried out. The powders obtained with convective and freeze-drying methods of broccoli varieties Tonus (Russia) and hybrid Maraton F1 (France), had as object of study. It was found that PB varieties Tonus and PB hybrid Maraton F1, introduced into the flour, the same effect on the quality of wheat flour and the properties of the test: do not significantly change the quality of gluten, lead to an increase in water absorption capacity of flour, which causes a more uniform consistency of the dough, an increase in the volume and yield of finished products in production conditions. An increase in the gas-forming ability of wheat flour was revealed when using the PB hybrid Maraton F1 due to the smallest particle size additives (0,14–0,15 mm), which allows us to recommend this powder in the production of bakery products from wheat flour with reduced gas-forming ability. Powders of broccoli cabbage varieties Tonus and hybrid Maraton F1 contribute to increasing the viscosity of water-flour suspension in the process of gelatinization of starch, which justifies their use in the technology of bakery products from flour of reduced quality - with increased activity of amylolytic enzymes. Thus, the possibility of using vegetable powders from domestic raw materials – broccoli cabbage of Tonus variety in the production of bakery products, in particular for correction baking properties of wheat flour, is proved.

The role of clinical pathologists or laboratory-based physicians is being challenged on several fronts—exponential advances in technology, increasing patient autonomy exercised in the right to directly request tests and the use of non-medical specialists as substitutes. In response, clinical pathologists have focused their energies on the pre-analytical and postanalytical phases of Laboratory Medicine thus emphasising their essential role in individualised medical interpretation of complex laboratory results. Across the European Union, the role of medical doctors is enshrined in the Medical Act. This paper highlights the relevance of this act to patient welfare and the need to strengthen training programmes to prevent an erosion in the quality of Laboratory Medicine provided to patients and their physicians.

<p>The purpose of this research was to develop and evaluate a snack product (chin-chin) from composite maize-wheat flour blends enriched with edible palm weevil (<em>Rhyhnchophorus phoenicis</em>) paste. The maize-wheat chin-chin enriched with <em>R. phoenicis </em>were subjected to acceptability test using twenty member semi-trained panelist. The moisture, fat, protein and carbohydrate compositions of the snack samples had significant differences in their values. Sample 5M5R90W (containing 5% maize flour and <em>Rhyhnchophorus phoenicis </em>paste and 90% wheat flour) had the highest protein value of 19.05% while the least value 9.39% was obtained by sample 100M0R0W (100% maize flour alone). Sample 100M0R0W containing 100% maize flour also had the highest carbohydrate value of 75.24%. There was no significant difference in the ash and crude fiber contents of the chin-chin samples enriched with edible palm weevil paste. There were significant differences (P ≤ 0.05) in the functional properties of maize-wheat composite flour blends. Their wettability values ranged from 46.67 – 200 while the swelling index, bulk density and oil absorption capacity showed no significant difference in their values. The result of the mineral analysis showed phosphorus, magnesium and sodium had significant differences in their values in the range of 317.55 – 376.75mg/100g; 5.60 -13.60mg/100g;59.0 – 70.3mg/100g, respectively. There were no significant differences in the sensory attributes of the chin-chin samples. The result showed that an acceptable chin-chin product can be processed with the inclusion of the larva of edible palm weevil with maize-wheat composite flour to enhance the nutritional quality of the product.</p>

In recent years, there have been legislative cha nges as a result of which the role of the Pole’s Card in the Polish legal system has been increasing. The growing importance of the Pole’s Card requires refl ection on its place in the system of Polish law on foreigners and its relation to other institutions of this law. According to the original concept, the Pole’s Card was to be an offi cial confi rmation of the holder’s belonging to the Polish Nation and a way of granting a number of rights in order to make the foreigner’s stay in Poland easier. Today, it is justifi ed to say that the Pole’s Card has acquired a new, “stay-in” function. Although the Card on its own does not give the right to reside in Poland, it allows its holder to apply for a permanent residence permit without having to meet standard migration requirements. The changes have also made it legitimate to talk about a “repatriation” function of the Pole’s Card. It does not grant Polish citizenship, nevertheless it lets to avoid many diffi culties connected to standard procedures. As far as leaving the country is concerned, the Pole’s Card does not constitute an obstacle to the imposition on its holder of an obligation to leave Poland. However, it should be noted that while fulfi lling its functions, the Card signifi cantly reduces the likelihood of addressing a decision containing such an obligation. The attractiveness of the Pole’s Card holder status is demonstrated in practice by the growing interest in applying for this document. In the system of the law on foreigners, however, there remain some details that show that the whole concept is somehow incomplete. In practice, problems arise with the assessment of the connection to Polish culture and there are questions about the eff ects of unfair practices when applying for the Pole’s Card. Doubts are also raised by the lack of unifi cation of the Card holder status, irrespective of the possession of another privileged status: the one of a citizen of the European Union or a member of her or his family. It leads to a conclusion that legislative corrections seem necessary at some points. At the same time it is claimed that apart from the above, the quality of the application of the existing law should be improved.
