<p>Atrelado ao valor nutricional vem sendo atribuída à berinjela algumas propriedades funcionais, como a capacidade de diminuir o colesterol plasmático e o efeito hipoglicêmico. Por suas características nutricionais, a farinha de berinjela se destaca como um importante ingrediente alimentar, visto que apresenta, em relação à farinha de trigo, maior teor de proteínas, cinzas e fibra alimentar. Dados sobre os efeitos benéficos da berinjela evidenciam a importância do conhecimento detalhado de sua composição química para especificações nutricionais, adequação de dietas e para a ciência de alimentos. Em vista do manejo diferenciado, o cultivo sustentável demanda cultivares bem adaptadas e que proporcionem o melhor rendimento e elevado padrão de qualidade, o que pode interferir na composição dos frutos e, por conseguinte na farinha elaborada a partir destes. Dessa maneira, objetivou-se avaliar as características físico-químicas das farinhas de berinjela de diferentes genótipos sob o sistema de cultivo orgânico. Os resultados demonstraram que o genótipo comprida foi o que proporcionou a obtenção de uma farinha com maior potencial nutritivo, destacando-se nos conteúdos de proteínas, lipídeos e cinzas, frente aos demais materiais analisados.</p><p align="center"><strong><em>Physicalchemical quality of the flour of eggplants genotypes (</em></strong><em>Solanum melongena<strong> L.) submitted to an organic cultivation</strong></em></p><p><strong>Abstract</strong><strong>: </strong>Besides its nutritional value, it has been atributed to  eggplant some functional properties, just like the capacity to diminish  plasmatic cholestherol and its hypoglycemic effects, the eggplant outstands, for its nutritional characteristics, as an important ingredient , said that it shows in relation to wheat flour (ordinary baking flour) a bigger fiber and protein rate.

Abstract:The objective of this work was to evaluate the effects of prohexadione calcium concentrations on the growth and quality of eggplant (Solanum melongena) seedlings. The effects of prohexadione calcium concentrations of 0, 50, 100, or 150 mg L-1 on seedling growth parameters were evaluated in a greenhouse experiment. After the greenhouse experiment, the seedlings were transplanted to the field. During the field experiment, the number of days to flowering, plant height, number of fruits per plant, average fruit weight and yield were evaluated. Both experiments were carried out in a completely randomized design with four replicates. All prohexadione calcium concentrations significantly reduced shoot height and internode length, when compared to the control. The concentrations of 50, 100, and 150 mg L-1 prohexadione calcium reduced shoot height by 27, 32, and 38%, respectively. Prohexadione calcium treatments (except the one with 50 mg L-1) enhanced relative chlorophyll content of leaves in comparison to the control. There were no delays in flowering and no significant differences in number of fruits per plant among treatments with prohexadione calcium. The concentrations of 100 and 150 mg L-1 prohexadione calcium significantly reduced yield per plant and total fruit yield, whereas the concentration of 50 mg L-1 did not cause any change in yield compared to the control. The lowest prohexadione calcium concentration can be used to control excessive elongation of eggplant seedlings without yield loss.

Abstract. During the period 2017-2018, the feed quality and productivity of three Sudan grass varieties – Endje 1, Vercors and Super Sweet, one stabilized Sudan grass population – SWT, local sweet sorghum – „Zaharna metla“ population and the sweet sorghum cultivar “Shumensko sladko” were researched in Agricultural Institute – Shumen. Green mass (t/ha), dry matter (%) and dry mass production (%) as well as basic nutritional characteristics by the two swaths of the tested cultivars in brooming phase were controlled. It was found that the sweet sorghum cultivar “Shumensko sladko” gave the highest amount of green mass – 59.5 t/ha by two swaths, and the dry mass yield was the highest from the cultivar Endje 1 – 20.8 t/ha. In terms of chemical composition, the greatest variation was demonstrated in phosphorus content (0.369-0.696%, CV=27.3%), followed by crude fat (1.28-2.39%, CV=26.8%), Ca (0.889-1.572%, CV=21.8%), crude protein (6.05-9.00%, CV=14.6%), nitrogen free extracts (42.05-51.20%, CV=7.6%), crude fiber (32.64-39.26%, CV=6.1%) and mineral substances (8.17-9.61%, CV=5.9%). It can be summarized that all hybrids provide quality hay, however the Bulgarian cultivars Endje 1 and “Shumensko sladko” showed the best nutritional value – compared to Super Sweet, Vercors, SWT and “Zaharna metla”.

The Artemia is one of the most important live food in larviculture. Nevertheless the nutritional value is strongly variable and depends on strain and culture conditions. Nutritional characteristics of cyst from saltworks in Cuba were compared with ones from the Nippai Company usually used in larviculture centres. Proportions of total protein, lipids, ashes and fatty acids were determined to decapsulated cyst and fresh hatched nauplii. The highest protein content was found in cyst while total lipids and ashes shown the highest content in nauplii. The Artemia cyst from Cuban saltworks have a higher content of eicosapentaenoic acid (EPA) than the one from Nippai Company and can be classified as marine type.

Subject. The study addresses the improvement of risk management efficiency and the quality of lending decisions made by banks. Objectives. The aim is to present the bank management with a fair algorithm for risk management motivation on the one hand, and the credit management (business) on the other hand. Within the framework of the common goal to maximize risk-adjusted income from loans, this algorithm will provide guidelines for ‘risk management’ and ‘business’ functions on how to improve individual and overall efficiency. Methods. The study employs the discriminant analysis, type I and II errors, Lorentz curve modeling, statistical analysis, economic modeling. Results. The paper offers a mechanism for assessing the quality of risk management decisions as opposed to (or in support of) decisions of the lending business when approving transactions. The mechanism rests on the approach of stating type I and II errors and the corresponding classical metric of the Gini coefficient. On the ‘business’ side, the mechanism monitors the improvement or deterioration of the indicator of changes in losses in comparison with the market average. Conclusions. The study substantiates the stimulating ‘rules of the game’ between the ‘business’ and ‘risk management’ to improve the efficiency of the entire business, to optimize interactions within the framework of internal competition. It presents mathematical tools to calculate corresponding indicators of the efficiency of internally competing entities.

Podkarpackie Voivodeship is one of the regions of Poland in which the number of agritourism entities is very high. Therefore tourism plays a significant role in its development strategy. The aim of the paper is to identify the current state of agritourism and the changes that have occurred in the region in the years 2000–2016. Specific objectives are to determine the distribution of agritourism farms and their offer, together with a comprehensive analysis of the environmental and socio-economic factors, as well as the impact of the Slovak-Ukrainian border. The report was developed on the statistical materials from the Polish Central Statistical Office, Podkarpackie Agricultural Advisory Centre in Boguchwała and data collected from municipalities and district offices that is published on their websites, as well as through interviews with 100 owners of agritourism farms in the Podkarpackie Voivodeship. The research has shown, on the one hand, the decline in the number of farms in the region and, on the other hand, the increase in the diversity of the tourist offer of these entities. Distribution of agritourism farms is closely linked to the attractiveness of natural environment and quality of secondary tourism resources. Traditional agritourism has not yet fully used its countryside, as well as cross-border advantages of its location.

Background: Phytonutrients in peach fruits have health promoting antioxidants against various chronic diseases. However, there is no extensive data to show the nutritional values of Local peach cultivars after post-harvest treatments. Objective: Mainly this study was objective to determine the effect of calcium carbide on nutritional value and quality of fruits of Pakistani peach cultivars. Methods: The peach fruits were collected from three different peach orchids of KPK and the fruits were divided into 4 groups while 5th group was collected from local fruit shop. Each experimental group was treated with different concentration of calcium carbide whereas control group was not treated. The peel and pulp samples were oven dried and ground to fine powder separately. The elemental compositions were determined using Particle Induced X-ray emission and Pelletron Tandem Accelerator. Result: Sixteen elements were identified in peach fruits and the elements were Al, P, S, Cl, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, and Se. In peel, concentration of some elements increased or decreased after treatment with CaC2 while in pulp the conc. of nearly all detected elements was increased in treated samples. We found significantly high amount of heavy metals traces including As, Se, Co, Si, and P in peach fruits treated with CaC2. Interestingly, the presence of trichomes in peach skin prevents the transfer of these heavy metals deep into the pulp which was also verified by the elemental profiling of nectarines. Conclusion: Conclusively, the artificial ripening with CaC2 changed the nutritional value of peach fruits that has higher health risks if consume with the peel. According to our best knowledge, this is the first report that highlights the effects of CaC2 which deteriorate the nutritional value of peach fruits in Pakistan.

Type 2 diabetes has become one of the major health problems of the modern world. It is assumed that environmental factors have a significant impact on the development of the disease, and great importance is ascribed to the diet, which can be modified accordingly. The diet can exert prophylactic and therapeutic effects; changes in the diet in advanced disease can improve the quality of life of diabetic patients and minimise the risk of complications, which are the direct cause of diabetes-related death. Functional food, which has a potentially health-enhancing effect in addition to its nutritional value, has been increasingly recognised and required. Cereal products are crucial in diabetic nutrition. Their function can additionally be enhanced by fortification with compounds with proven hypoglycaemic effects. Pasta has a low glycaemic index and is a good carrier of fortifying substances; hence, it can be highly recommended in diets for diabetic patients.
