Megjegyzések:A 2000. évben két nagy árhullám vonult le a Tiszán, amelyek során nemcsak a cianidszennyezés okozott hatalmas károkat, hanem a nehézfémeket szuszpenzióként szállító ár is riadalmat váltott ki. Hatásaik vizsgálatára több kutatási program is indult, egyrészt az akkori Környezetvédelmi Minisztérium, másrészt az NSF?MTA?OTKA nemzetközi pályázati program keretében. Ez utóbbinak volt a koordinátora az Egyesült Államokból Domy Adriano és hazánkból Németh Tamás. Az ártérben lerakódott új talajréteg adta az ötletet, hogy vizsgáljuk meg az ártéri talajok elemtartal- mát, különös tekintettel a toxikus és potenciálisan toxikus elemekre. Ez négy helyen, a 276-709. folyamkilométer között történt mintavételek (talaj 0?300 cm) mintáinak elemzésével valósult meg. Több kivonószert alkalmazva foglaltuk össze az eredményeket az ólom és a kadmium elemekre. Az árterekben az új feltalaj elemekben gazdagabb lett, mint az alsó rétegek, de az elemek döntő hányada a nehezen oldható kémiai formákhoz tartozott. A legelők növénymintái egyik helyen sem mutattak akkumulációt a vizsgált elemekre.

Cím:Cultivating Crops as Alternative Protein Sources: Exploring Three Diverse Cereal Grain Varieties / Maha Khalfalla, László Zsombik, Zoltán Győri
Dátum:2024
ISSN:0239-1260
Megjegyzések:Protein-based plants, a key trend in food system transformation, hold immense potential to foster a sustainable and nutritious food system cycle. This research, which compares three ancient cereal grain varieties, aims to address pressing issues of environmental degradation, food security, and public health. The findings from these alternative protein sources promise nutritional benefits and offer diversity cultivation advantages, inspiring a promising future for our food systems and public health.The study stands out for its meticulous examination of cereal grain varieties, including proso millet (Gyöngyszem, Biserka, and Rumenka), winter wheat (SE15), and buckwheat (Hajnalka). These distinct varieties, registered with the Institute ofResearch and Study Farm, University of Debrecen, Nyíregyháza, were subjected to diverse cropping systems under the control of N fertilizer, particularly (N 27 % CAN), with a rate of (80 kg N/ha -300 kg/ha CAN), applied for each cereal grain for the 2021 and 2022 cultivation seasons. The statistical results, which showed a significant variance attributed to a variety group(P </- 0.05), confirm confidence in the reliability of the findings.Accordingly, the results revealed that the crude protein contents fluctuated among the tested varieties. They were 16.7 g/kg to 19.0 g/kg for proso millet varieties, 19.3 g/kg for winter wheat, and 17.4 g/kg for buckwheat. However, the extra crude protein in the buckwheat crop was linked to the adverse effect of the amount of N fertilizer used. This was evident as the control sample measured 18.4 g/kg and then dropped to 16.5 g/kg, indicating a negative correlation between N fertilizer and protein content. The findings also indicated that Hungarian proso millet varieties have abundant protein contents, which was a reason to examine the colour profile and sort the three respective varieties based on the varied colour profiles, which can contribute to predicting the physical properties that can affect of developed final product.Overall, protein-based plants are strategies that could contribute to the green revolution, SDGs targeting, quarantine of natural food sources, and protection against uncommunicable diseases, moreover, supporting that the finding outcomes could benefit the breeders, nutritionists, and industrial sector in a wide manner

Cím:Advancement of Sorghum Bicolor and Proso Millet as sustainable food products for human consumption / Maha Khalfalla, László Zsombik, Zoltan Győri
Dátum:2024
Megjegyzések:Sorghum bicolor and Proso Millet, commonly known as prominent crops supporting the Sustainable Development Goals (SDGs), provide a wide range of sustainable food production targets. Their growing acknowledgement in recent times, primarily attributed to their nutritional advantages and exceptional capability to withstand unfavourable weather, inspires optimization. The recent analysis delves into their nutritional composition, farming techniques, environmental sustainability, and socioeconomic ramifications. It also explores ongoing research and future possibilities, aiming to optimize these crops as primary food sources and develop and optimize them to address global food security issues. The investigation was performed at the Institute of Study Farm, Nyíregyháza, University of Debrecen. Sandy soil characteristics distinguished the production location. The study aimed to evaluate the total protein and the associated minerals that operate as co-factors in conjunction with total protein, including Mg, Fe, Zn, Cu, Mn, and S. The purpose of the study investigation was to assess the nutritional value of the selected grain varieties and their implications on human health across the food cycle. Therefore, we evaluated the fluctuation in nutritional content between the whole grains treated using a hammer mill and processed grains utilizing a unique husking procedure known as the Husking Fraction Time Unit (HFTU). The validity of our hypothesis was confirmed with a significance value of P < 0.05, indicating that the differences in nutrient concentrations between the two processing processes are statistically significant. The findings indicated that the husking procedure significantly impacted nutritional concentrations and redistribution in the cereal grains. This can be supported by the consistent variations observed, notably in tested nutrient levels, when were observed by the Rumenka variety (Proso millet) has the greatest average levels of total protein (N), iron (Fe), zinc (Zn), copper (Cu), and magnesium (Mg) at 18.5 g/kg, 107.9 mg/kg, 39.0 mg/kg, 8.8 mg/kg, and 2390.9 mg/kg, respectively, compared to other sorghum and proso millet varieties. The research offers valuable insights into the vital nutritional compositions that influence human diets and promote a healthy daily dietary routine via various product choices, including whole grains or processed grains derived from distinct, sustainable sources. The study's results have important consequences for the overall stability of the world's food supply. They indicate that growing and consuming sorghum and proso millet facilitates the establishment of a food system that is both environmentally friendly and provides essential nutrients.

Cím:Assessing Crude Protein Levels and Microelement Concentrations of Flour Grain Yield of Sorghum bicolor (L .) Moench Cultivars / Maha Khalfalla, László Zsombik, Zoltan Győri
Dátum:2024
ISSN:2585-8246
Megjegyzések:Sorghum bicolor (L.) Moench is scientifically known as a highly adaptable cereal crop with a high nutritional value, including significant amounts of crude protein and trace components. Crude protein encompasses various amino acids essential for growth, development, and maintaining quality. Trace elements play a crucial role in metabolism and activating enzymes. By examining the levels of crude protein and trace elements in various Hungarian sorghum cultivars, the research aims to show how nitrogen?s impact varies across different cultivars. The assessment research focused on six chosen cultivars: Zádor, Alföldi 1, ES Albanus, Albita, and Farmsugro180. These types displayed different hues, including red, red/brown, and white. The cultivar ES Föehn, developed by Lidea Seeds, served as the benchmark for European standards. The elements N, Fe, Zn, Cu, and Sr were selected for the intended investigation. The treatment consisted of a control group that did not get any nitrogen fertilizer and a treated group that received nitrogen fertilizer in the form of ammonium nitrate (Péti-só, 27% N). The treated group was managed with a 60 kg·ha-1 dosage in the experimental field. The findings revealed variations in the concentrations of elements depending on the different kinds within each category. Most of the analyzed groups exhibited a statistically significant p-value of less than 0.05, as determined by the variance of non-parametric data for Fe, Cu, Zn, and Sr. For example, Zádor exhibited abundant microelement contents, such as N (15.3 mg·kg-1), Fe (46.2 mg·kg-1), Cu (3.5 mg·kg-1), and Zn (23 mg·kg-1). Strontium (Sr) mineral showed a strong correlation, with a correlation copper of r = 0.66. The variety of mineral and protein levels seen in the examined cultivars is highly recommended as a valuable source of nutritious plant-based dietary resources, especially for developing concentrated protein sources. According to the findings, brown and red grain pericarp varieties have been identified as lucrative raw materials for investments in the industrial sector, mostly because of their high crude protein qualities.

Cím:Implications of husking process on the nutritional composition of sorghum grains: diverse varieties and regions / Maha Khalfalla, László Zsombik, Gerda Diósi, Zoltán Győri
Dátum:2024
ISSN:0950-5423
Megjegyzések:Sorghum, known for its nutritional value, health benefits and gluten-free status, is now widely produced and suitable for human consumption in developed regions due to advancements in sorghum research and processing techniques. The research looked at how well the husking fraction time unit (HFTU) technique worked by examining its effects on the nutritional value of three varieties of sorghum grain. The efficiency of the husking process was assessed at 87% for concentrated and redistributed nutritional contents and 60% for variation of mineral contents based on bran/ endosperm. The technique reduced the T.K.W. compared to whole grain to the endosperm (grits). Moreover, the redistribution of the crude protein % showed the precision of the HFTU procedure by demonstrating an average of 26.6% as a variation ratio of the bran/endosperm in the data set. Contrary to the content of the total dietary fibre content, for example, the variation of TDF % attributed to bran/endosperm was 10.9%. On the other hand, the aver- age ash % of whole grains (hummer) and husked products (TM05C) was increased by 33.2% based on averages of 1.5% and 2.1%, respectively. Accordingly, it was approved that the HFTU procedure effec- tively separated the endosperm (grits) and bran. This study also found that minerals such as Ca, Cu, Fe, K, Mg, Mn, Na, P, S and Zn changed over 30-to-80-time units by 29%, 13%, 8%, 4%, 17%, 18%, 1%, 13%, 6% and 12% in the bran and endosperm. The HFTU process has influenced the colour attributes of variation sorghum varieties, particularly within a time scale of 80 (S) units. The research revealed that the husking technique substantially impacted the different sorghum grain varieties' nutritional composi- tion and colour properties. The method can be useful for developers in enhancing sorghum grain prod- ucts' nutritional properties attributed to various varieties and regions, allowing them to provide high nutritional quality sourced from sustainable product

Cím:Promoting the elemental profile of sorghum grain: Driving factors affecting nutritional properties under nitrogen fertilizer conditions / Maha Khalfalla, László Zsombik, Róbert Nagy, Zoltán Győri
Dátum:2024
ISSN:2405-8440
Megjegyzések:Monitoring nitrogen utilization is crucial in agricultural practices, emphasizing the interrelationship between soil health, nutrient management, and human health. The study was conducted to evaluate the impact of N fertilizer on the nutritional characteristics of diverse S. bicolor varieties, namely Alfoldi ? 1, ES Foehn ? (Lidea Seeds) with a red pericarp, ES Albanus, Albita, and Farmsugro 180 (all white varieties), the study was conducted in sorghumproducing areas where the crop is non-native. Specifically, the study investigated two soil types: loam clay and sandy soil. Furthermore, the respective varieties were grown under N (27% N CAN) fertilizer conditions, involving 60 kg/ha? 1 and 120 kg/ha? 1 of the treatment rates applied at each experiment site. We measured the specific element concentration in each sample using the Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) technology. Certainly, the results demonstrated that the different S. bicolor varieties had unique nutritional characteristics attributed to several factors such as soil type, variety, and treatment, which showed a significance value of (P < 0.05). The findings demonstrated that the treatments had distinct impacts as stimulators and inhibitors for certain elements. Specifically, the application of 120 kg/ha? 1 negatively affected the levels of particular elements, such as Ca mg/kg? 1 , in loam clay and sandy soil. The statistical analysis of trace microelement variance did not show a significance value (P > 0.05) when considering the year factor, which supported the data analysis`s reliability and accuracy. In summary, to enhance the nutritional value of sorghum grain and supply nutrient-rich food choices for individuals, consider factors such as fertilizer response, nutrient uptake by grain, element mineral accumulation, and advisory variety. Additional research could enhance the nutritional properties of sorghum to provide the required dietary stuff, such as grain processing, which can render sorghum a proper addition to a healthy and balanced human diet.

Cím:Revealing Consequences of the Husking Process on Nutritional Profiles of Two Sorghum Races on the Male Sterility Line / Maha Khalfalla, László Zsombik, Zoltán Győri
Dátum:2024
ISSN:2304-8158
Megjegyzések:The male sterility line is a vital approach in the genetic breeding of sorghum. The husking process affects the grain's nutritional composition, emphasizing the intricate relationship between genetic enhancement and dietary requirements. The current study assessed the influence of the Husking Fraction Time Unit (HFTU) process, which was set at 30 (S) and 80 (S) time units per second (S). The study assessed the impact of the (HFTU) process on fifty-one inbred line sorghum race varieties, which implied diverse nutritional profiles considering the pericarp color variations. The assessment of the nutritional profile involved dry matter, total protein, and minerals (P, K, S, Ca, Mg, Na, Fe, Zn, and Mn). The variety groups showed a significance value of p ? 0.05, indicating the study hypothesis's truth. While results demonstrated substantial impacts implied by the Husking Fraction Time Unit (HFTU) technique, the occurrence was noted when the dry matter percentage was increased in the husked products, specifically the endosperm (grits) and bran. Conversely, the protein variation percentage between the bran and endosperm (grits) for the S. bicolor race was calculated at 33.7%. In comparison, the percentage was 11.8% for the Kafirin race. The 80 (S) time unit, on the other hand, had an observable effect on the mineral reconcentration when the Kafirin race had he highest averages of K mg/kg?1, Ca mg/kg?1, and Fe mg/kg?1, which were 5700.5 mg/kg?1, 551.5 mg/kg?1 and 66.5 mg/kg?1, respectively. The results of this study could benefit breeders and nutrition specialists in developing genotypes and processing sorghum grains, promoting research, and aiding several industrial sectors owing to the grain's adaptability and nutritional properties
