Megjegyzések:	The study focused on utilizing lemon grass straw to generate cellulose through the process of delignification, which involves the removal of hemicelluloses, followed by bleaching. The study involves the microwave-assisted alkali extraction, followed by characterizing the extracted material. At microwave power of 540 W using 8 % NaOH for 3 min for lignin removal and 540 W for 2 min for bleaching showed the maximum yield of 37.46 %. Fourier transform infrared spectroscopy is employed to analyze the physical properties of extracted cellulose, namely the hydroxyl (OH), carbonyl (C=O), C-H bonds, C-O and C-C bonds, and glycosidic linkage (C-O-C) within the cellulose polymer chain. The extracted cellulose exhibited excellent thermal stability, as indicated by its high breakdown temperature. The X-ray diffraction (XRD) analysis revealed prominent peaks at 14.8?, 16.5?, and 22.5?, demonstrating the presence of crystalline cellulose. The crystallinity index value of 70.02 % further confirmed the crystalline nature of the extracted cellulose.

Megjegyzések:	The increasing quest for the minimally processed foods and demand for nearly fresh foods from the consumer segment has paved the way for the emergence of Non thermal processing technologies. A significant development in the food and bioprocessing sector is the evolution of cold plasma processing which is renowned for its preservation efficacy and shelf life enhancement of foods. The growing application of cold plasma has expanded its role in the modification of food biomolecules in order to meet the diversified requirements of food industries for varied applications. The previous investigations have shown its proven benefits in the microbial destruction, enzyme inactivation, modification in the polymer matrices for food packaging etc. Cold Plasma processing is a promising candidate with the benefit of minimizing the negative effects of thermal processing to the food matrix particularly to the protein molecules which are prone for denaturation at relatively higher temperatures. Proteins which are the polymers of amino acids are highly valued with commercial importance because of the techno-functional properties they possess along with its nutritional potential. The cold plasma induced modification of proteins are known to enhance the functionality of native proteins by altering the structure-functional relationship. The interaction of cold plasma and its reactive species on the amino acid structure will lead to a functional change in the protein molecule and can propel its application in diverse fields like 3-D printing, novel gel structures formation, thermostable foams and emulsions, improved solubility and enhanced organoleptic property. Considering the growing importance of the process technology, review aims to shed light on the impact of cold plasma processing on the protein modification and its associated molecular understanding with its future path of research. Future scope of considerations along with the challenges are also discussed which need to be taken on priority to get the potential benefit and commercial realization of the technology.

Cím:	Precision agricultural technology for advanced monitoring of maize yield under different fertilization and irrigation regimes: A case study in Eastern Hungary (Debrecen) / Adrienn Széles, László Huzsvai, Safwan Mohammed, Anikó Nyék, Péter Zagyi, Éva Horváth, Károly Simon, Sana Arshad, András Tamás

Megjegyzések:	Precision agricultural (PrA) technology relies on the utilization of special equipment to access real time observations on plant health status, chlorophyll, nitrogen content, and soil moisture content. In this research new PrA technology (i.e., SPAD (Soil Plant Analysis Development), and UAV-based NDVI (Unmanned Aerial Vehicle-based Normalized Difference Vegetation Index) were used to monitor maize yield based on different filed trials in eastern part of Hungary. Our study aimed to examine the utilization of PrA technology specifically SPAD and UAV-based NDVI measurements for monitoring maize GY under irrigated and rainfed experimental setups in Hungary with varied nitrogen treatment for the year 2022. The results showed that the SPAD increased in all treatments (14.7 %; p < 0.05) from V6-V8 in the rainfed treatments, decreased significantly (p < 0.05) by 13.9 % (R1) and 30.6 % (R3). However, implementation of irrigation significantly increased the SPAD values in majority of treatments. Also, results reveal that, under irrigated and rainfed conditions the highest UAV-based NDVI value (0.703, 0.642) was obtained in V12 (A120 treatment) and highest NDVI value (0.728, 0.662) was obtained in Vn (A120 treatment). Remarekedly, irrigation led to significant differences (p < 0.05) of UAV-based NDVI values compared with none irrigated. On the other hand, implementation of 120 kg N ha?1 before sowing led to highest GY, especially under irrigated conditions (8.649 Mg ha?1). The overall mean GY under rainfed treatment was 6.256 Mg ha?1, while under irrigated treatment it increased by 37.2 % and reached 8.581 Mg ha?1 (p < 0.05). In conclusion, PrA technology will support farmers in making informed decisions regarding fertilization strategies and timing, which will in turn maximize yield and minimize risk.

Cím:	Evaluation of bioactive compounds in leaf and root of five beetroot varieties / Takács-Hájos Mária, Vargas-Rubóczki Tímea
Dátum:	2022
ISSN:	2666-1543
Megjegyzések:	Natural compounds are essential in modern nutrition for preventing chronic diseases in the human body. The bioactive substances in 5 beetroot cultivars' leaves and roots were evaluated in the experiment, providing an answer to which stage (60th, 85th, and 105th) of the vegetation is most suitable for fresh consumption. The results show that the polyphenol, flavonoid, and FRAP levels in the leaf and root samples varied throughout the vegetation period. The 60-day old leaf samples of 'Libero' had the highest total polyphenol content. The flavonoid content showed a similar trend. Furthermore, the highest FRAP value was found in leaf samples from 'Libero' and 'Pablo F1' that were 60 days old. In 85-day-old plants, the polyphenol content of the leaves was significantly reduced. On day 85, however, a value was slightly higher in the roots. These findings support the nutritional value of the 85-day-old beetroot (leaves and 3-5 cm diameter roots). At the 85-day stage, the leaf and root had a relatively low nitrate content (10-70 mg/kg). However, higher nitrate content was detected at the end of the growing period (105 days). The experiment demonstrated that beet leaves can be used as a component of fresh salads on the 60th day of the growing season because the amount of bioactive substances (polyphenols, flavanoids) is highest at that time. By the 85th day of growth, the root had grown to 4-5 cm in diameter, and the tissue structure of the leaves is edible (it can be eaten raw), making it ideal for batch sales. By the end of the growing season (day 105), the root has been strengthened, and its bioactive substances have been reduced by up to 1/3 compared to the previous state (85 days), resulting in a decrease in the amount of bioactive substances.
