A study on safety evaluation system of cultured foods among alternative proteins

AbstractFood produced by cell culture has been approved in Singapore and the United States. Food safety evaluation systems of Singapore, the United States, Europe, and Korea were reviewed for producing cultured foods with new technologies. In Singapore, Europe, and Korea, safety evaluation of cultured meat is conducted by applying for such evaluation in the Novel Food system. In contrast, in the case of the United States, safety evaluation for cultured meat is conducted by the FDA and the USDA, considering it as an altered product of production methods, not a novel food. Required safety assessment data vary depending on whether the cultured meat is a novel food or a different food with a different production method. Accordingly, the current study presents differences between required documents according to the two distinct perspectives.

Characteristic of Chrome-Tanned and Vegetable-Tanned Goat Garment Leathers

ABSTRACT. Chrome tanning material is still widely used in the tanning process for garment leather production. Its use began to be reduced to overcome its negative environment impact. Vegetable tannin of a mimosa and tara combination was used in this study to substitute chrome tanning material. Garment made from vegetable-tanned leather with a ratio mimosa to tara of 5:13 was compared to garments made from chrome-tanned leather, both the production methods and resulting leather characteristics. To obtain garment leather characteristics, chrome-tanned leather requires auxiliary materials and two fatliquoring steps. Vegetable-tanned leather requires more auxiliary materials and fatliquoring steps (3 steps). Physical test results show that chrome-tanned leather gives better tensile strength, elongation, tear strength, and softness that meet with SNI (Standar Nasional Indonesia or Indonesian National Standard). Meanwhile, garments from vegetable-tanned leather exhibit elongation, tear strength, and softness that meet with SNI. However, adding auxiliary materials and fatliquoring steps in the garment-making process from vegetable-tanned leather is still unable to produce the softness, smoothness, and elasticity of a garment from chrome-tanned leather.

Laser Metal Deposition of Rene 80—Microstructure and Solidification Behavior Modelling

New developments in nickel-based superalloys and production methods, such as the use of additive manufacturing (AM), can result in innovative designs for turbines. It is crucial to understand how the material behaves during the AM process to advance the industrial use of these techniques. An analytical model based on reaction–diffusion formalism is developed to better explain the solidification behavior of the material during laser metal deposition (LMD). The well-known Scheil–Gulliver theory has some drawbacks, such as the assumption of equilibrium at the solid–liquid interface, which is addressed by this method. The solidified fractions under the Scheil model and the pure equilibrium model are calculated using CALPHAD simulations. A differential scanning calorimeter is used to measure the heat flow during the solid–liquid phase transformation, the result of which is further converted to solidified fractions. The analytical model is compared with all the other models for validation.

Analytical Methods to Evaluate RNA Circularization Efficiency.

Circular RNAs (circRNAs) have emerged as pivotal players in RNA therapeutics. Unlike linear counterparts, circRNAs possess a closed-loop structure, conferring them with enhanced stability and resistance to degradation. Ribozyme-based strategy stands out as the predominant method for synthetic circRNA production, by precisely cleaving and promoting the formation of a covalent circular structure. However, there is still a lack of analytical methods that can provide high-throughput and quantitative analysis to facilitate the circRNA vector engineering process. In the report, we detail analytical methods to characterize and evaluate ribozyme-based RNA circularization efficiency. Our approach will capture the attention of researchers interested in optimizing RNA circularization efficiency, as well as those focused on exploring key elements for ribozyme catalytic activity.

Comprehensive analysis of arc methods of 3D printing of metal products: assessment of the efficiency and prospects of using TIG as a heat source

In recent years, additive technologies have become increasingly important for the production of parts with complex geometries, enabling the rapid and efficient creation of objects with different shapes and configurations in industrial sectors such as medicine, aerospace and construction. The focus of the study was the analysis of arc processes for additive manufacturing, particularly through non-consumable electrode welding in an inert gas environment (TIG) and its applications as a heat source. Modern methods of 3D printing metal products, such as SLM (Selective Laser Melting), EBM (Electron Beam Melting), and LMD (Laser Metal Deposition), allow the production of parts with good quality indicators: accuracy, surface roughness, mechanical properties, and others. However, these methods are expensive due to the technological complexity of the equipment, and a weakness of these methods is their low productivity compared to arc methods. The results presented in this article show that the productivity of arc methods in additive manufacturing is several times higher than that of SLM, EBM, and LMD, and arc methods are more cost-effective due to lower equipment costs and reduced energy consumption. The article presents the schemes of arc methods of additive manufacturing. One of the promising directions in the development of hybrid technology, namely the use of the TIG heat source for sintering metal powders, offers an effective way to reduce the cost of additive manufacturing by replacing the laser as a heat source, while allowing the continued use of various types of metal powders, reinforcing materials, and metal-ceramic blends.

Klímasemleges energiatermelés – Kilátások Magyarországon 2024-ben

In order to protect our planet's climate, it is important to reduce humanity's carbon dioxide emissions significantly. The energy sector is one of the most polluting industries, but the rapid spread of renewable energy sources over the past 20 years can significantly contribute to the reduction of carbon dioxide emissions. The study examined which energy sources are used to produce electricity in Hungary, and how the proportion of renewable energy has developed in recent years compared to more polluting energy production methods. There is a strong negative exponential relationship between the share of renewable energy and the carbon dioxide emissions of the energy sector, based on which the carbon dioxide emissions of the energy sector can be significantly reduced by increasing the share of renewable energy. A forecast was made for the renewable share based on past data and the revised state of the National Energy and Climate Plan in 2023, and a linear forecast was made for the energy sector's emissions. There is a strong exponential relationship between the data series. Both models examined in the study had strong explanatory power, but neither model supports the possibility of climate-neutral energy production by 2030.

원삼국~백제 한성기 취락의 저장 양상 변화

In the process of state formation, storage methods can change according to political, economic, and social transformations. This study aims to identify such changes in storage methods, storage amounts, and stored crops by comparing and analyzing various types of archaeological evidence, such as crop remains, pottery, storage pits, and above-ground structures from sites of the central region of the Korean Peninsula dating the Proto-Three Kingdoms to Baekje’s Hanseong period. The results of the analysis revealed that, in the Gyeonggi region, the tendency to store crops indoors was weakened by the Hanseong period. However, in major settlements, this tendency persisted, and the use of external storage facilities increased, with rice becom-ing a significant crop for external storage. In the Yeongseo region, the change in indoor storage methods was not as distinct as in the Gyeonggi region, but there was a noticeable change in external storage patterns. Overall, the use of deep storage pits increased, new storage crops were added, and the use of external storage facilities increased somewhat in the Namhan River basin. Analyzing the reasons for these changes based on contemporary contexts, it was found that both the Gyeonggi and Yeongseo regions were influenced by changes in agricultural production methods. In the case of the Gyeonggi region, the in-creased complexity of society, such as the intensification of social stratification and the dif-ferentiation of site functions, also influenced storage strategies.

Impacts of Humic Acid on Growth and Yield of Wheat: A Review

Wheat (Triticum aestivum L.) is a crucial crop, providing 20% of caloric intake for many populations worldwide. Soil organic matter, an essential component of soil, directly influences soil fertility and texture. Humic substances, derived from biomolecules' physical, chemical, and microbiological transformation, are integral to soil humus. Humic acid has become a standard method for enhancing crop growth, yield, and soil fertility. While the effects of humic acid on wheat have been extensively studied, the optimal type and application method for wheat cultivation remain undetermined. This review investigates sustainable wheat production methods using humic acid to mitigate the negative impacts of chemical fertilizers and climate change factors. Research indicates that humic acid significantly increases wheat plant growth parameters: shoot length (18%), root length (29%), shoot dry weight (76%), root dry weight (100%), and chlorophyll content (96%). Moreover, humic acid substantially improves wheat yield and yield components, including spike length (14.66%), number of spikes per square meter (28.73%), number of spikelets per spike (23.52%), and 1000-grain weight (23.90%). As a sustainable organic substance, humic acid application offers a promising approach to improving wheat production. This method could help meet the food demands of the growing global population, particularly in countries like Afghanistan, where food security is a pressing concern.

The prospects of the food and agro-food sector in the structure of the economic management system are related to global and national trends in the development of agriculture, food industry and effective management of these industries. The growing demand for environmentally friendly products forces companies and farmers to implement sustainable production methods. This includes reducing greenhouse gas emissions, using water and resources efficiently, and moving to organic agriculture. Environmental standards are becoming important in ensuring the competitiveness of products on the domestic and international markets. Automation and digital technologies are rapidly penetrating the agri-food sector. Precision farming technologies, artificial intelligence, drones and satellite systems allow for increased production efficiency, improved resource management and reduced costs.In addition, digital platforms help to optimize supply chains and improve interaction between market participants. There is an increasing focus on food safety due to increased regulation by governments and international organizations. This requires agri-food businesses to invest in quality control systems and meet international standards such as HACCP. The increase in the export of food and agricultural products is an important factor in the economic development of many countries. This requires diversification of sales markets, improvement of logistics infrastructure and adaptation to the requirements of foreign markets.In addition, supporting local producers through government subsidy programs can strengthen the domestic market. The concept of a closed-cycle economy involves minimizing waste and maximizing the use of resources at each stage of production. In the food sector, this may include using waste as raw material for fertilizer or energy production. Small and medium-sized businesses in the agri-food sector can play an important role in ensuring food security and sustainable development of rural areas. Government support programs, access to finance and educational programs can help strengthen this sector. Climate change directly affects the food sector, causing unpredictable weather conditions that can reduce harvests and increase the risk of production losses. Adapting to these changes requires the introduction of new technologies, genetically modified crops, and risk management programs. At the global level, more and more attention is being paid to food security - ensuring a stable food supply. This includes the development of the agro-industrial complex to reduce dependence on imports, increase food reserves, and develop infrastructure for storage and transportation
