Influence of Solvent Concentration on the Amount of Individual Phenolic Compounds in Apple and Sour Cherry Pomace

Apple and sour cherry pomace, by-products resulting from fruit processing for juice production, were analysed using high-performance liquid chromatography (HPLC) to identify and quantify individual phenolic compounds. In order to determine the most efficient method of extracting these phenolic compounds from pomace, different concentrations of ethanol were used as the organic solvent. The following phenolic compounds were analysed: gallic acid, neochlorogenic acid, (+)-catechin, (−)-epicatechin, chlorogenic acid, vanillic acid, caffeic acid, ferulic acid, sinapic acid, salicylic acid, ellagic acid, rutin, and myricetin. The amounts of these compounds varied depending on the concentration of ethanol used in the extraction process. Neochlorogenic acid, a potent antioxidant, was quantified in apple and sour cherry pomace extracts, showing significant variation with solvent concentration. In apple pomace, the highest amount was found in ethanol 100% (46.44 mg 100 g−1 DW), followed by ethanol 75% (32.09 mg 100 g−1 DW) and ethanol 50% (7.66 mg 100 g−1 DW). In sour cherry pomace, the highest amount was also extracted into ethanol 100% (45.20 mg 100 g−1 DW) and the lowest in ethanol 50% (29.12 mg 100 g−1 DW). Catechin was detected exclusively in cherry pomace, with a maximum yield observed in 75% ethanol (137.86 mg 100 g−1 DW), which was significantly higher compared to the other phenolic compounds analysed. The obtained results demonstrate the importance of apple and sour cherry pomace as valuable by-products, with the potential to be used in the production of functional foods.

On-Line Detection Method of Salted Egg Yolks with Impurities Based on Improved YOLOv7 Combined with DeepSORT.

Salted duck egg yolk, a key ingredient in various specialty foods in China, frequently contains broken eggshell fragments embedded in the yolk due to high-speed shell-breaking processes, which pose significant food safety risks. This paper presents an online detection method, YOLOv7-SEY-DeepSORT (salted egg yolk, SEY), designed to integrate an enhanced YOLOv7 with DeepSORT for real-time and accurate identification of salted egg yolks with impurities on production lines. The proposed method utilizes YOLOv7 as the core network, incorporating multiple Coordinate Attention (CA) modules in its Neck section to enhance the extraction of subtle eggshell impurities. To address the impact of imbalanced sample proportions on detection accuracy, the Focal-EIoU loss function is employed, adaptively adjusting bounding box loss values to ensure precise localization of yolks with impurities in images. The backbone network is replaced with the lightweight MobileOne neural network to reduce model parameters and improve real-time detection performance. DeepSORT is used for matching and tracking yolk targets across frames, accommodating rotational variations. Experimental results demonstrate that YOLOv7-SEY-DeepSORT achieves a mean average precision (mAP) of 0.931, reflecting a 0.53% improvement over the original YOLOv7. The method also shows enhanced tracking performance, with Multiple Object Tracking Accuracy (MOTA) and Multiple Object Tracking Precision (MOTP) scores of 87.9% and 73.8%, respectively, representing increases of 17.0% and 9.8% over SORT and 2.9% and 4.7% over Tracktor. Overall, the proposed method balances high detection accuracy with real-time performance, surpassing other mainstream object detection methods in comprehensive performance. Thus, it provides a robust solution for the rapid and accurate detection of defective salted egg yolks and offers a technical foundation and reference for future research on the automated and safe processing of egg products.

Tactics for Creating Tree Bank for Community Environment and Household Economy in Thailand

This article aimed to present strategies for creating a tree bank. Activities in tree bank plots for sustainable community environmental management and raising the household economy according to the new economic model were studied. The research area is a community that has successfully managed a tree bank and has been praised as a model in 3 regions, including 3 locations: Ban Tham Suea tree bank in Phetchaburi province, Khao Chakan agroforestry tree bank in Sa Kaeo province and Ban Khlong Ruea tree bank in Chumphon province. Data were collected through in-depth interviews. Group interviews were conducted and tree survey plots in the field were prepared. Committee members of the Tree Bank and representatives of the 3 Bank for Agriculture and Agricultural Cooperatives (BAAC), 11 people each, totaling 33 people were purposive sampling. Content analysis and the abundance of plant species were analyzed using the Menhinick (1964). The research results showed that the strategy for creating a tree bank involved group forming of household members with their own land by planting trees in agroforestry plots. The group acquire wood as an asset and use trees as collateral to guarantee loans from financial institutions that are guaranteed by the state. Environmental activities were organized by planting trees of at least 25 perennial trees per rai. 58 plant species as specified by the BAAC were chosen. Nourish the soil with compost made from scraps of leaves and branches. The richness index (R2) analysis showed that the abundance of tree species in all plots was at a high level (R2 =2.5-4.5). In terms of upgrading the household economy, knowledge of the production of firewood and burn charcoal, wood vinegar from trees, wood processing for house construction and furniture products was disseminated by the tree bank by organizing learning center and eco-tourism. Collaborative networks with organizations and educational institutions were built in order to use the tree bank for sustainable development.

Trade openness and growth in a small economy: Evidence from Malawi

AbstractEconomists often debate whether a country should pursue a discriminatory regional trade or the broader multilateral trade expansion. This paper contributes to the discourse by presenting empirical evidence on the impacts of regional and multilateral trade openness on economic growth of expansion in Malawi. Using the ARDL‐EC model and data spanning the period 1995–2020, the estimates show that the impact of multilateral trade openness on the long‐run growth rate is positive and statistically significant. At the disaggregated level, the results show that both intra‐ and extra‐African merchandise trade openness have positive and significant impact on the long‐run growth rate. The evidence also suggests that the impact of a change in the level of intra‐African merchandise trade openness on long‐run growth is larger than that of a similar change in the level of extra‐African merchandise trade openness. Thus, our results suggest that policymakers can pursue both regional and multilateral trade expansions simultaneously to accelerate Malawi's economic growth. To augment the benefits of trade, however, we recommend that policymakers focus on deepening intra‐African trade integration and diversifying the country's export base beyond the primary commodities; and to increase the processing of export products to enhance the dynamic benefits to spur faster growth.

Cooperative-Collective Farm Construction in Kyrgyzstan in 1920-1930 of the XX Century

In accordance with the decision of the party and government, the All-Union Conference of Collective Farms (February 1925) adopted a resolution on the creation of the All-Union Council of Agricultural Collectives (Collective Farms). This all-Union body specially dealt with issues of collective farm development, and collective farming departments began to emerge under agricultural cooperative unions. On the territory of Kyrgyzstan, cooperative and collective farm construction especially intensified, as we have already noted, after the formation of the Kyrgyz Autonomous Region. The activities of agricultural cooperation here were expressed in long-term and short-term lending to members, supplying peasant farms with agricultural implements, organizing sowing of industrial crops, grains, beekeeping and sericulture, marketing of peasant farm products, participation in grain, cotton and raw material harvests. trades, processing of agricultural products.

Gene emrC Associated with Resistance to Quaternary Ammonium Compounds Is Common among Listeria monocytogenes from Meat Products and Meat Processing Plants in Poland.

(1) Background: L. monocytogenes is a food pathogen of great importance, characterized by a high mortality rate. Quaternary ammonium compounds (QACs), such as benzalkonium chloride (BC), are often used as disinfectants in food processing facilities. The effectiveness of disinfection procedures is crucial to food safety. (2) Methods: A collection of 153 isolates of L. monocytogenes from meat processing industry was analyzed for their sensitivity to BC using the agar diffusion method. Genes of interest were detected with PCR. (3) Results: Genes emrC, bcrABC, and qacH were found in 64 (41.8%), 6 (3.9%), and 1 isolate (0.7%), respectively, and 79 isolates (51.6%) were classified as having reduced sensitivity to BC. A strong correlation between carrying QACs resistance-related genes and phenotype was found (p-value < 0.0001). Among 51 isolates originating from bacon (collected over 13 months), 48 had the emrC gene, which could explain their persistent presence in a processing facility. Isolates with the ilsA gene (from LIPI-3) were significantly (p-value 0.006) less likely to carry QACs resistance-related genes. (4) Conclusions: Reduced sensitivity to QACs is common among L. monocytogenes from the meat processing industry. Persistent presence of these bacteria in a processing facility is presumably caused by emrC-induced QACs resistance.

Assessment and Spatio-Temporal Evolution of Marine Fisheries’ Carbon Sink Capacity in China’s Three Marine Economic Circles

With the increasing pressure of resource decline and environmental pollution faced by the green transformation of marine fisheries, marine fishery carbon sinks are an increasingly close link to national strategic interests and economic lifelines. It is, therefore, necessary to explore paths for the enhancement and development of the carbon sink capacity of marine fisheries. Based on the economic data of marine fisheries from 2002 to 2021, this paper measures the capacity and characteristics of marine fishery carbon sinks in provincial areas, applies the kernel density estimation method to depict the dynamic evolution of the distribution of absolute differences in marine fishery carbon sinks, and at the same time, identifies the factors influencing the spatial imbalance in the development of marine fishery carbon sinks as well as the spatial spillover effects. The results show the following: (1) From the total amount, the fishery carbon sink capacity of China’s three marine economic circles has fluctuated and increased over the past 20 years, with obvious differences among different circles, and the marine fishery carbon sink capacity of the eastern, northern, and southern marine economic circles has risen sequentially. This trend corresponds to the economic disparities among the three circles, demonstrating a transition from economic to industrial driving effects. (2) From the spatial point of view, the fishery carbon sink capacity shows a trend of increasing year by year, concentrating in the circles, and overflowing between the circles. (3) The results of a partial derivative test further show that among the main influencing factors of marine fishery carbon sinks, capital, labor, and market openness have direct positive effects on marine fishery carbon sinks, and the direct effect of innovation is the strongest, and the significance of the indirect effect of the three circles is weaker compared to the direct effect and total effect. As a result, the carbon sink of China’s marine fisheries has a large room for improvement, and in order to promote the high-quality development of China’s marine fisheries, it is still necessary to accelerate the circulation of resources within the marine economic circle, accelerate the research of fishery technology, actively develop the carbon sink fishery, and enhance the specialization of aquatic product processing.

Two treatments were conducted in addition to the control, they include the addition of 0.5% black cumin and 0.5% coriander seeds that were added to the yoghurt mish after incubation. The chemical and sensory analysis were conducted during the 2nd, 7th and 15th days of storage. The fat content was significant (P&lt;0.05) higher in the yoghurt mish fortified with black cumin seed, while the total solids, protein, ash and titratable acidity contents were significant (P&lt;0.05) higher in the yoghurt mish fortified with coriander. Moreover, significant (P&lt;0.05) variations were reported for the compositional contents of goat yoghurt mish during the storage period. The best colour score was recorded for the control yoghurt mish, while the best flavor, taste and over all acceptability scores were reported for the yoghurt mish fortified with black cumin. The results revealed significant (P&lt;0.05) differences in color and texture between the control and treated yoghurt mish samples. Moreover, the results indicated that all the sensory characteristics of yoghurt mish were significantly (P&lt;0.05) affected during the storage period. This study concluded that fortification of yoghurt mish with coriander and black cumin seeds improve the compositional quality and the taste, flavor and the overall acceptability scores of goat milk yoghurt mish. This indicates the possibilities of processing and marketing of such products.

Pyrometallurgical Reduction of Copper Slag with Biochar for Metal Recovery

Large amounts of slag are generated during pyrometallurgical processing in copper production. Due to the presence of valuable elements, the improper disposal of huge quantities of copper slag produced, results in significant loss of resources as well as environmental issues. Analyses of the copper slag show that it contains valuable metals, particularly copper and nickel. In this work, four biochars were employed as fossil-free reducing agents to recover valuable metals from the slag. Reduction experiments were performed in a vertical furnace at temperatures 1250, 1300 and 1350 °C for 60 min in order to investigate the effect of temperature. Moreover, the effect of time on reduction progress was studied at 1250 °C and the concentrations of CO and CO2 in the off-gas were measured with a gas analyzer. Copper slag was reacted with metallurgical coke for comparison and the products were analyzed with EPMA and LA-ICPMS. The results revealed that reduction rapidly progresses to the formation of metal alloy within 10 min. Valuable metals like copper, nickel and arsenic were the first to be reduced to the metal phase. As reduction time increased, iron was also reduced and combined with the metal droplet. The use of biochar as reductant was shown to be more effective than coke especially at lower temperatures. In addition, thermodynamic modelling was performed with FactSage and HSC and compared with the experimental results. The simulations with HSC showed the sequence of reactions taking place and the calculations by FactSage were in agreement with the experiments.Graphical

Relevance. The agro-industrial complex is one of the key sectors of the country's economy and includes such areas as: agriculture (livestock and crop production), processing of agricultural raw materials, production of fertilizers, chemicals, and feed. The agro-industrial complex works closely with enterprises involved in the transportation, storage, and processing of agricultural products, as a result, any changes in the agro-industrial complex affect the country's economy.The purpose of the study is to assess the impact of the implementation of the federal project of the Russian Federation “Development of industries and technical modernization of the agro-industrial complex” (hereinafter referred to as the Federal Project) on structural changes in the agro-industrial complex.Objectives: consideration of the objectives of the Federal project, its financial support for 2022-2024, analysis and assessment of economic and statistical indicators, identification and consideration of current problems within the framework of the project.Methodology. The information base of the study consisted of official regulations, works of domestic researchers in the field of agriculture, collections of articles with collective authors, articles from magazines, statistical data, official websites of relevant departments and ministries.Results. There are many problems in the development of the Russian agro-industrial complex, but there are also many promising areas for its development. These prospects are determined primarily by state policy in the field of supporting agriculture, the goal of which is the development of Russian farmers and increasing their role in the domestic and foreign markets.Conclusions. A promising direction for the development of the agro-industrial complex is the revision of the entire financing system in order to provide business executives with funds for the purchase of mineral fertilizers, fuels and lubricants, materials, and high-quality feed in the volumes necessary for efficient production. Also requiring attention are such pressing issues as increasing wages for agricultural workers, which will attract young specialists to the village and, thereby, resolve the issue of shortage of qualified personnel.

Transformative changes are needed to support socio-bioeconomies for people and ecosystems in the Amazon.

Current social-technical and political conditions threaten the integrity of the Amazon biome. Overcoming these lock-ins requires structural transformations away from conventional economies towards 'socio-bioeconomies' (SBEs). SBEs are economies based on the sustainable use and restoration of Amazonian ecosystems, as well as Indigenous and rural livelihood systems in the region. They include sustainable eco-tourism as well as diversified production and innovative processing of fruits, nuts, oils, medicines, fish and other products deriving from socio-biodiversity. Using a sustainability transitions perspective, we argue for multi-scalar policy changes to sustain, enhance and scale-out and scale-up SBE initiatives. To nurture niche SBE acitivities, we advocate for improvements in infrastructure, value chains and social organizations. To dismantle structural barriers, we call for an end to harmful subsidies, greater representation of marginalized communities in territorial planning, enhanced rural-urban and intersectoral linkages, international collaboration, shifts in demand, and changes in conservation and production narratives. Policies for SBEs must also use clear definitions, participatory processes and a multi-biome approach to avoid perverse outcomes.

Mechanistic insights into combined effects of continuous microwave heating and tremella powder addition on physiochemical properties of Nemipterus virgatus surimi gel

The physicochemical properties of Nemipterus virgatus surimi gel were investigated, with tremella powder (TP) at concentrations ranging from 0 to 0.5% (w/w) combined with continuous microwave heating (CMH) using water-bath heating (WBH) as control. Results showed that TP addition (0.1%–0.3%, w/w) could significantly enhance the water holding capacity and reduce whiteness and cooking loss, attributed to the changed lateral relaxation time of water distribution. Notably, at 0.3% TP and 80 °C, the gel strength significantly increased by 96.84%, and the hardness, chewiness, and adhesiveness improved, but the quality of surimi decreased above 0.3% TP. The gel network structure was influenced by protein secondary structure composition, especially for increasing β-sheet in Raman spectra, thus promoting the gel microstructure density and uniform protein distribution. These findings offer insights for enhancing surimi gel quality and broadening tremella application in product processing.

Optimization of mechanical and safety properties by designing interface characteristics within energetic composites

The interfacial structure has an important effect on the mechanical properties and safety of the energetic material. In this work, a mesostructure model reflecting the real internal structure of PBX is established through image digital modeling and vectorization processing technology. The microscopic molecular structure model of PBX is constructed by molecular dynamics, and the interface bonding energy is calculated and transferred to the mesostructure model. Numerical simulations are used to study the influence of the interface roughness on the dynamic compression and impact ignition response of PBX, and to regulate and optimize the mechanical properties and safety of the explosive to obtain the optimal design of the surface roughness of the explosive crystal. The results show that the critical hot spot density of PBX ignition under impact loading is 0.68 mm−2. The improvement of crystal surface roughness can improve the mechanical properties of materials, but at the same time it can improve the impact ignition sensitivity and reduce the safety of materials. The optimal friction coefficient range for the crystal surface that satisfies both the mechanical properties and safety of PBX is 0.06–0.12. This work can provide a reference basis for the formulation design and production processing of energetic materials.

Recent developments in the application of alternative sterilisation technologies to meat products: A review

SummaryMeat is widely regarded as the optimal source of protein for human consumption. However, meat is susceptible to spoilage and microbial contamination throughout processing, transportation and storage stages. Traditional thermal processing techniques are commonly employed in the global meat industry. While these methods ensure microbiological safety, they may also impact the sensory and functional attributes of meat products. To address these limitations, non‐thermal processing technologies are progressively replacing conventional thermal approaches. This review will primarily focus on the potential application of non‐thermal processing technologies as alternatives to traditional methods in meat and meat product processing. Various technologies exhibiting promising performance in this field will be presented. Additionally, the mechanisms, advantages and limitations of these non‐thermal technologies in recent years will be summarised, along with a discussion on the challenges and prospects they present. This study provides an overview of non‐thermal processing technology specifically applied to meat products, emphasising the underlying mechanisms associated with different approaches. By employing diverse technical combinations, it is possible to address existing processing limitations and expand their applicability range. Non‐thermal processing technology demonstrates significant potential for enhancing meat processing practices; however, concerns regarding safety aspects and limited clinical verification about to environmental pollution have impeded its widespread adoption within the food industry.

Supply and demand of lithium in China based on dynamic material flow analysis

Lithium demand in China has grown rapidly with the popularization of computer, communication and consumer electronic (3C) products, electric vehicles (EVs), and other products. As an important part of the global processing of lithium products, China still relies on importing a vast majority of raw lithium materials, which significantly affects the supply fulfillment of China's lithium market. Therefore, this study used MFA to analyze the supply and demand characteristics of China's lithium trading market from the trade material flow between 2000 and 2021 and industrial material flow between 2017 and 2021 by quantizing trade and industry data. The results showed that the import of lithium in China is mainly concentrated on lithium carbonate, which is the raw material for power batteries, and the import of lithium accounts for 72.5 % of the consumption in China, about 75.2 % of carbonate lithium is used for batteries. Given the expanding EV market, the demand for lithium in China increases rapidly. In addition to a stable supply of lithium imports, secondary lithium recovered from EoL batteries is expected to become an important lithium supply source.

Operational parameters optimization of convection air-drying with ultrasound pretreatment of Cyperus rotundus L. tubers by RSM

Drying is an important step in the postharvest processing of agricultural products, as it allows the product to be preserved by reducing water activity to safe values, which stops microorganism growth and enzymatic reactions. In this context, the objective of this study was to assess how various drying temperatures, combined with ultrasonic pretreatment, affect drying rates and essential oil production. Assays were conducted according to a Central Composite Rotational Design, considering two factors with the following intervals: duration of the ultrasonic bath from 0 to 40 min, drying air temperature from 40 to 70 °C. The optimization was carried out using Response Surface Methodology (RSM). The essential oil was extracted by hydrodistillation and its constituents were identified by gas chromatography coupled to mass spectrometry. Histochemical analyses of fresh tubers were performed. The Midilli model was the one that best described the drying kinetics of Cyperus rotundus in all treatments. The drying time of C. rotundus tubers was dependent only on temperature (decreasing linear effect), it was possible to describe the variation in drying time as a function of temperature. It was not possible to adjust a model for ultrasonic bath time or drying temperature that would optimize both essential oil yield and the drying time of C. rotundus tubers. However, in this study, shorter drying times were observed compared to previous studies on C. rotundus tubers drying in the shade at room temperature. A total of 29 chemical constituents have been identified in the essential oil extracted from C. rotundus tubers, of which the majority are: 3,4-dimethyl-3-cyclohexen-1-carboxaldehyde (19.23%); caryophyllene oxide (17.63%); and α-cyperone (9.54%). Histochemical analyses of C. rotundus tubers showed the presence of starch, phenolic compounds, and lipids.
