This study aimed to identify and examine the prevalence of Aspergillus species in three types of feed collected from specialized dairy farms and local markets in Chiro town, Dire Dawa, and Harar cities in eastern Ethiopia. A total of 180 dairy feed samples were collected and sown, initially on YES agar and then sub-cultured to AFPA to identify Aspergillus species based on colony color, conidia, vesicle, and phialide features. Additionally, the aflatoxigenic potential of the colonies was tested using CAM-based UV fluorescence. The study revealed that the prevalence of Aspergillus species was 80.6% in dairy feeds with a mean count of 3.04 log10cfu/g. Among the identified species, A. flavus was found to be highly prevalent (80%) in the feed with a mean of 2.73 log10cfu/g (7.45 × 103 cfu/g). Meanwhile, A. parasiticus and A. niger were observed in 73.3% (mean 2.43 log10cfu/g) and 58.3% (mean 1.68 log10cfu/g) of feeds, respectively. Furthermore, the prevalence rates of all Aspergillus species in feeds were not significant (p > 0.05) among the study sites and feed sources. However, the mean count of total Aspergillus (3.47 ± 1.34 log10cfu/g), A. flavus (3.20 ± 1.27 log10cfu/g), and A. parasiticus (2.82 ± 1.41 log10cfu/g) was significantly higher in feeds from Dire Dawa city. Additionally, both the prevalence rates and mean counts of total Aspergillus (37.9% and 3.65 ± 1.16 log10cfu/g), A. flavus (38.2% and 3.26 ± 1.12 log10cfu/g), A. parasiticus (38.6% and 2.98 ± 1.34 log10cfu/g), and A. niger (37.1% and 2.11 ± 1.57 log10cfu/g) in total mixed ration were significantly higher (p < 0.05) than in other feed types. Out of the screened Aspergillus colonies, 81.42% were found to be aflatoxigenic, with 58.32% belonging to A. flavus and 41.68% to A. parasiticus. Therefore, widespread contamination of Aspergillus species in dairy feeds across the study sites raises food safety and public health concerns, which highlights the urgent need for stringent measures in feed quality control to curb its prevalence and the risk of aflatoxin exposure.

Sorghum and pearl millet have adapted to the socioecological environment in the dryland of West Africa and have been the staple crops for many years. Engaging key stakeholders and improving the sorghum and pearl millet breeding process is essential to addressing the evolving demands of end-users and environmental conditions. Unlike most trait preference studies focusing on men and women farmers’ trait choices, we examined sorghum and pearl millet key value chain actors (VCA), including producers, processors, traders, and consumers. We identified their preferred traits of varieties that need to be mainstreamed into the breeding pipelines. Drawing on the past efforts and experiences of the sorghum and pearl millet breeding programs from the last 30 years, the study was designed to integrate gender equality in sorghum and pearl millet breeding decisions and traits prioritization in West Africa. This process was implemented in phases, leading to the drafting of gender-responsive and client-oriented product profiles. The paper elicited an understanding of how the roles and interests of sorghum and pearl millet VCA influence their varietal choice and adoption decisions. The study found both differences and similarities in the trait preferences of the men and women VCA. Most women, mainly in the production and processing nodes, prefer varieties with specific food and grain quality traits, while men prioritize grain yield and biotic stress resistance traits. Even though both men’s and women’s varietal choices align with their roles in production and consumption, grain yield was commonly desired across gender, crop, and value chain segments. The findings revealed that the gendered interest of actors in the crops’ value chain determines their choice of variety. Gender responsiveness requires identifying and understanding the needs and choices of the sorghum and millet VCA and mainstreaming these into the breeding pipeline. The approach employed in the study elicits the understanding, roles, and interests of the various actors and how these factors influence men’s and women’s decisions to adopt a crop variety. All major stakeholders should co-develop product profiles for the variety being developed to enable co-ownership, increase adoption, and improve gender equity in agricultural technology development and deployment.

Inclusion effect of different amount of jack mackerel meal (JMM) in the diets substituting 50% fish meal (FM) with corn gluten meal (CGM) on growth, feed availability, biochemical composition, plasma, and serum chemistry of olive flounder (Paralichthys olivaceus) was elucidated. Seven experimental diets were formulated. The control (Con) diet contained 60% FM. Fifty percent of FM in the Con diet was substituted with CGM, and then 5, 10, 20, 30, 40, and 50% JMM were added at the expense of FM to formulate the CJ5, CJ10, CJ20, CJ30, CJ40, and CJ50 diets, respectively. All formulated feeds were assigned to triplicate groups of fish. A total of 420 juvenile fish averaging 18 ± 0.01 g (mean ± SEM) was uniformly divided into 21, 50-L tanks, with 20 fish per tank. Fish were carefully hand-fed to satiation for 8 weeks. The weight gain of olive flounder fed the Con diet was significantly (p < 0.001) higher than that of fish fed the CJ5, CJ10, and CJ20 diets, but not significantly (p > 0.05) different from that of fish fed the CJ30, CJ40, and CJ50 diets. Olive flounder fed the Con diet achieved significantly (p < 0.001 and p < 0.04) greater specific growth rates (SGR) and feed consumption than those of fish fed the CJ5 and CJ10 diets, but not significantly (p > 0.05) different from those of fish fed the CJ20, CJ30, CJ40, and CJ50 diets. However, there were no significant (p > 0.05) differences in feed utilization, proximate composition, amino acid profiles, and plasma and serum parameters of olive flounder. In conclusion, incorporation of 30, and 20% JMM are the most desirable treatments in the olive flounder diets replacing 50% FM with CGM based on weight gain, and SGR and feed consumption, respectively. This study will be very helpful to develop low-FM diets for sustainable olive flounder culture.

The adoption of new agricultural technologies is one of the key factors for achieving sustainable agricultural development. With the rapid development of China’s economy and the widening gap between urban and rural areas, it has become the norm for farmers to seek employment outside their home villages. This phenomenon not only changes the lifestyle of farmers but may also affect their attitudes toward and adoption behavior of new agricultural technologies. However, existing research in this field is not yet sufficient. This paper aims to assess the overall impact, heterogeneous effects, and mechanisms of action of migrant work experience on farmers’ willingness to adopt new agricultural technologies.Based on the 8,391 sample data from 243 counties in the 2018 China Labor Force Dynamic Survey (CLDS2018), this paper uses the Linear Probability Model (LPM), Two Stage Least Square (2SLS), Conditional Mixed Process (CMP) methods, and omitted variable test to estimate the impact of migrant work experience on farmers’ willingness to adopt new agricultural technologies. Simultaneously, it explored the heterogeneity in the relationship between migrant work experience and the willingness to adopt new agricultural technologies from the perspectives of gender, age, and educational level. Lastly, the Karlson-Holm-Breen (KHB) model was utilized to analyze the mechanisms through which migrant work experience affects farmers’ willingness to adopt new agricultural technologies.Migrant work experience significantly enhances farmers’ willingness to adopt new agricultural technologies, with the probability of willingness among farmers with migrant work experience being 26.65% higher than that of farmers without such experience. At the same time, compared to female farmers, those born before 1980, and those with primary education or less, this enhancing effect is more pronounced among male farmers, those born after 1980, and those with more than a primary education. Furthermore, it was found that migrant work experience not only directly enhances farmers’ willingness to adopt new agricultural technologies but also indirectly promotes it by increasing capital accumulation, enhancing risk awareness, expanding social networks, and strengthening agricultural cognition, with risk awareness and agricultural cognition playing a larger indirect role.Based on the empirical results, this paper suggests actively guiding farmers with migrant work experience to adopt new agricultural technologies, and encouraging return migrant labor with the intention of resettling in rural areas to engage in agriculture again, to further promote the adoption of new agricultural technologies.

Luteolin (LTL) is the primary active ingredient in honeysuckle, which exhibited wide pharmacological activities, including heat-clearing, detoxifying, anti-inflammatory and anti-oxidant effects. The conventional method for the extraction of LTL consumed a substantial amount of time and organic solvents, and poor selectivity. Therefore, fabrication of novel material with simple preparation process, low cost and excellent selectivity is of great significance for the extraction and enrichment of LTL from honeysuckle.In this system, a novel surface imprinting polymer for luteolin, denoted as Fe3O4@SiO2@MIP, was synthesized using covalent-noncovalent synergistic imprinting strategies. 3-acrylamidephenylboric acid was adopted as covalent functional monomer, deep eutectic solvent (choline chloride/methacrylic acid (ChCl/MAA, 1/2, n/n)) and methacrylic acid as the non-covalent functional monomers, and Fe3O4@SiO2 nanoparticles as the magnetic support. The resultant Fe3O4@SiO2@MIP displayed a uniform morphology, good crystallinity, and excellent magnetic properties. Meanwhile, the binding experiments demonstrated that Fe3O4@SiO2@MIP exhibited high binding performance and the maximum adsorption capacity was 20.97 mg/g. Moreover, the selectivity and reusability behavior of them were satisfactory. In addition, this polymer, serving as an adsorbent, presented practical application potential in separation and enrichment of LTL from honeysuckle.The covalent-noncovalent synergistic imprinting strategy could greatly facilitate the preparation of imprinted nanoparticles for the specific recognition of LTL, providing a valuable approach for the enrichment of LTL in complex samples.

Traditional fermented beverages are a valuable cultural, economic, and social heritage of Latin American societies that deserve to be preserved and strengthened with sustainable development and respect for diversity. Therefore, this article will demonstrate, through scientific literature, the importance for indigenous societies and the nutritional contributions of the most traditional beverages of North and South America.This systematic review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) verification protocol. The study focused on exploring the nutritional information of South and Central American fermented beverages. The search was conducted in the Biomed, PubMed, ScienceDirect, Scopus, Scielo, and Google Scholar databases to identify publications published within the past 15 years.However, the presence of toxic compounds such as biogenic amines and phenols that affect the quality of the product and human health has been detected. In addition, it was found that macro-and micronutrients, vitamins, and microorganisms differ according to the type of raw material used. It was concluded that corn is the most widely used raw material to produce fermented beverages in Latin America. At the same time, Mexico has conducted more research on this product, and most analyses are being carried out on the use of corn in the production of fermented beverages. In addition, several studies have shown that using validated and standardized methodologies to detect biogenic weapons is crucial to ensure accurate identification, effective response, and compliance with legal and security requirements in this critical area.

The goal of public breeding programs is to develop and disseminate improved varieties to farmers. This strategy aims at providing farming communities with superior crop varieties than they are growing. However, the strategy rarely considers the needs and preferences of farmers, especially gendered preferences, failing to solve real field problems by addressing the differences and inequalities prevalent in the farming communities. Our research examines how personal, household, agronomic and ecological characteristics of wheat growers in Bihar, India’s eastern Indo-Gangetic Plains, affect women and men’s wheat trait choices. Data were obtained from 1,003 households where both male and female respondents from the same household were interviewed. We accounted for 23 traits of wheat from a careful assessment of production, environment, cooking quality, market demand, and esthetic criteria. Binomial logistic regression was used to determine women’s and men’s trait preferences. The results imply that gender influences the preferences of wheat traits. Some traits are favored by both women and men, however, in other instances, there are striking disparities. For example, men choose wheat varieties that are well adapted to extreme climate conditions, have a higher grain yield, and produce chapati with a superior taste, while women prefer wheat types with superior chapati making quality, higher grain yield, and high market prices. Other socioeconomic, agronomic, cultural, and geolocational factors have a considerable impact on trait preferences. These human dimensions of traits preferred by women and men farmers are important for trait combinations to develop breeding product profiles for certain market segments.

The agri-food sector has been identified as one of the most significant contributors to environmental degradation and emissions. Thus, in order to respond to the societal demand for cleaner and greener products, in recent years, the food industry has been striving to identify and apply more sustainable practices to minimize the negative impact on the environment. Within the agri-food sector, one of the industries requiring efforts to mitigate its environmental footprint is the tomato processing industry, which represents an important industry within the Italian industrial food processing sector. Efficient utilization of resources and adoption of innovative methods in the production lines of the tomato processing industry can be envisaged as strategic measures to increase sustainability. This study aims to discuss the results of the case study in which an Italian tomato processing company has been analyzed by applying the LCA methodology.Foreground data were obtained from the tomato processing facility located in southern Italy, and Ecoinvent database was the source of background data. The assessment was carried out by SimaPro software using ReCiPe 2016 (V1.03). The feasible conservation strategies in the production line have been evaluated through water-energy nexus simulation by SuperPro Designer® before the implementation, and different scenarios have been evaluated by SimaPro to decrease the environmental load.This study demonstrates that the production of 1 kg of peeled tomatoes and tomato puree leads to greenhouse gas emissions of 0.083 kg CO2 eq and 0.135 kg CO2 eq, respectively. A deeper analysis to evaluate the contribution of the different tomato processing stages indicated that the thermal units are the main ones responsible for adverse effects on the environment, and any improvement in their performance can be seen as an unmissable opportunity. The conservation strategies identified resulted in considerable water (23.4%), electricity (14.7%), and methane (28.7%) savings and, consequently, in 16 and 19% reduction of global warming potential in peeled tomato and tomato puree production lines, respectively. These findings provide new insights for tomato processing companies wishing to adopt more sustainable processing practices, reducing their environmental impact to a considerable extent and improving their economic performance.

Effective and innovative freshly produced preservation methods are paramount for ensuring safe and sustainable food. Edible coatings for fresh dates can provide an additional protective layer to enhance their shelf life and extend marketability. However, the optimum coating requires a high uniformity of coating layer on the fruit. The ultrasonic coating can achieve a more uniform and consistent coating on the fruit surface. Therefore, this study aimed to design, evaluate, and optimize the process parameters of an innovative ultrasonic coating system (UCS) to enhance the shelf life and quality of fresh date palm fruit utilizing gum Arabic as an edible coating. The response surface methodology (RSM) was conducted using Design-Expert software Version 13. The central composite design was employed to determine the influence of eight independent variables, namely, coating time, air flow rate, liquid height above the ultrasonic transducers, liquid temperature, edible gum Arabic concentration, drying time for coated fruit, drying temperature, and storage temperature on the responses which were fruit shelf life, ripe fruit percentage, color changes, and weight loss. The optimization was conducted to determine the optimal solutions for enhancing fruit shelf life and quality. The optimal optimization outcome with the desirability of 0.90 demonstrated that coating fresh date palm fruits with a gum Arabic concentration of 9.58% at an air flow rate of 1.95 m/s, a height of liquid above the ultrasonic transducer of 0.62 cm, a liquid temperature of 40°C, a drying time of 7.4 min, a drying temperature of 30°C, and a storage temperature of 5°C resulted in extending the shelf life of the stored fruits to 65 days with 3.47 ripening percentage, 7.39 color change, and 4.22% fruit weight loss. The validation experiment conducted at the same independent variable levels indicated that the fruit shelf life extended to 60.2 ± 0.5 days, accompanied by a ripening percentage of 3.4 ± 0.4%, a color change of 10.3 ± 0.9, and a fruit weight loss of 5.4 ± 0.9%. The solutions were validated through rigorous experiments on fresh date palm fruit at the Khalal stage. The findings showed a positive response for fruit shelf life with a slight decrease in the percentage of fruit ripe, color change, and weight loss.
