Data on the relationships between specific traditional storage management practices of sorghum and mycotoxin contamination are rarely available in Ethiopia. The aim of this study was to investigate current sorghum storage management practices in major sorghum producer locations in Northwest Ethiopia and their relationships with mycotoxin contamination. Sorghum storage management practices of 120 farmers were surveyed, the occurrence of multiple mycotoxins in samples from their stored sorghum was determined, and potential relationships between the traditional storage management practices and mycotoxin contamination were analyzed. Samples were analyzed using UPLC-MS/MS for 33 different mycotoxins. About 88% of the samples were contaminated with at least one mycotoxin. The detected mycotoxins belong to one of the four mycotoxin categories, produced by <em>Aspergillus</em> spp, <em>Fusarium</em> spp, <em>Penicillium</em> spp, and <em>Alternaria</em> spp. From the total, 3%, 7%, and 3% of the samples were contaminated with aflatoxins, ochratoxin A, and zearalenone, respectively, above the EU regulatory limits. The measured concentrations that bypassed EU regulatory limits were 9.14, 18.34 and 29.13 (μg/kg) for total aflatoxins, 5.31, 12.50, 14.94, 15.77, 32.94, 56.81, 58.07 and 112.59 (μg/kg) for Ochratoxin A, and 123.48, 238.43 and 431.78 (μg/kg) for Zearalenone, respectively. Logistic regression showed relationships between the traditional storage management practices with mycotoxin contamination. The age and the experience of the Main Person Responsible for Storage management (MPRS), the placement of the storage structure, and the insecticide application showed negative relationships with multi-mycotoxin contamination. On the other hand, the educational status of the MPRS and the type of storage structure showed positive relationships with mycotoxin contamination. Therefore, it is recommended that farmers receive training in proper sorghum storage management to further reduce the mycotoxin contamination in the grain.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102535"},"PeriodicalIF":2.7,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143181475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite efforts to increase yields, poor practices before and after harvesting often lead to losses that threaten food and nutrition security. These losses also waste vital resources such as water, land, and energy used in crop production. It is argued that reducing losses is more important and cost-effective than simply focusing on increasing production. Understanding the factors, locations, and types of losses is crucial for developing effective control strategies, requiring specialized research and analysis. Raising public awareness about the causes and prevention of agricultural produce losses is essential. While many studies focus on fruit and vegetables, grain crop losses are often overlooked despite accounting for over 50% of caloric value. This study aims to overview agricultural crop losses, specifically in grain crops, by examining the different types of losses that happen before, during, and after harvesting. This evaluation encompasses a comprehensive look at the supply chain, identifying points where losses occur and investigating their causes. The study also explores potential strategies to mitigate these losses, highlighting effective solutions to improve efficiency and reduce loss throughout the grain supply chain. Taking a holistic approach to this issue can improve food and nutrition security, reduce financial losses, and establish a more sustainable and efficient agricultural system.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102547"},"PeriodicalIF":2.7,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143104917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the prevalence of AFs in 21 samples of leftover flat bread/<em>chapati</em> samples from different dairy farms of South Punjab, Pakistan was evaluated. Furthermore, the impact of different preventive practices on fungal growth and aflatoxin levels in leftover flat bread/<em>chapati</em> during 21-day storage was investigated. Eighteen samples (86%) of leftover flat bread/<em>chapati</em> collected from the dairy farms were found to be contaminated with total AFs at mean levels ranging from 1.65 to 37.20 μg/kg, among which 29% were found to have total AFs higher than the maximum permitted levels adopted in the European Union and the United States (20 μg/kg). Traditional, open-air storage practice leftover flat bread/<em>chapati</em> led to the highest fungal growth, while hermetic sealing (HS) in low density polyethylene (LDPE) bags effectively minimized fungal growth. HS combined with the addition of neem leaves and silica beads inside LDPE bags at percentage inclusions of 5–10% showed the most significant protective practice against fungal proliferation and AFs production. These data highlight the need for proper storage practices to avoid fungal contamination and AF production in leftover flat bread/<em>chapati</em> in dairy farms.

Mechanical damage significantly impacts both their edibility and commercial value. Therefore, it is crucial to predict and evaluate potential damage in fruit production and logistics. In this study, the effects of compressive damage on apple fruits were investigated. A multi-scale finite element analysis (FEA) model, incorporating both the peel and flesh, was developed to analyze the impact of compression distance and storage time (1, 3, 5 days) on internal stress variations within the fruit. The results indicate that, when compressed at displacements of 2 mm, 4 mm, and 6 mm, the maximum equivalent stress in the flesh and peel reached 0.31, 0.52, 0.68 MPa, and 0.19, 0.30, 0.49 MPa, respectively. The force-displacement curves from both experimental data and finite element method (FEM) simulations for apples stored over different durations showed high correlation coefficients of 0.9911, 0.9931, and 0.9955, respectively, confirming the model's ability to accurately simulate real compression scenarios.

The results demonstrated that hazelnut proteins with varying degrees of oxidation exhibited distinct effects on the stability of O/W emulsions. Mild and moderate oxidation resulted in an increase in the absolute ζ-potential, surface hydrophobicity, endogenous fluorescence intensity, centrifugal stability, emulsification index, adsorbed protein content, and viscosity of the emulsions, it caused a decrease in particle size and turbidity, ultimately leading to an improvement in the physical stability of hazelnut protein emulsions. Electrophoresis results demonstrate that proteins with moderate oxidation exhibit increased flexibility, which contributes to the development of a more compact interfacial structure and improved stability of emulsions. The decrease in viscosity as the shear rate increases suggests that hazelnut protein emulsions are characteristic of shear-thinning systems. Additionally, frequency scans reveal that all emulsions display an improved elastic structure in both the mid-and high-frequency ranges. Oil oxidation is an unavoidable process that occurs over extended periods of storage. However, emulsions containing a moderate level of protein oxidation exhibit reduced levels of oil oxidation products in comparison to other emulsions. This characteristic contributes to the stabilization of oil-in-water (O/W) emulsions.
