Leftover flat bread/<em>chapati</em> is a traditional staple food commonly consumed by the people of South Asian region. AFs-contaminated leftover flat bread/<em>chapatis</em> are usually turned into animal feed, which warrant concern about the secondary effects of AFs in humans. 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. Further research should be conducted to optimize HS methods in combination with selected medicinal plants and chemical compounds to ensure the safety and regulatory compliance of leftover flat bread/<em>chapati</em> during storage.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102544"},"PeriodicalIF":2.7,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143105048","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}

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 integration of experimental results with finite element methods provides a more comprehensive understanding of the mechanical properties and damage relationships in apples, offering significant insights for predicting internal damage and developing new systems to prevent fruit damage.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102543"},"PeriodicalIF":2.7,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143181471","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}

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. In conclusion, hazelnut proteins that have undergone moderate oxidation exhibit beneficial effects on emulsion stability, interfacial properties, and lipid oxidation.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102534"},"PeriodicalIF":2.7,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143105372","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}

Seeds were stored at three different temperatures (15 °C, 20 °C, and 25 °C) for periods ranging from 0 to 360 days, with assessments conducted at 90-day intervals. The results demonstrate that UV-C treatment plays a significant role in maintaining seed quality throughout storage. Seeds exposed to 20 min of UV-C radiation and stored at 15 °C retained the highest moisture content and showed the least color degradation, particularly in terms of lightness (<em>L∗</em>) and chroma values. In addition, UV-C exposure positively influenced the mineral composition, particularly calcium and potassium content, which showed increased levels under UV-C treatments. However, magnesium and zinc levels were more variable, with some reductions observed over extended storage durations. The optimal conditions for preserving seed quality were found to be 20 min of UV-C exposure combined with storage at 15 °C for up to 270 days.

Moreover, the study developed and validated a method to determine the actual residues of EF in both date varieties using cooled methanol for extraction and analyzed by gas chromatography-mass spectrometry in selected ion monitoring.

Using proximate composition analysis as per the Association of Official Analytical Chemists (AACC) standards, the results showed that after six months of storage, PICS bags preserved the highest germination energy (87.83%), whereas underground pits had the lowest (39.79%).
