This study assessed the exposure risk to ochratoxin A (OTA) and aflatoxins (AFs) from 18 samples of selected staple foods (maize, millet, groundnut) and 56 fresh cow milk samples collected from across Ghana. The foods were sampled simultaneously to maximise comparability, and at two timepoints in March/April (during the dry season) and July/August (during the rainy season) to assess the effects of duration of storage and seasonal conditions on the mycotoxin levels as measured by high-performance liquid chromatography. The margin of exposure (MOE) approach was used to assess the exposure risk from consumption of the sampled foods. Each of the sampled staples was contaminated with OTA (0.19-3.11 ng/g) and at least one AF (0.75-13.05 ng/g B₁, ND-12.12 ng/g B₂, 0.1-9.95 ng/g G₁, ND-16.78 ng/g G₂). Up to 67% had contamination above European Food Safety Authority (EFSA) maximum limits, and 50% were above Ghana Standards Authority (GSA) limits. The fresh cow milk samples were contaminated with AFM1 in the range of 0.05-1.49 ng/g, with 95% above EFSA limits and 36% above GSA limits. Aflatoxin contamination in the staples was high, particularly in July/August when the wet conditions may have adversely impacted the handling and storage of farm produce. Variation in AFM₁ between the two sampling periods mirrored total aflatoxin in the staples, suggesting that even if dairy cattle were grazing in open pasture and not being rationed on stored feed, then there was a high environmental presence of aflatoxigenic fungi. The MOE estimates were ≤ 533.09, far below the safe cut-off of 10,000 for suspected carcinogenic compounds. The high mycotoxin levels indicate a priority risk to child nutrition which relies heavily on cereal mixes based on one or all the three sampled staples. The data from this study underscore the urgent need for interventions to better appreciate and address mycotoxin exposure for enhanced food security and public health in Ghana and across sub-Saharan Africa.</p>","PeriodicalId":319,"journal":{"name":"Food Control","volume":"168 ","pages":""},"PeriodicalIF":5.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11619758/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To accurately detect and provide timely early warnings for OTA contamination (COTA) in food, a novel four-modal nano-biosensor detection system based on MXenes was developed in this work. MXenes is a new family of two-dimensional materials including vanadium carbide (V₂C) MXenes, which has great potential in the field of biosensing and detection due to its large specific surface area, rich surface functional groups, and good chemical stability. By in-situ chemical etching, metal ion intercalation, and synergistic physical exfoliation techniques, V₂C nano-materials (V₂C-NMS) with excellent fluorescence quenching characteristics were synthesized, and V₂C-NMS@ssDNA with excellent peroxidase like activity was constructed by functionalizing V₂C-NMS with adapter. Based on this, a fluorescence/colorimetric biosensor for OTA was constructed, and the fluorescence/colorimetric signal output by the sensor had good linear relationship with COTA, with the detection limit (LOD) as low as 6.77 pg mL⁻¹. Furthermore, a fully connected artificial neural network (FCANN) was developed based on a series of RGB values obtained from the fluorescence/colorimetric mode of the biosensor, and the fluorescence/colorimetry channel of the FCANN could accurately predict the COTA of the sample on-site or remotely in just a few seconds, with the LOD as low as 7.10 pg mL⁻¹.

Herein, a novel “off-on” colorimetric sensor was first established for histamine detection based on Cu²⁺-mediated laccase-mimic activity of flower-like Mn₃O₄ nanoparticles (<strong>Mnf</strong>). This work proved that Cu²⁺ can inhibit the laccase-mimic activity by hindering the electron transfer between <strong>Mnf</strong> and 2,4-DP molecules. Once histamine was present in the system, Cu²⁺ was first consumed due to the coordination with histamine, resulting in the recovery of laccase-mimic activity of <strong>Mnf</strong>. The color of sensing solution can be converted to the corresponding RGB value by a smartphone for on-site detection of histamine in food. The colorimetric sensor has a limit of detection as low as 0.148 μg mL⁻¹, which is comparable to that of most colorimetric methods.

To improve the edible safety of shiitake mushrooms, this study applied radio frequency (RF) energy combined with natamycin to inactivate <em>Aspergillus niger</em> spores, and evaluate the quality changes after the treatment. The results showed that the population of <em>A. niger</em> spores in shiitake mushrooms with different moisture contents (MCs) could achieve a 5-log (CFU/g) reduction after the combined treatment at different temperatures. Weibull distribution (<em>R</em>² = 0.978 to 1.000) provided a better fit for the inactivation kinetics of <em>A. niger</em> spores than Linear model (<em>R</em>² = 0.954 to 0.990) and Logistic one (<em>R</em>² = 0.953 to 0.988). Meanwhile, the three-dimensional inactivation curves were constructed based on the sample MCs, RF heating time, and holding time. In addition, the MCs of treated shiitake mushrooms decreased by 4.12%–7.66% (w.b.) after natural cooling, achieving synchronous drying. There was no significant difference in textural properties of shiitake mushrooms after the combined treatment. The changes in color, structure, rehydration ratio, and total sugar content were affected by the treatment time and temperatures. As one of the main aroma substances, the content of sulfur-containing compounds in shiitake mushrooms after treatment increased compared to that of the control samples. This study indicates that the combination of RF energy and natamycin is feasible for inactivating pathogens in shiitake mushroom and ensuring the safety of their consumption.</div></div>","PeriodicalId":319,"journal":{"name":"Food Control","volume":"170 ","pages":"Article 111053"},"PeriodicalIF":5.6,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142757406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fungal proliferation is a major cause of economic losses during the marketing of fruits and vegetables. While postharvest disease control is typically done with synthetic fungicides, these can lead to fungal resistance, environmental pollution, and potential health implications. Growing consumer demand to reduce chemical use has spurred interest in natural alternatives like plant-derived essential oils, known for their bioactive, antifungal, and antibacterial properties, as well as their low toxicity, safety, and low cost. The objective of this review is to investigate the efficacy of essential oils in inhibiting the main spoilage and pathogenic microorganisms found in fruits and vegetables through <em>in vitro</em> and <em>in vivo</em> studies. This manuscript presents a bibliometric analysis on the topics of essential oil and nanotechnology, together with a review of the nanoencapsulation of essential oils in nanoemulsion, nanoliposomes, and nanomaterials and their applications in fruits and vegetables with the aim of preserving or improving their quality. Additionally, this paper discusses the challenges and perspectives in the research and development of natural fungicides derived from essential oils. Essential oils are promising for controlling microorganisms in fruits and vegetables; however, they require encapsulation to prevent degradation and allow controlled release. Nanoencapsulation enhances their bioactivity, enabling lower doses and greater stability. Edible coatings with essential oils extend shelf life, and nanotechnology offers innovative, eco-friendly solutions.</div></div>","PeriodicalId":319,"journal":{"name":"Food Control","volume":"170 ","pages":"Article 111044"},"PeriodicalIF":5.6,"publicationDate":"2024-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142720522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
