Aflatoxin contamination in corn and peanuts poses significant risks to human and animal health, making effective decontamination essential. Nonthermal Plasma (NTP) treatment has emerged as a promising method for degrading aflatoxin B1 (AFB1), a potent carcinogen. This study investigated the efficacy of NTP at 160 kV and 150 Hz for 1–5 min in degrading AFB1 in corn and peanuts. The results showed that NTP treatment effectively reduced AFB1 concentrations, with corn exhibiting greater susceptibility than peanuts. The degradation followed a Zero-Order kinetic model, suggesting that the degradation rate was independent of AFB1 concentration. Reactive species generated during NTP treatment, including ozone, hydrogen peroxide, and hydroxyl radicals, played a pivotal role in the degradation process. Additionally, the study examined the impact of NTP on the physicochemical properties of the crops, revealing mild changes in nutritional composition, with more significant effects observed in corn. The NTP treatment also altered the texture and microstructure of both crops, enhancing gumminess and roughness, particularly in corn. This research highlighted NTP as a viable, efficient, and environmentally friendly solution for reducing aflatoxin contamination in food products.

Intelligent colorimetric labels offer a promising approach for monitoring food freshness, yet their practical application is limited by poor stability and dye leakage under high-humidity conditions. In this study, bromothymol blue (BTB) and methyl red (MR) dyes were loaded onto chitosan (CS) gelatin (GE) microspheres to prevent dye leakage and improve CO2 sensitivity. The chromogenic microsphere (CGMB) was then embedded in a hydrophobic ethyl cellulose matrix to construct a water-resistant intelligent sensing film. The scanning electron microscopy (SEM) and Fourier-transform infrared (FTIR) results indicated that the colorants were successfully loaded into the microsphere, and dispersed homogeneously throughout the ethyl cellulose (EC) matrix. The composite films incorporated CGMB exhibit enhanced hydrophobicity and high water resistance, also with significantly lower swelling rates than that of GE films. Moreover, the composite films demonstrate higher CO2 permeability compared to traditional CS and GE films and undergoes a linear chromatic transition, allowing for dynamic correlation with indicators such as fruit respiration intensity. Application to kiwifruit, strawberry, and blueberry packaging confirmed that the labels provided accurate, real-time freshness monitoring. These findings demonstrate a robust and leak-free sensing platform that addresses the limitations of traditional water-soluble films and provides an innovative solution for intelligent packaging.

Authenticating the geographical origin of pistachios is crucial to protect premium varieties such as the PDO “Bronte Green Pistachio” from fraud. This study investigates the potential of visible/near-infrared (Vis/NIR) hyperspectral imaging (HSI) combined with chemometric and machine learning methods for discriminating pistachios from different geographical origins. Traceable batches of Pistacia vera L. from Iran, California (USA), Turkey, and Italy (Bronte and non-Bronte Sicily) were analysed in three sample forms: whole kernels, bulk samples, and ground powders using a 400–1000 nm HSI system. Spectral data were processed using Partial Least Squares–Discriminant Analysis (PLS-DA) and Multilayer Perceptron Artificial Neural Networks (MLP-ANN). PLS-DA achieved high discrimination among the four origins, with overall test set accuracies above 98% for bulk and powder samples, and slightly lower accuracies for individual kernels (86%). MLP-ANN models confirmed the high predictive potential, yielding comparable accuracies (>90%), particularly for ground samples (up to 100%). When focusing on the binary classification between Bronte and non-Bronte Sicilian pistachios, PLS-DA achieved satisfactory discrimination only for bulk/powder samples and not for single kernels, despite the high similarity between the two groups, achieving classification accuracies of 100% for Bronte and 97% for non-Bronte pistachios. Pixel-wise classification maps demonstrated the feasibility of spatially resolved origin prediction. The results indicate promising potential for laboratory-based quality control and traceability applications in the nut industry.

The consumption of processed seafood in the European Union has significantly grown, raising food safety concerns, especially for ready to eat products that are consumed without cooking. This growing market interest has driven innovations, including patented fish dry-curing cabinets. Among biological hazards, Listeria monocytogenes is of particular concern in seafood, prompting regulatory scrutiny and the need for predictive modelling to assess its potential growth. This study aims to assess the performance of a model predicting the behavior of L. monocytogenes in vacuum-packed dry-cured fish under dynamic temperature conditions. The fish tested included salmon, swordfish, and tuna, processed following standardized curing and processing methods. A mixture of three L. monocytogenes strains was used for the challenge tests, ensuring a controlled level of contamination. Microbiological and physicochemical parameters, as well as growth dynamics of L. monocytogenes, were measured throughout the shelf life of the products. A dynamic Baranyi model coupled with a secondary cardinal model was employed to simulate the bacterial growth under varying temperature profiles, utilizing established equations to predict microbial behavior. Initial water activity (aw) and pH values showed stability throughout the study period. L. monocytogenes exhibited growth in salmon and swordfish, while it declined in tuna, probably due to unfavorable aw conditions (0.904 ± 0.010). The model demonstrated good predictive accuracy, with the majority of predictions (88.89 % for salmon and 77.22 % for swordfish) falling within an acceptable prediction zone. This study provides valuable insights into the growth dynamics of L. monocytogenes in dry-cured fish products. The evaluated predictive model can be applied by seafood producers to assess L. monocytogenes risk and make informed decisions about dry-cured fish products shelf life and storage conditions.

Albino green tea, a premium tea product characterized by delicate fresh-green aroma profile, demonstrates pronounced vulnerability to quality deterioration during storage. While temperature and duration are known to impact tea stability, the precise mechanisms governing aroma alteration and the key volatile compounds responsible for stale odor development remain poorly characterized. This systematic investigation elucidates the critical storage parameters and identifies the principal volatile organic compounds (VOCs) associated with sensory deterioration in albino green tea during prolonged storage. As results, elevated temperature is confirmed to be important factor for development of stale odor in albino green tea during storage. Accelerated shelf-life testing indicated that shelf-life of 160 days for storage at temperature of 30 °C, 80 days for storage at 40 °C. According to the Q10 model, Q10 = 2.0 was calculated, and the theoretical shelf life was predicted to be 320 days under 20 °C conditions. A total of 18 volatile compounds were identified as key contributors to the stale odor in albino green tea during storage, including alcohols, alkanes, ketones, aldehydes, pyrroles and derivatives, esters and furans. These stale-associated volatiles display characteristic fruity, sweet, waxy and woody notes, which originated primarily through pathways of glycoside hydrolysis, carotenoids degradation, Maillard reaction and lipid oxidation.

Rapid and ultra-sensitive detection technologies are pivotal for ensuring food safety and public health. While traditional methods like PCR and ELISA are stalwarts, they often lack the adaptability required for rapid, on-site screening. Dynamic nucleic acid nanotechnology, particularly the DNA walker strategy, has emerged as a transformative paradigm in this landscape. By exploiting the programmed, directional motion of molecular walkers, this platform achieves dynamic cascade signal amplification, enabling attomolar-level sensitivity and superior specificity. Here, we present a critical review of DNA walker-driven nanosensing tailored for food safety. We dissect the fundamental design principles, ranging from walker kinetics and track construction to diverse signal transduction modalities. Furthermore, we systematically evaluate recent breakthroughs in monitoring critical contaminants, including foodborne pathogens, biotoxins, agrochemical residues, and heavy metals. Crucially, we address the translational bottlenecks regarding stability in complex food matrices and fabrication standardization. The review concludes by outlining future trajectories toward smart, multiplexed, and field-deployable biosensing systems, providing a roadmap for leveraging DNA walkers to revolutionize next-generation food safety diagnostics.

This study used a quantitative microbial risk assessment framework and developed a risk-based management approach aimed at reducing product nonconformity. The applicability of this approach was demonstrated in a case study of a Taiwanese alfalfa sprout supply chain, focusing on Listeria monocytogenes control. Primary data on cross-contamination rates and time–temperature profiles were obtained. Initial bacterial counts, prevalence, and growth models were derived from secondary data. Cross-contamination experiments indicated that rates of microbial transfer were 0.72 %–12.77 % from sprouts to contact surfaces and were 31.31 %–63.44 % from contact surfaces to sprouts. At baseline, the nonconformity rate (likelihood of exceeding 100 colony-forming units/g) was 1.74 × 10−3 per package of sprouts. Sensitivity analysis indicated that the top three factors influencing this rate were, in order of importance, transportation temperature, initial bacterial count, and storage temperature. Best-case scenario analysis revealed that combined control measures—for example, maintaining temperatures at ≤7 °C during storage and transportation and reducing initial contamination (e.g., through supplier verification and seed decontamination) to <0.5 log colony-forming units/g—minimized the nonconformity rate to a negligible level. Our findings may aid food safety managers in developing data-driven, risk-based management systems to effectively control microbial hazards and improve product safety and quality.

The Black Soldier Fly Larvae (BSFL) oil is a by-product from the animal feed industry. BSFL oil is rich in medium-chain fatty acids, which has led to an increase in demand for pharmaceutical or animal feed industry. This study evaluated the authenticity of BSFL oil and its adulteration with vegetable oils using two portable near infrared (NIR) spectrometers (spectrometer 1 (900 – 1700 nm) and spectrometer 2 (1350–2500 nm)) and Fourier-transform middle infrared (FTIR) spectroscopy (4000–650 cm−1) combined with chemometric methods. Principal Component Analysis (PCA) showed partial separation between pure and adulterated samples, but some mixtures, like BSFL + sunflower and BSFL + corn, overlapped due to similar composition. Data Driven Soft Independent Modelling Class Analogy (DD-SIMCA) was used to authenticate pure BSFL oil, reaching up to 100 % sensitivity and specificity in test set, especially with spectrometer 2 and FTIR. Multi-class PLS-DA models were able to classify BSFL oil and its mixtures, although they showed low classification rates (True Positive Rate (TPR) < 30 %) for BSFL oil adulterated with canola or corn oil, especially using spectrometer 1. Hierarchical PLS-DA models were developed to improve discrimination, reaching better classification rates for all adulterated classes. Overall, DD-SIMCA, PLS-DA and hierarchical models combined with NIR or FTIR spectroscopy are promising tools to detect BSFL oil adulteration in a fast and non-destructive way, with potential applications in quality control and fraud prevention.
