The treatment protocol involving PEF and USN led to positive outcomes, indicating reductions in OTA by up to 50% and Enniatin B (ENNB) by up to 47%. Using the USN and PEF together resulted in lower reduction rates, up to a 37% decrease. In closing, the combined effect of USN and PEF processes demonstrates potential for reducing mycotoxins in fruit juice that is blended with milk.

Erythromycin (ERY), a macrolide antibiotic commonly applied in veterinary medicine, is used to treat animal diseases or to promote animal growth through its incorporation into the animal feed. The persistent and unreasonable utilization of ERY could leave behind traces in food derived from animals, potentially leading to the rise of drug-resistant strains, thus posing a risk to human health. This study details a highly sensitive, specific, robust, and rapid fluorescence polarization immunoassay (FPIA) for quantifying ERY in milk samples. Five ERY tracers, each uniquely structured with fluorescein, were synthesized and combined with three monoclonal antibodies, thereby improving sensitivity. The optimized FPIA procedure, utilizing the combination of mAb 5B2 and ERM-FITC tracer, demonstrated a minimum IC50 value of 739 g/L for ERM. For ERY detection in milk, the established FPIA was employed, yielding a 1408 g/L limit of detection (LOD). This method demonstrated recovery rates between 9608% and 10777%, and coefficients of variation (CVs) ranging from 341% to 1097%. The developed FPIA's detection time, spanning the period from sample addition to the readout of the result, was under five minutes in duration. The preceding results conclusively established that the proposed FPIA technique, developed in this study, offers a rapid, accurate, and straightforward means of screening ERY in milk samples.

Botulinum neurotoxins (BoNTs), produced by Clostridium botulinum, are the causative agents of foodborne botulism, a rare but potentially fatal type of food poisoning. This review addresses the bacterium, spores, toxins, and botulism, and explores the use of physical treatments (including heating, pressure, irradiation, and emerging technologies) for controlling this biological food hazard. This bacterium's spores are remarkably resistant to harsh environmental conditions, including high temperatures; thus, the 12-log thermal inactivation of *Clostridium botulinum* type A spores remains the standard for commercial food processing procedures. Still, recent progress in non-thermal physical processes provides an alternative to thermal sterilization, yet some limitations remain. The inactivation of BoNTs is contingent upon a low radiation dose of 10 kGy. Despite the immense pressure of 15 GPa, high-pressure processing (HPP) fails to deactivate spores, necessitating a supplementary heat treatment for complete inactivation. Emerging technologies show some potential in combating vegetative cells and spores, but their application in the context of C. botulinum is quite restricted. Different variables relating to bacteria (including their vegetative state, growing conditions, and type), the food matrix (regarding its composition, form, acidity, temperature, and water activity), and the applied treatment method (with aspects like power, energy level, frequency, and distance) all collectively impact the effectiveness of the treatments against *C. botulinum*. Additionally, the unique mechanisms of action exhibited by different physical technologies allow for the integration of diverse physical treatment methods, thus enabling additive and/or synergistic effects. Decision-makers, researchers, and educators will find in this review a structured approach to controlling C. botulinum dangers through the use of physical interventions.

Consumer-oriented rapid profiling methods, including free-choice profiling (FCP) and polarized sensory positioning (PSP), have been the subject of extensive study in recent decades, providing a contrasting viewpoint to conventional descriptive analysis (DA). Water samples were subjected to DA, FCP, and PSP evaluations, using open-ended questions to discern and compare sensory profiles in this investigation. For the purpose of DA assessment, a trained panel of 11 evaluated ten bottled water samples and one filtered water sample; a semi-trained panel of 16 (FCP) and 63 naive consumers (PSP) completed additional evaluations. microbiome data The DA results were scrutinized via principal component analysis, and multiple factor analysis was applied to the FCP and PSP data. The water samples were categorized by their total mineral content, a key factor in determining their heavy mouthfeel characteristics. In terms of overall discriminatory patterns, the samples from FCP and PSP revealed similar trends, yet the DA samples presented a divergent pattern. Sample discrimination, employing confidence ellipses from DA, FCP, and PSP, showed that consumer-oriented methodologies effectively distinguished samples with greater clarity than the DA approach. Rolipram Consumer-oriented profiling techniques were applied throughout this study to analyze sensory profiles and provide insightful data concerning consumer-reported sensory attributes, even for samples with subtle differences.

The interplay between gut microbiota and obesity's pathophysiology is noteworthy. Core-needle biopsy The potential of fungal polysaccharides in combating obesity remains promising, but the intricate mechanisms involved necessitate further research. This experiment investigated the potential mechanism of Sporisorium reilianum (SRP) polysaccharides in alleviating obesity in male Sprague Dawley (SD) rats fed a high-fat diet (HFD), utilizing metagenomics and untargeted metabolomics. An 8-week intervention involving SRP (100, 200, and 400 mg/kg/day) dosage led to an examination of correlated indices related to obesity, gut microbiota, and untargeted metabolomics in the rat models. SRP treatment in rats effectively lowered obesity and serum lipid levels, improving the state of hepatic lipid accumulation and adipocyte hypertrophy, particularly in those treated with a substantial dosage. SRP's effect on rats consuming a high-fat diet involved the modulation of gut microbiota composition and function, and a reduction in the ratio of Firmicutes to Bacteroides at the phylum level. At the genus level, a rise in the presence of Lactobacillus species occurred, accompanied by a decline in the presence of Bacteroides species. Regarding species-level abundance, Lactobacillus crispatus, Lactobacillus helveticus, and Lactobacillus acidophilus proliferated, whereas Lactobacillus reuteri and Staphylococcus xylosus abundances diminished. Gut microbiota's function primarily involves the regulation of lipid and amino acid metabolisms. Untargeted metabolomics analysis revealed a correlation between 36 metabolites and SRP's anti-obesity properties. Finally, the processes of linoleic acid metabolism, phenylalanine, tyrosine, and tryptophan biosynthesis, and the phenylalanine metabolic pathway exhibited a favorable influence on obesity in those who received treatment with SRP. Analysis of study results shows that SRP demonstrably improved metabolic pathways linked to gut microbiota, leading to a reduction in obesity, and thus making SRP a possible tool for both preventing and treating obesity.

For the food sector, the development of functional edible films holds promise, and the improvement of their water barrier properties has remained a significant research area. In this research, an edible composite film containing curcumin (Cur), zein (Z), and shellac (S) was developed, showcasing remarkable water barrier and antioxidant properties. Curcumin's incorporation substantially diminished water vapor permeability (WVP), water solubility (WS), and elongation at break (EB), while simultaneously boosting tensile strength (TS), water contact angle (WCA), and the film's optical properties. Employing SEM, FT-IR, XRD, DSC, and TGA techniques, the ZS-Cur films were examined, revealing hydrogen bond formation between curcumin, zein, and shellac. The microstructure of the film was altered, and thermal stability was enhanced. The curcumin release mechanism within the film matrix showed a controlled release pattern. E. coli exhibited inhibited growth in the presence of ZS-Cur films, which also displayed notable pH responsiveness and strong antioxidant activity. Thus, the insoluble active food packaging created in this study establishes a novel methodology for the development of functional edible films and also presents a viable option for the use of edible films to extend the freshness period of fresh food.

Wheatgrass, a valuable source of nutrients and phytochemicals, possesses therapeutic properties. Although this is the case, its restricted lifespan renders it unavailable for employment. For improved storage and subsequent increased availability, the creation of storage-stable products requires careful and effective processing. The procedure for processing wheatgrass includes a key stage, drying. This study examined the impact of fluidized bed drying on the proximate, antioxidant, and functional characteristics of wheatgrass. Wheatgrass was dried at varying temperatures (50, 55, 60, 65, 70 degrees Celsius) in a fluidized bed drier, with the air velocity consistently set at 1 meter per second. As the temperature increased, the rate of moisture reduction accelerated, and all drying procedures occurred within the falling rate period. Analysis of moisture content in thin-layer drying processes involved the application of eight mathematical models, followed by an evaluation process. The wheatgrass drying kinetics were best explained by the Page model, followed closely by the Logarithmic model. The Page model's R2 values fluctuated between 0.995465 and 0.999292; chi-square values were between 0.0000136 and 0.00002; root mean squared values spanned between 0.0013215 and 0.0015058. An effective moisture diffusivity range of 123-281 x 10⁻¹⁰ m²/s was observed, alongside an activation energy of 3453 kJ/mol. Regardless of the temperature, the proximate composition displayed a consistent profile.
