Summary: In this study, a dominant pathogenic fungus of fresh walnuts was identified as Penicillium crustosum, which has a high water content and is susceptible to decay. The antifungal effect of herbal smoke fumigation using six different herbs was tested and results showed that smoke from all six herbs successfully inhibited P. crustosum growth. A. argyi smoke had the best antifungal effect, containing higher contents of phenol, eugenol, and other antimicrobial components. Fumigation with A. argyi smoke in a real storage situation effectively controlled fungal contamination and maintained the quality of fresh walnuts.

Summary: Fresh-cut fruits are prone to spoilage and bacterial contamination. Edible coating films containing nanoemulsions of polysaccharides loaded with essential oils have the potential to extend the shelf life and enhance the quality of fruits. This study aimed to optimize the production of citral and citronella oil nanoemulsions and incorporate them into a natural antimicrobial coating for fresh-cut apples. The results showed that stable nanoemulsions with droplet sizes less than 500 nm were successfully achieved and maintained stability for 3 weeks at 4℃. The relationship between droplet size and antibacterial activity was observed, with smaller droplet sizes (< 100 nm) exhibiting higher efficacy against Listeria monocytogenes and Escherichia coli. These findings highlight the importance of droplet size in the effectiveness of the nanoemulsions as an antibacterial coating for fresh-cut fruits.

Summary: The effects of hydrogen sulfide (H2S) on browning and quality maintenance of fresh-cut peach fruit were investigated. H2S treatment inhibited surface browning, reduced respiration rate and weight loss, and delayed firmness decline during storage, while soluble solids content (SSC) and microbial growth remained unaffected. H2S treatment also preserved higher levels of phenolic compounds, such as neo-chlorogenic acid, catechin, and quercetin, and slowed down their degradation by increasing the activities of phenolic biosynthesis-related enzymes and suppressing the oxidative activities of polyphenol oxidase (PPO). Additionally, H2S stimulated the accumulation of amino acids and their derivatives, including proline, gamma-aminobutyric acid (GABA), and polyamines (PAs), by enhancing biosynthesis and inhibiting degradation. These findings suggest that H2S treatment enhances the accumulation of phenolic and amino acid compounds, leading to improved antioxidant activity and membrane integrity, ultimately inhibiting browning development and maintaining fruit quality. The study highlights the potential of using H2S as a promising approach for browning inhibition and quality maintenance in fresh-cut peach fruit.

Summary: This study evaluated the effects of ethanol treatment on phenolic and reactive oxygen species metabolism, as well as microbial diversity in fresh-cut lotus roots. The results showed that ethanol treatment suppressed the activity and gene expression of certain enzymes, leading to decreased accumulation of phenols and soluble quinones. Ethanol treatment also resulted in changes in the levels of individual phenols and improved antioxidant activity. Furthermore, the study found that ethanol treatment inhibited the abundance of certain microbial species. These findings suggest that ethanol treatment is a potential technology for preserving the quality and antioxidant ability of fresh-cut products.

Summary: In this study, it was found that cold plasma treatment effectively preserved the quality of blueberries and inhibited the growth of microorganisms. The treatment also increased the levels of phenols, flavonoids, and anthocyanins, indicating an impact on phenolic metabolism. The study further identified 59 substances in blueberries treated with cold plasma, and the activities of key enzymes involved in the phenolic metabolism were found to be higher. These results suggest that cold plasma treatment affects the conversion of L-phenylalanine to phenols, flavonoids, and anthocyanins.

Summary: This study aimed to compare the discrimination ability and detection limit of visible and short-wave near-infrared hyperspectral imaging features and spectral information on early implicit bruised pears. Physical characteristics were more sensitive than chemical parameters for bruised pears during postharvest storage. The changes in spectral variations at specific wavelengths could explain the bruising changes in pears. Discrimination models based on selected spectral variables could effectively identify bruised pear areas, and the combination of imaging features and spectral variables achieved higher discrimination rates.

Summary: This study found that H2S treatment can delay the senescence process of postharvest pakchoi by regulating antioxidant system, endogenous H2S and NO metabolism. H2S increased the activities of antioxidant enzymes by up-regulating the expression of enzyme genes, reducing the accumulation of harmful substances. Furthermore, H2S increased the content of cysteine and nitrate in pakchoi by regulating the expression of related genes and enzyme activities, thus slowing down the senescence of pakchoi.
