Abstract

Tomato (Solanum lycopersicum L.) is a climacteric horticultural commodity that is highly susceptible to postharvest quality deterioration due to high respiration and transpiration rates. This study aimed to evaluate the effects of breadfruit (Artocarpus altilis) starch concentration as an edible coating material and storage duration at 25 °C on the physical and chemical quality of tomato fruit. The study used a completely randomized design (CRD) with a combination of breadfruit starch concentrations of 0%, 1%, 2%, 3%, 4%, 5%, and 6%, and storage durations of 0, 2, 4, 6, 8, and 10 days. The observed parameters included vitamin C content, weight loss, total soluble solids, texture, and pH. The results showed that breadfruit starch concentration and storage duration significantly affected vitamin C content, weight loss, and total soluble solids, but had no significant effect on texture and pH. The best treatment was obtained at a breadfruit starch concentration of 6%, which maintained the highest vitamin C content, minimized weight loss, and resulted in a lower final total soluble solids value compared with the other treatments. Breadfruit starch-based edible coating has the potential to be used as an environmentally friendly postharvest technology to maintain quality and extend the shelf life of tomato fruit.

Abstract

Fungal postbiotics have gained increasing attention as a source of bioactive metabolites with potential applications in food preservation. Previous studies have demonstrated that candidate fungal postbiotics produced by Rhizopus oligosporus cultivated on edamame husks (Glycine max L. Merrill) contain phenolic compounds and exhibit antioxidant activity. Building on these findings, this study aimed to characterize the metabolites present in candidate postbiotics and evaluate their antibacterial potential using molecular docking. Candidate postbiotics were produced by submerged fermentation and analyzed using gas chromatography-mass spectrometry (GC-MS). The major metabolites were docked to Staphylococcus aureus DNA gyrase subunit B (PDB ID: 4URM). GC-MS revealed a diverse metabolite profile dominated by 2,3-butanediol, followed by glycerin, dianhydromannitol, benzoic acid, and n-hexadecanoic acid. All selected metabolites exhibited negative predicted docking score, indicating thermodynamically favorable interactions with the target protein. Among them, n-hexadecanoic acid showed the strongest predicted binding affinity, followed by benzoic acid. These findings suggest that candidate fungal postbiotics derived from R. oligosporus-fermented edamame husks are promising natural bioactive ingredients for food biopreservation and active food packaging. Future molecular dynamics simulations and experimental validation are needed to confirm these computational predictions.

Abstract

Recent advances in nanobiotechnology have promoted the development of fungal-mediated nanoparticle synthesis as a sustainable alternative to conventional physical and chemical methods. This narrative review provides a comprehensive overview of fungi as biofactories for the synthesis of mycogenic nanoparticles, with emphasis on synthesis components, production conditions, and multi-sectoral application. A literature search was conducted using scientific databases to identify original open-access articles published between 2021 and 2026. After applying predefined inclusion and exclusion criteria, 30 studies were selected for qualitative analysis. Fungi provide an efficient platform for nanoparticle production because they secrete extracellular enzymes, proteins, polysaccharides, and secondary metabolites that function as natural reducing, capping, and stabilizing agents. The physicochemical properties of mycogenic nanoparticles are influenced by reaction parameters such as pH, temperature, precursor concentration, and cultivation conditions. The incorporation of natural biopolymers, including chitosan and carboxymethylcellulose, further improves nanoparticle stability and biological activity. Mycogenic nanoparticles have demonstrated broad potential in agriculture, food systems, environmental, and biomedicine through their antimicrobial, antifungal, antioxidant, anticancer, biofungicidal, wastewater treatment, and active food packaging application. However, several challenges remain, including limited knowledge of fungal synthesis mechanisms, large-scale production, and nanoparticle stability and biosafety. Future research should improve the understanding of fungal metabolism, optimize fermentation process, standardize synthesis methods, and evaluate safety through in vivo studies.
