Special Issue Information

Dear Colleagues,

Food-borne diseases still represent a widespread health and economic problem, but even these illnesses are preventable. Interventions in food production, processing, and storage can help prevent food from becoming contaminated with bacteria. In this context, the development of emerging technologies, such as active and intelligent, eco-friendly, and efficient antimicrobial packaging has been accelerated significantly to extend the shelf life of foods. The latest research on antimicrobial active packaging materials has focused on combinations of substrates based on renewable and biodegradable polysaccharides augmented by natural antimicrobial agents (essential oils, plant extracts, chitosan, proteins, bacteriocins, and probiotics). Furthermore, the rapid identification of pathogenic and deteriorating bacteria on surfaces and materials used for food production becomes even more fundamental as a preventive strategy to accompany active antimicrobial packaging. These detection systems must be easy to use, portable, and economical. This Special Issue welcomes original research and reviews covering, but not limited to, the use of active packaging and new techniques for controlling and improving the microbiological quality of foods.

Wax apple (Syzygium samarangense) is highly perishable postharvest. Even under refrigerated storage conditions, its shelf life typically lasts only about one week. This study developed a novel antibacterial food packaging membrane to extend its shelf life and explored the underlying preservation mechanisms. A composite fiber membrane was fabricated via solution blow spinning (SBS) using polyethylene oxide (PEO) and oxidized sesbania gum (OSG) incorporated with ε-polylysine (ε-PL). The composite membrane demonstrated exceptional antibacterial activity against both E. coli and S. aureus by disrupting cell wall and membrane integrity, as evidenced by increased protein leakage, alkaline phosphatase activity, and electrical conductivity. Morphological observations through scanning electron microscopy confirmed extensive cellular damage and bactericidal effects. During nine days of ambient storage, the PEO/OSG/PL membrane significantly maintained the postharvest quality of wax apples. This was evidenced by a lower decay index (2.22 ± 0.19) and weight loss rate (5.32 ± 0.16%) compared to the control group, alongside better preservation of firmness (4.11 ± 0.08 N) and color stability. The treatment suppressed respiratory rate and delayed the degradation of soluble solids and titratable acidity. Furthermore, it enhanced antioxidant capacity through higher peroxidase activity and reduced malondialdehyde accumulation, indicating attenuated oxidative stress. Non-targeted metabolomics analysis revealed that the membrane treatment modulated critical metabolic pathways, particularly phenylalanine metabolism and linoleic acid metabolism. These metabolic adjustments contributed to enhanced defense responses and delayed senescence. The results show that the PEO/OSG/ε-PL fiber membrane acts as an effective active packaging material by inhibiting microbial growth and regulating metabolism. This provides a potential method to extend the shelf life of perishable fruits. Full article
