Scalable eco-friendly antibacterial paper via stabilized essential oils composites for food preservation.
AI summary Read the abstract
Researchers developed a scalable antibacterial paper coating by stabilizing essential oil composites for roll-to-roll manufacturing, achieving >99.9% inhibition against common pathogens and extending strawberry shelf life by about 7 days while reducing global warming potential by 40% compared to conventional plastic packaging.
Conventional plastic-based food packaging is non-biodegradable and often provides only passive barriers, whereas volatile natural antimicrobials commonly show rapid loss and poor stability during storage. Here, a scalable antibacterial paper was fabricated by integrating a multicomponent steady-state Essential oils (EOs) composite into a conventional coating process compatible with roll-to-roll production. The coated paper achieved >99.9% inhibition against Escherichia coli, Staphylococcus aureus, and Aspergillus niger. In strawberry preservation tests (23 °C, 50% relative humidity), the stabilized composite reduced volatile depletion and extended shelf life by approximately 7 days compared with the control paper. The material maintained packaging-relevant mechanical strength and thermal stability, and the paper substrate remained fully biodegradable. Life cycle assessment further indicated a 40% reduction in global warming potential relative to traditional plastic packaging. This study provides an industry-compatible route to cellulose-based active packaging for reducing food waste and plastic pollution.

Synergistic effects of anthocyanins and essential oils in biopolymer based active and intelligent food packaging for sustainable applications
AI summary Read the abstract
Scientists are developing smart food packaging made from plant-based materials instead of plastic, combining natural pigments (from fruits and veggies) with essential oils to keep food fresher longer while also changing color to warn you if food has spoiled. This review paper summarizes existing research showing these plant-based films fight bacteria and spoilage better when the two ingredients are combined, offering a promising eco-friendly alternative to plastic packaging that could reduce both food waste and plastic pollution.
