Zein/eugenol electrospun mats on gelatin/laponite substrate for developing bilayer functional food packaging
AI summary Read the abstract
Researchers developed a bilayer food packaging material by electrospinning zein-eugenol antimicrobial fibers directly onto a gelatin-laponite barrier film, creating a plastic-free composite that extends pork shelf life and avoids the microplastic pollution associated with conventional petroleum-based packaging.
Petroleum-based food packaging causes substantial environmental damage through waste accumulation and microplastic pollution. Therefore, replacing it with biodegradable polymers to extend the shelf life of food products is highly desirable. In this work, a bilayer functional composite with barrier properties and antimicrobial activity was developed for pork preservation. The outer barrier layer of gelatin/laponite (Ge/La) was fabricated by the casting method, while the inner antimicrobial layer of zein/eugenol (ZN/Eu) was prepared through direct electrospinning on Ge/La. The incorporation of La enhanced the thermal stability, mechanical strength, and moisture barrier of the outer layer, while the encapsulation of Eu endowed the inner layer with excellent antioxidant and antimicrobial activities. Furthermore, the Eu release from ZN/Eu fibers was found to follow Fickian diffusion. The bilayer composite of Ge/La@ZN/Eu can prolong pork shelf life by 1 d at 25 °C, demonstrating its great potential in active food packaging.

An Antibacterial and Antioxidant Food Packaging Film Based on Amphiphilic Polypeptides‐Resveratrol‐Chitosan
AI summary Read the abstract
Researchers developed a biodegradable food packaging film made from natural materials including chitosan and resveratrol that kills bacteria and prevents food spoilage. Unlike conventional plastic packaging that breaks down into microplastics, this film is made entirely from biological materials and poses no microplastic contamination risk. This type of eco-friendly alternative could help reduce the microplastics that enter the food supply through traditional plastic packaging.
