Editorial: Sustainable active packaging for food safety and preservation: technological, consumer, and environmental perspectives

Growing concerns about the environmental impact of petroleum-based plastics, along with 25 demand for sustainable solutions that also ensure food safety and quality, have driven 26 the development of biodegradable packaging. These eco-friendly alternatives go beyond the 27 basic role of packaging by including functional agents, such as antioxidants, antimicrobials, 28 ethylene scavengers, or modified atmospheres, that help preserve food quality and extend shelf 29 life. 30To develop such packaging, researchers are investigating a wide range of biopolymers derived 31 from plant, animal, or microbial sources, either individually or in combination. These efforts have 32 led to innovative advances in the field. However, despite the progress, significant challenges 33 remain. A primary concern is replicating the mechanical strength, appearance, and protective 34 qualities of traditional plastics, while maintaining sensory properties. Additional barriers include 35 the difficulty of scaling production and the high cost associated with biopolymer materials. 36To address these issues, several strategies are being explored.
