Edible Packaging and Coating Systems for Enhancing the Shelf Life of Nuts
摘要
Edible packaging and coating technologies have emerged as promising and sustainable alternatives to conventional plastic-based packaging and traditional preservation techniques in the food industry. They are particularly effective at extending the shelf life of foods such as edible nuts. These biodegradable and sustainable packaging solutions not only reduce environmental pollution but also help maintain food quality by minimizing oxygen exposure, delaying moisture absorption, and preventing lipid oxidation and microbial contamination. Natural biopolymers, including proteins, polysaccharides, and lipids, have been extensively studied for their potential applications in edible coatings and films, offering a range of functionalities while enhancing barrier properties and improving food safety. Recent advancements in edible coatings have further improved food preservation capabilities by incorporating natural oils and bioactive compounds with antimicrobial and antioxidant properties. Although edible packaging presents an eco-friendly and effective method for preserving nuts, challenges remain regarding mechanical strength, stability under various environmental conditions, and large-scale commercialization. By addressing these challenges, edible packaging could transform food preservation strategies, reduce reliance on synthetic packaging, and contribute to a more sustainable food industry.
