Edible Packaging: A Technological Update for the Sustainable Future of the Food Industry

Abstract

This review aims to address the current data on edible packaging systems used in food production. The growing global population, changes in the climate and dietary patterns, and the increasing need for environmental protection, have created an increasing demand for waste-free food production. The need for durable and sustainable packaging materials has become significant in order to avoid food waste and environmental pollution. Edible packaging has emerged as a promising solution to extend the shelf life of food products and reduce dependence on petroleum-based resources. This review analyzes the history, production methods, barrier properties, types, and additives of edible packaging systems. The review highlights the advantages and importance of edible packaging materials and describes how they can improve sustainability measures. The market value of edible packaging materials is expanding. Further research on and developments in edible food packaging materials are needed to increase sustainable, eco-friendly packaging practices that are significant for environmental protection and food safety.

From Fields to Films: Exploring Starch from Agriculture Raw Materials for Biopolymers in Sustainable Food Packaging

“…Injection molding is suitable for high-volume production of intricate parts with tight tolerances and can be used in conjunction with the extrusion method. Additionally, compression molding is commonly used due to its low energy requirement and rapid formation [48]. In the dry process, the twin-screw extruder emerges as the most commonly utilized type of extrusion for starch-based plastics.…”

Analysis of Bioactive Aroma Compounds in Essential Oils from Algerian Plants: Implications for Potential Antioxidant Applications

“…Therefore, there has been increasing interest in their use as natural antioxidants and their addition to foods. They have also been incorporated into active packaging and edible coatings to extend the shelf life of foods [ 12 , 13 , 14 , 15 , 16 ].…”

Alginate Films Enriched in Raspberry and/or Black Currant Seed Oils as Active Food Packaging

“…One of the solutions is the production of edible films and coatings. Such packaging is intended to protect perishable food, thus reducing food waste and minimizing waste from packaging [1][2][3][4].…”

“…Moreover, adding suitable active compounds to the packaging can result in obtaining a film with antioxidant and antibacterial properties being obtained, prolonging the shelf life of packed food. One can also monitor food quality by producing intelligent films sensitive to pH, temperature, or color changes [3,[6][7][8].…”
