Abstract
Peptide-based hydrogels (PHs) are versatile materials with considerable potential in food technology. Advances in synthesis techniques, such as self-assembly, click chemistry, enzymatic cross-linking, and co-assembly with polymers, have improved their production efficiency and scalability. Derived from natural amino acids, PHs are biocompatible, biodegradable, and responsive to environmental factors like pH and temperature. In food technology, encapsulation and controlled release of bioactive compounds enhance nutrient stability, flavor preservation, and bioavailability. PHs serve as texture modifiers, improve product consistency, and possess antimicrobial properties for food preservation by inhibiting spoilage and pathogens. Their biodegradability supports eco-friendly practices and sustainable packaging, including edible films and coatings that extend shelf life. Adjustable properties such as ionic strength make PHs adaptable to specific needs. PHs also show potential in developing advanced food equipment, including 3D printers and encapsulation systems, promoting efficiency and sustainability. This review emphasizes that PHs offer innovative, sustainable solutions to enhance food functionality, quality, and safety, with broad applications in food processing and preservation.
