Food preservation is essential for maintaining safety, nutritional value, and quality while meeting growing global food demands. Traditional techniques like drying, salting, and pasteurization have evolved into advanced methods, including bio-preservation, Nano-encapsulation, and high-pressure processing, offering enhanced shelf life and food safety. These innovations are particularly significant in addressing the challenges of microbial spoilage and maintaining the sensory qualities of food.
The review emphasizes the role of bio-preservatives as natural alternatives to chemical additives, meeting consumer demands for healthier options. Furthermore, nanotechnology has emerged as a game-changing approach, enabling improved food packaging, preservation, and nutrient delivery. These cutting-edge techniques showcase the dynamic evolution of food preservation, aligning with consumer preferences and the need for sustainable practices in the food industry.
