The increasing demand for sustainable food packaging has led to significant advancements in edible coatings and films, which offer an eco-friendly alternative to conventional plastic packaging. Edible coatings and films are biodegradable layers derived from natural materials, which serve as protective barriers against moisture, oxygen, and microbial contamination, effectively extending the shelf life of various food products. Beyond their role in preservation, edible coatings can be enriched with essential nutrients, bioactive compounds, and functional ingredients to enhance the nutritional value and health benefits of foods. This chapter explores the composition, mechanisms of nutrient incorporation, and structural properties of edible coatings; factors affecting the coating; and case studies emphasizing their role in food quality enhancement and nutrient stability. Additionally, it examines the impact of nutrients on the effectiveness of these coatings in food preservation, as well as consumer acceptance factors. Through a combination of scientific research and practical applications, this chapter provides valuable insights into the potential of nutrient-enriched edible coatings in addressing global nutritional challenges while promoting sustainability in food packaging.
