Application of Nanotechnology to Develop Carrageenan-based Films and Coatings as Carriers for Essential Oils.

This review highlights the effect of combining bioactive agents, especially nanoparticles, in carrageenan coating to increase the quality and stability of foods. This study is designed based on a review of previous studies. Biopolymer coatings and films are suitable for food and non-food packaging due to their degradability, renewable and edible nature. Edible coatings and films are based on polysaccharides, proteins, and lipids. They confer some beneficial effects on foods, such as improvement of appearance and texture, reducing the amount of moisture loss and oxidation, prevention of the release of gases and control of microbial growth, delaying ripening and adverse changes in color and taste, improvement of nutritional value, and increasing the shelf life of the product. These improvements lead to the prevention of food spoilage and increase the shelf life of various foods. In addition, nanomaterials and food additives such as antimicrobial and antioxidant agents, flavorings, and colors can be incorporated into food coatings and films to expand their applications. Nanotechnology can be applied in coatings and food films using nanoparticles. However, more research is still needed to gather information about coating formulations, especially when new materials are incorporated into them.
