Pectin-based edible films and coatings: From extraction to application on food packaging towards circular economy- A review

Abstract

Pectin-based edible films and coatings have witnessed significant application in fresh food and processed food due to their functionalities as a carrier for active compounds and as a barrier against moisture and gases, which can help maintain the freshness and prolong the shelf-life of food products without sacrificing the sensory acceptance of food products. The current review covers the source and extraction methods of pectin, the use of plasticizers and active agents, the fabrication methods employed, and the application of these films and coating on food products. Thus, using pectin-based edible films and coatings in the food industry is important because it reduces agricultural waste and utilizes by-products of the food processing industry, thereby stimulating sustainable food packaging towards a circular economy.
