Abstract

As the world population increases, supply and quality of fresh foods becomes a challenge. The development of food packaging films and coatings is one of the modern strategies for preserving food products and ensuring their freshness and quality during storage. Exopolysaccharides (EPSs), usually derived from Lactic Acid Bacteria (LAB), are molecules that are released by most bacteria which act as a protection for the bacteria. In this investigation, a dissolved EPS, combined with a plasticizer, was employed in the formulation of an edible film. The findings revealed that fruits coated with lyophilized EPS exhibited superior resilience against environmental factors that contribute to spoilage. The utilization of microbial exopolysaccharides emerges as a promising and sustainable alternative to contemporary food packaging techniques. This study underscores the potential of this approach to enhance the shelf life and quality of food products, thereby addressing the pressing challenges associated with the growing global population.
