What is it about?
Oil-incorporated gelatin-based films displayed antioxidant, bacteriostatic properties, and pH responsivity during cheese storage compared to control groups. This trial revealed a significant growth decrease of Salmonella spp., P. aeruginosa, and E. coli, over 14-day storage at 5 °C, indicating the minimized microbial cheese spoilage during storage and the promising application of films for food-active packaging.

Why is it important?
The oil influenced the film's physicochemical properties, decreasing the water vapor permeability. Furthermore, the oil added to the film conferred antioxidant and antimicrobial activities, due to the phenolic composition. The storage of cheese samples packed with this active film revealed a significant decrease in the growth of food-borne pathogens.
Perspectives
The observed antioxidant and antimicrobial effects allow making a preliminary inference that the buriti oil-gelatin-based film is promising to develop active biodegradable packaging to extend the shelf life of food products.
