BIOACTIVE FOOD PACKAGING: SYNBIOTIC EDIBLE FILM AND COATINGS
Consumer awareness of the impact of synthetic food packaging on the environment and human health has forced the food industry to look for more sustainable alternatives, such as natural biopolymers, to replace traditional packaging materials. In this context, edible films and coatings have come to the forefront in recent years due to their low cost, biodegradability and environmental friendliness. The ability to transform these films and coatings into bioactive packaging with the addition of components such as antimicrobial and antioxidant compounds, probiotics and prebiotics shows promising results in terms of consumer health and food safety. Probiotics are live microorganisms that provide health benefits to the host when administered in sufficient quantities. Many stress factor in food production, transportation and storage limit the viability of probiotic microorganisms. Rather than adding probiotics directly to food, a promising alternative approach is to incorporate them into edible films and coatings to control foodborne microorganisms, improve food safety and provide health benefits. Synbiotic edible films are produced by simultaneous application of probiotic microorganisms and prebiotics such as oligosaccharides, inulin, dextrin to the biopolymer matrix to ensure adequate probiotic uptake by the host. With this application, both the viability of the probiotic strains in the film or coating is maintained and the characteristic properties of the films can be improved with prebiotics. In this study, recent research on synbiotic edible films and coatings, the effect of probiotics and prebiotics on the physical, chemical and mechanical properties of films/coatings, and the viability of probiotic microorganisms in synbiotic films and coatings were reviewed.
