Summary

Presentation Title: Development of Sustainable Active Packaging Materials from Food Industry Waste

Development of sustainable packaging materials from food processing waste is crucial for circular economy. Bio-based films were developed from pomegranate and orange peel powders. The developed films were characterized for mechanical, antimicrobial/antioxidant, morphological and thermal properties. Results showed that the reduced particle size of powder significantly improved the mechanical properties. Pomegranate and orange peel based films showed very high antimicrobial activity against E. coli and S. aureus. The pomegranate and orange peel based films had homogeneous, smooth, and crack-free surfaces, showing very similar thermal properties. Pomegranate and orange peels could be a good potential as antioxidant and antimicrobial biopolymer sources for sustainable and active food coating/packaging.
