Conclusion
The active nanocomposite films based on FPI/FSG blend incorporated with BEO and ZnONP were developed. The developed films showed the improved mechanical and water vapour barrier properties as well as thermal stability, compared with control films (without BEO and ZnONP). Moreover, FPI/FSG films incorporated with BEO greatly inhibited the growth of Gram-positive and Gram-negative foodborne pathogenic and spoilage bacteria. Antimicrobial activities of BEO incorporated FPI/FSG films were more pronounced in the presence of ZnONP. Thus, FPI/FSG films incorporated with BEO and ZnONP could be used as an active food packaging to prevent growth of pathogen and spoilage bacteria in food.
