dc.description.abstract | The concerns about food safety and plastic pollution encourage the development of food packaging that is antimicrobial and biodegradable. In this study, food packaging films were prepared by blending poly(ε-caprolactone) (PCL) with chitosan (CHT) and grapefruit seed extract (GFSE) using melt blending followed by compression molding. CHT was used as a carrier for GFSE and different GFSE/CHT ratios (0.5, 1.0, 1.5, 2.0 and 2.5 mL/g) affected the films’ morphology, mechanical and antimicrobial properties. GFSE-loaded films were effective against food-borne pathogen Escherichia coli and could inhibit the bacterial growth for 120 h when GFSE content reached 0.5 mL/g. Food packaging test showed that PCL/CHT/GFSE films were effective to inhibit the growth of E. coli on salmon during storage, and no mold growth was observed on the bread packaged with films containing ≥ 1.0 mL/g GFSE after 7 days. Furthermore, the biodegradability of PCL, PCL/CHT and PCL/CHT/GFSE films in seawater was investigated. | |
