Abstract

In this study, smart films of EFS, EFS-SiO₂ and EFS-SiO₂-CRE were successfully developed by using Euryale ferox starch (EFS), nano-SiO₂ and Chinese rose extract (CRE). The Chinese rose flower had a high content of anthocyanins (1.73 mg/g) and CRE exhibited different colors in varying pH buffers (2-13). The addition of nano-SiO₂ decreased tensile strength (TS) (41.08 to 16.75 MPa) and elongation at break (EAB) (6.71 to 2.69 %) of the EFS film. Incorporation with CRE could significantly increase water vapor permeability (4.47 to 5.35 10^-11 g m^-1 s^-1 Pa^-1), TS (16.75 to 26.19 MPa) and EAB (2.69 to 4.62 %) of the EFS-SiO₂ film. Incorporation of Nano-SiO₂ and CRE significantly enhanced the thermal stability and light barrier performance of the EFS film. The EFS-SiO₂-CRE films showed excellent pH and ammonia sensitivities with different colors varying from red to blue. The EFS-SiO₂-CRE-III film displayed strong antioxidant activity with a maximum DPPH scavenging rate of 96.54 ± 0.44 %. When employed for monitoring freshness of chicken breast meat, the EFS-SiO₂-CRE-III film showed the most significant visible color changes at 24 h when the TVB-N content was 21.7 mg/100 g. Findings supported the application of this strategy in fabrication of the EFS-SiO₂-CRE-III film for smart packaging.
