Mechanical, physical, water vapor barrier, and functional properties of carboxymethyl cellulose/anthocyanin/TiO2 films for real-time food quality monitoring

Résumé

To enhance the properties of functional film containing carboxymethyl cellulose (CMC) and Carissa carandas L. fruit and Clitoria ternatea flower anthocyanins (CCA) while maintaining functional properties for quality monitoring, titanium dioxide nanoparticles (nano-TiO2) were added at different concentrations. Nano-TiO2 addition affected the films’ color by increasing b* and decreasing L* and a* values as well as lowering light transmittance and transparency. Increasing the nano-TiO2 content improved the tensile strength (17.70–31.33 MPa) but decreased the elongation at break (50.23–40.03 %) and degree of swelling (149.55–92.02 %) of the CMC/CCA film (p < 0.05). Nano-TiO2 addition also significantly improved the water vapor barrier properties of films (3.88–3.42 × 10−10 g m−2 s−1 Pa−1). After exposure to volatile ammonia, the nano-TiO2-added films showed poor color changes, particularly at high nano-TiO2 levels. Fourier transform infrared analysis revealed that there were no major changes in the polymer structure. X-ray diffraction analysis confirmed the presence of nano-TiO2 in the CMC/CCA functional films. Confirming our hypothesis, the 1 % nano-TiO2-loaded CMC/CCA functional film exhibited optimal performance between enhanced properties and color indication capability, making it efficient for real-time quality change detection. Therefore, the developed nano-TiO2-loaded CMC/CCA functional film shows promise as an intelligent food packaging.
