Investigations on the antioxidant and UV-blocking properties of biodegradable chitosan films enriched with MgO nanoparticles and red dragon fruit peel extract
The aim of the study is to investigate the synergistic impact of MgO nanoparticles and red dragon fruit peel extract (RFE) on chitosan (CS) biofilm. The CS films were analyzed using FTIR, TGA, ESEM/EDX, XRD, UV-spectra analysis along with contact angle measurement, antioxidant activity, overall migration and biodegradation study. The results showed that as the concentration of RFE increases, improvement in UV-blocking and thermal properties is observed. The FTIR analysis revealed the hydrogen bond interactions among CS, MgO nanoparticles, and RFE. The findings showed that a significant (P < 0.05) increase in 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical scavenging activity, reaching to 37.63 % and 62.83 %, respectively. Also, increase in moisture content, water solubility, and water vapor permeability up to 25.64 %, 38.58 %, and 2.83 × 10−10 g m−1 Pa−1 s−1, respectively, was found. ESEM images depicted the aggregation of MgO nanoparticles. The films comply with EU 10/2011 safety standards for fatty foods.
