Abstract
This study investigated the use of a natural deep eutectic solvent-based polyphenolic extract (DSE) from date fruit seed as a bioactive and functional component for the development of bioactive carboxyl methylcellulose-poly(vinyl)alcohol (CMCPVA) films. The impacts on the physicochemical, structural, water barrier and bioactive properties of the CMCPVA films were studied. Different concentrations of DSE (1.5%, 2%, 2.5%, and 3%) incorporated into CMCPVA film increased the total phenolic content (0.08 to 0.17 mgGAE/mL), DPPH scavenging activity (4.08 to 5.11 mmol GAE/mL), and ferric ion-reducing antioxidant power (0.82 to 1.46 μmol TE/mL) of the films. The antibacterial activities against S. aureus, L. monocytogenes, S. typhimurium, and E. coli were also improved. In particular, a 4-5 log reduction was recorded for CMCPVA film incorporated with 3% DSE. Also, the presence of DSE enhanced elongation at break (25.53% to 93.23%) and film thickness (0.10 to 0.19 mm), whereas tensile strength (6.39 to 1.40 MPa) and Young's modulus (25.89 to 2.85 MPa) decreased. Furthermore, UV-shielding performance improved, opacity decreased from 2.93 to 0.86, while the water vapor permeability was not significantly affected ranging from 3.01 to 5.83 (X 10-10 g/m.s.Pa). The application of CMCPVA film incorporated with 3% DSE (CMCPVA_3) as a bioactive film for preserving sliced and whole shiitake mushrooms at refrigeration temperature for 8 to 12 days was studied. The CMCPVA_3 film preserved the mushrooms' color, browning degree, and texture compared to the cling film-covered samples. There is potential for the successful application of NADES-based polyphenolic extract in biopolymer films for food preservation.
