Abstract

The shift towards the use of environmentally friendly biomaterials within the circular economy model has led to increased scientific exploration of cellulose, which is a polymer that is renewable, biodegradable, and widely available in nature. The present work involved the green chemical isolation of nanocellulose (NC) from the corn husk. Then, to produce a quinic acid-modified nanocellulose (Q-NC), the isolated NC was esterified with quinic acid (QA), a naturally occurring bioactive compound. Changes in the structure and the chemical aspects of the material were verified by Fourier-transform infrared spectroscopy (FTIR), solid-state 13C nuclear magnetic resonance (13C NMR), and X-ray diffraction (XRD), while the upgrade in the thermal resistance of Q-NC was evidenced by thermogravimetric analysis (TGA). Antibacterial tests showed that the Q-NC was very effective in inhibiting bacterial growth. Moreover, molecular docking simulation unveiled that Q-NC had strong interactions with the epidermal growth factor receptor (EGFR) kinase domain (PDB IDs: 4WkQ and 2ITY), with the respective binding energies of –12.8 and –11.3 kcal/mol. Besides that, the cheese wrap with PVA/Q-NC films subjected to accelerated storage studies inhibited bacterial spoilage completely up to fifteen days and thus has the potential for food packaging applications. In brief, Q-NC is a potential eco-friendly biomaterial that can be used for both food preservation and wound healing.
