Abstract

Use of nanocomposites is a well-established approach in enhancing the mechanical 52 and barrier properties of bionanocomposite film for food packaging applications. The 53 seed mucilage of Ocimum basilicum was employed for the preparation of 54 bionanocomposite films with montmorillonite (MMT) as nanofiller. The films were 55 prepared by solvent-casting method at varied solution pH (1, 3, 5 and 9) and MMT 56 loading (1%, 3%, 5%, 10%, 15% and 20%). The films were characterized for physical, 57 mechanical and barrier properties in addition to microstructure and X-ray diffraction 58 pattern. XRD analysis revealed the exfoliated dispersion of MMT at pH 9, confirming its 59 effective interaction with the bionanocomposite film. Maximum film tensile strength was 60 achieved at a lower MMT load of 5%. Water vapour permeability reduced with increase 61 in MMT loading up to 5%, followed by an increase at higher MMT loadings. Film formed 62 at pH 9 showed tensile strength of 17.3 ± 0.33 MPa and reduced water vapour 63 permeability (WVP) of 0.21g.mm.m-2 .hr-1.kPa-1.
