AB  - BACKGROUND: Biodegradable films from basil seed mucilage (BSM) were formed and 
      modified with several di-carboxylic acid crosslinkers; i.e. tartaric acid (TA), 
      malic acid (MA) and succinic acid (SA) with varying acidity and chemical 
      structures, to enhance mechanical properties and water barrier ability. Basil 
      seeds have a reasonable mucilage content and valuable properties; thus, it has 
      the potential to develop valuable new biodegradable films. RESULT: We 
      characterized BSM films with the three crosslinkers using Fourier-transform 
      infrared (FTIR) spectra and observed a 1730 cm(-1) CO stretching peak, which 
      confirmed ester linkage between the mucilage and crosslinkers. The crosslinked 
      films showed higher gel fraction than native films. The crosslinked films showed 
      better swelling and water vapor permeability with SA than with TA and MA. 
      Crosslinking led to significant improvement in strain at maximum load. Further, 
      the stress maximum load was comparable to that of commercial low-density 
      polyethylene (LDPE) film. Crosslinked films showed additional homogeneous 
      morphology and an increase in thermal degradation temperatures. CONCLUSION: 
      Crosslinking with dicarboxylic acids improved all the key properties of BSM 
      films, including excellent stress and strain at maximum load, improved barrier 
      capability and thermal properties. Thus, these films showed good potential as 
      biodegradable films, especially for food packaging. (c) 2019 Society of Chemical
