Assessment of the performance of several novel approaches to improve physical properties of guar gum based biopolymer films

• Orange peel oil/HNT addition or crosslinking improved physical properties of films. Samples studied had distinctly different solubilities and visual appearances. oil HNT increased film hydrophobicity. All films other than control displayed antimicrobial activity. Biopolymer-based are natural, renewable, nontoxic biodegradable alternatives to plastic packaging. Despite years ongoing research, biopolymer still lag much behind in mechanical barrier properties. In this study, guar gum (GG) based were prepared evaluate the potential some novel applications enhancing For purpose, GG glycerol with varying amounts orange (1%, 2% v/v), and/or reinforced halloysite nanotubes (HNT), crosslinked sodium trimetaphosphate (STMP). Oil incorporation, despite weakening films’ strength, hydrophobicity enhanced its water Crosslinking, decreased relatively high solubility while also improving preserved activity stabilized provided controlled release volatile essential oil. Findings indicated possibility methods employed.
