Overview

Randomized trial evaluates biodegradable starch films with citrus essential oils for food preservation, indicating sustainable packaging options.

Key Points

  • The aim is to develop and evaluate biodegradable starch films infused with citrus essential oils for sustainable food preservation.
  • Developed starch-based films with citrus peel essential oils (0.5% to 2%) and analyzed their properties.
  • Conducted structural and thermal characterization using XRD, SEM, FTIR, and TGA/DTG for selected formulations.
  • Evaluated antimicrobial properties, soil biodegradation, and phytotoxicity assays of final products.
  • Films with lemon and tangerine essential oils showed significant antimicrobial activity against foodborne pathogens.
  • Soil biodegradation reached over 50% mass loss within 15 days, indicating high biodegradability.
  • Phytotoxicity tests confirmed the environmental safety of degraded residues.
