Overview

Randomized trial demonstrates improved antioxidant activity in lignin nanoparticles, suggesting a new approach for lignin valorization.

Key Points

  • This research aims to develop a biochemo-catalytic method to synthesize lignin nanoparticles with antioxidant properties from alkali black liquor derived from oil palm trunk.
  • Conducted biochemo-catalytic synthesis at 60 °C and pH 4.5 in two stages
  • Evaluated laccase effects with dosages of 10 to 1000 POU/mg for 30 to 90 min
  • Combined optimal laccase conditions with deep eutectic solvents (LBDES and LCDES)
  • LBDES + laccase LNPs achieved antioxidant activities of ABTS 3223.73 mg TE/g, DPPH 2300.94 mg TE/g, TPC 921.61 mg GAE/g, exceeding LCDES + laccase by 27–108%
  • Mean size of resulting LNPs was 150.7 ± 48.7 nm with a ζ-potential of −35.4 mV
  • Highest stability recorded with LCDES + laccase LNPs, onset temperature of 301 °C, and mean residue at 800 °C was 32.9 wt %
