Overview

Randomized trial evaluates enzymatic extraction of chitin in insect byproducts, highlighting sustainable biopolymer recovery.

Key Points

  • The aim is to optimize enzyme-assisted extraction of chitin and chitosan from Tenebrio molitor processing residues.
  • Optimization of extraction parameters using Face-Centered Central Composite Design, assessing pH, enzyme concentration, and extraction time.
  • Comparison of enzymatic deproteinization with conventional chemical methods through proximate analysis and efficiency evaluations.
  • Characterization of extracted compounds using ATR-FTIR, SEM, and TGA for structural and performance assessment.
  • Achieved deproteinization efficiencies of 86.1% to 94.1%, nearing chemical method performance.
  • Extracted chitosan demonstrated a water-binding capacity of 773% ± 19 and a fat-binding capacity of 715% ± 12.
  • Degree of deacetylation of isolated chitosan was 85%, similar to commercial standards.
