Abstract

Pupae shell of Black Soldier Fly (BSF) potentially serve as a green and new alternative source of chitosan. Deacetylation by using H2O2 is the most important step for the quality characteristic of chitosan. The objective of this study was to determine the effect of hydrogen peroxide concentration on the deacetylation degree of chitosan extracted from maggot waste. Different hydrogen peroxide concentration (0%, 13%, 15%, and 20%) was studied. The degree of deacetylation of chitosan, determined using FTIR, was found to be 75.3%, 77.6%, 78%, and 78.6% for H2O2 concentrations of 0%, 13%, 15%, and 20%, respectively. The quality of chitosan extracted from the pupae shell of maggot waste meets the requirements of SNI 7949-2013. Higher H2O2 concentrations increased the deacetylation degree of chitosan extracted from maggot waste
