Abstract

The invention relates to a method for the production of chitin and/or chitosan from insects. More specifically, the invention relates to a method for the production of chitin and/or chitosan from insect cuticles, comprising an insect cuticle pressing step, followed by a step involving the enzymatic hydrolysis of the insect cuticles using a proteolytic enzyme, the cuticles having been treated with an oxidising agent prior to the enzymatic hydrolysis.
