The invention relates to chitin, a hydrolysate and a method for the production of at least one desired product from insects. More specifically, the invention relates to a method for the production of chitin and/or chitosan from insect cuticles, comprising a step in which insect cuticles are treated with an oxidising agent, followed by a step involving the enzymatic hydrolysis of the insect cuticles using a proteolytic enzyme.
Hydrolysate comprising at least 40% by weight proteins based on the total weight of dry matter, at a maximum 10% by weight ash based on the total weight of dry matter, and a water-soluble protein content larger than 12,400 g/mol less than 50%.
Chitin comprising an amino acid content less than or equal to 55% by weight based on the total weight of dry matter, an ash content less than or equal to 3.5% by weight based on the total weight of dry matter, and a purity by difference greater than or equal to 35% or a colorimetric purity greater than or equal to 44%.
