Process for the production of an insect substrate, insect substrate and uses thereof

A process for the production of an insect substrate is provided, which comprises or consists of the steps of sterilizing a substrate comprising lignocellulose, mixing the sterilized substrate comprising lignocellulose with a lignin-degrading fungus to form a solid state mixture and incubating the solid state mixture to allow a solid state fermentation, wherein enzymes produced by the fungus convert the solid state mixture to an insect substrate. The process is characterized in that it does not comprise a step in which the substrate comprising lignocellulose is subjected to a delignification treatment involving an addition of NaOH to the substrate comprising lignocellulose before the solid state fermentation. The process has the advantage that it allows an easier, faster, more efficient, lower-cost and more sustainable and industrial-scale production of an insect substrate from a substrate comprising lignocellulose than known processes. Moreover, an insect substrate is provided and uses thereof are proposed.
