Abstract

A method and system for producing a low-fat protein meal from an insect-based raw material involve providing an insect-based raw material, which is optionally reduced in size. The insect-based raw material is pumped to a heating step, in which the material is heated to 75 to 100° C. Optionally, the heated insect-based raw material may be submitted to a buffer/mixing tank. The heated insect-based raw material is subjected to one or more separation steps. Then, the solid phase and at least part of the aqueous protein-containing fraction, which is optionally concentrated, is subjected to drying to provide the insect-based, low-fat protein meal. Water or separated liquid heavy phase may be added to the feed upstream of the separation steps. Alternatively, a pre-separation step is included before a main separation step to provide a protein meal with reduced fat content. No enzymes or chemicals need to be added during the method.
