Abstract: A method to convert insects or worms into nutrient streams, such as a fat-containing, an aqueous protein-containing and a solid-containing fraction, includes (a) squashing insects or worms thereby obtaining a pulp, wherein the insects or worms are reduced in size, (b) heating the pulp to a temperature of 70-100° C., and (c) subjecting the heated pulp to a physical separation step, preferably decanting and/or centrifuging. The method does not comprise enzymatic treatment of the pulp. The fat-containing fraction comprises at least 80 wt. % insect or worm fat of which at least 40 wt. % are saturated fats. The aqueous protein fraction can be dried to obtain dried protein material, which contains at least 50 wt. % insect or worm protein-derived matter and at most 25 wt. % insect or worm fat based on dry weight. The protein has a pepsin digestibility of at least 50%. The resulting nutrient streams can be used in food, petfood, feed and pharmaceutical industry.

Abstract: A method and system for breeding insects, using a plurality of individual crates, wherein at least a portion of each crate is filled with a substrate, containing feed stock, and immature phases of insects. Also provided is a climate area housing the crates that has an aeration system. A conveyor system is included in the system for retrieving crates from the climate area and for returning same thereto. An observation system for obtaining observations, including data and measurements, and downstream thereof a feedstock supply station are arranged along the conveyor system.
