摘要:
The present invention provides a method to convert insects or worms into nutrient streams, such as a fat-containing, an aqueous proteinaceous-containing and a solid-containing fraction. The method comprises the steps of: (a) squashing insects or worms thereby obtaining a pulp, (b) subjecting the pulp to enzymatic hydrolysis obtaining thereby a hydrolysed mixture, (c) heating the hydrolysed mixture to a temperature of 70-100° C., and (d) subjecting the mixture to a physical separation step, preferably decanting and/or centrifuging. The fat-containing fraction comprises at least 80 wt. % insect or worm fat of which at least 30 wt. % are saturated fats. The aqueous proteinaceous fraction can be dried to obtain dried proteinaceous material, which contains at least 45 wt. % insect or worm protein-derived matter and at most 25 wt. % insect or worm fat based on dry weight, and has a pepsin digestibility of at least 50%. The resulting nutrient streams can be used in food, feed and pharmaceutical industry.
摘要:
A method and system (1) for breeding insects, using a plurality of individual crates (9), 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 (3) housing the crates (9) that has an aeration system. A conveyor system (21) is included in the system for retrieving crates (9) from the climate area (3) and for returning same thereto. An observation system (27) for obtaining observations, including data and measurements, and downstream thereof a feedstock supply station (31) are arranged along the conveyor system (21). The method includes steps of aerating the substrate and the immature phases of insects with the aeration system, when in the climate area (3); periodically retrieving at least one individual crate (9) of the plurality of crates by the conveyor system (21) from the climate area (3) and passing it to the observation system (27); obtaining an observation of the substrate and the immature phases of insects in the at least one retrieved crate; and interpreting the observation of a retrieved individual crate and determining one of a requirement for adding an amount of supplementary feed stock, and a reason to withdraw the insects from further breeding for harvesting or discarding from further breeding.
摘要:
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.
