Definitions
- the present invention relates to a method of treating insects.
- the invention also relates to powders, in particular a powder that can be obtained by the insect treatment method according to the invention, and the use of these powders in food, especially in animal feed.
- Powders made from animals have long been used in animal feed.
- fish meal which is one of the main sources of protein in animal feed.
- Fishmeal is very rich in animal protein (rich in amino acids such as lysine and methionine) that are easy to digest.
- a growing demand accompanied by a limited supply has resulted, in particular, in significantly increasing its price.
- Insect flours offer natural protein sources for replacement and the possibility of mass production with minimal ecological footprint.
- some beetles such as Tenebrio molitor, have the advantage of being suitable for intensive mass production.
- application WO2016 / 108037 describes in particular a coleopteran powder comprising at least 67% by weight of proteins and at least 5% by weight of chitin, which can be used in animal feed.
- chitin means any type of chitinic derivative, that is to say of a polysaccharide derivative comprising N-acetylglucosamine units and D-glucosamine units, in particular the chitin-polypeptide copolymers (sometimes referred to as “chitin-polypeptide composite”). These copolymers may also be associated with pigments, often of the melanin type.
- Chitin is the second most synthesized polymer in the world after cellulose. Indeed, chitin is synthesized by many species of the living world: it is partly the exoskeleton of crustaceans and insects and the side wall that surrounds and protects mushrooms. More particularly, in insects, chitin thus constitutes 3 to 60% of their exoskeleton.
- chitin is generally considered a compound difficult to digest by some animals.
- the invention thus relates to a method of treating insects comprising separating the cuticles from the soft part of the insects, wherein the separation is carried out by means of a band separator.
- insects means insects at any stage of development, such as adult, larval, or pupal stage.
- the cuticle is the outer layer (or exoskeleton) secreted by the epidermis of insects. It usually consists of three layers: the epicuticle, the exocuticle and the endocuticle.
- soft part refers to the flesh (including muscles and viscera) and the juice (including body fluids, water and haemolymph) of the insects. In particular, the soft part does not consist in the juice of insects.
- insects used in the process according to the invention are in a larval stage.
- insects used in the process according to the invention are edible.
- the preferred insects for carrying out the process according to the invention are, for example, Coleoptera, Diptera, Lepidoptera, Isoptera, Orthoptera, Hymenoptera, Boletoptera, Hemiptera, Heteroptera, Ephemeroptera and moptera, preferably beetles, Diptera, Orthoptera, Lepidoptera or mixtures thereof, more preferably beetles.
- the beetles preferentially used in the process according to the invention belong to the families Tenebrionidae, Melolonthidae, Dermestidae, Coccinellidae, Cerambycidae, Carabidae, Buprestidae, Cetoniidae, Dryophthoridae, or their mixtures.
- these are the following beetles: Tenebrio molitor, Alphitobius diaperinus, Zophobas morio, Tenebrio obscurus, Tribolium castaneum and Rhynchophorus ferrugineus, or mixtures thereof.
- band separator is meant a device for separating the solid portion of the soft portion of a product, and which comprises a clamping band (or pressing belt) and a perforated drum.
- step 2 of the detailed insect treatment method according to the invention The separation of the cuticles from the soft part of the insects is more fully described in step 2 of the detailed insect treatment method according to the invention hereinafter.
- the cuticles obtained at the end of this separation step has a high chitin content of the order of 10 to 30% by weight on the total weight of cuticles, as indicated below.
- the step of separating cuticles from the soft part is carried out without any prior step of grinding insects, particularly in the form of particles, has been performed.
- the insect treatment method according to the invention may furthermore comprise a stage of maturation of the soft part of the insects.
- stage of maturation of the soft part of the insects it is more particularly a step during which the soft part of the insects is subjected to agitation.
- step 3 is more fully described in step 3 of the detailed insect treatment method according to the invention hereinafter.
