Abstract

FIELD: biotechnology. SUBSTANCE: invention relates to obtaining flour from black soldier fly larvae (lat. Hermetia illucens). Method for obtaining flour from black soldier fly larvae comprises growing larvae in premises, in which temperature not less than 15 °C and not more than 25 °C is maintained, in containers of 2-4 kg on food substrate, with subsequent harvesting of larvae before their pupation stage. Then selection of healthy individuals and washing with running water is carried out, after which blanching is performed by immersing larvae into boiling water for 1 min and rapid cooling. Then drying at temperature 50-70 °C with air blowing 0.5-2.0 m/s duration 4-6 hours to moisture content of final product not more than 10% is carried out. Then larvae are cooled to room temperature, defatted with hot pressing oil press to content of raw fat in them not more than 10% and cake is obtained. Then cake is crushed to state of flour using mill, sifted and packed into hermetic packaging, and stored in dry cool place at temperature not higher than 20 °C. EFFECT: obtaining high-quality flour from cake of black soldier fly larvae with moisture content not more than 10%, suitable for feed purposes. 1 cl, 2 dwg, 1 ex

A method for producing flour from the larvae of the black soldier fly Hermetia illucens, including growing the larvae in a room where the temperature is maintained at a minimum of 15 °C and no more than 25 °C, in 2-4 kg containers on a food substrate, followed by collecting the larvae before the pupation stage, then a thorough inspection is carried out with the selection of healthy individuals and washing with running water, after which they are blanched by immersing the larvae in boiling water for 1 minute and quickly cooled, after which they are dried at a temperature of 50-70 °C with a blowing of 0.5-2.0 m / s for 4-6 hours until the moisture content of the final product is no more than 10%, after drying is complete, the larvae are cooled to room temperature, degreased with a hot-pressed oil press until the crude fat content in them is no more than 10% and cake is obtained, then the cake is ground to a flour state using a mill, sifted and packaged in a sealed package and store in a cool, dry place at a temperature not exceeding 20 °C.

Description

Field of technology to which the invention relates The invention relates to biotechnology, in particular to the production of flour from black soldier fly larvae (Latin: Hermetia illucens). State of the art A method for obtaining biomass of Musca domestica larvae for producing feed flour is known. The method is characterized in that Musca domestica larvae are introduced into a container with a substrate at the rate of 0.4-0.6 g of larvae per 1 kg of substrate and cultivated, wherein the substrate contains cobalt and/or selenium at the rate of 10-20 ml of a microelement solution per 1 kg of substrate. After two days, the migrated larvae are collected from the tray (Patent No. 2671165 C1 Russian Federation, IPC A01K 67/033, A23K 10/20, A23K 10/18. Method for obtaining biomass of Musca domestica larvae for obtaining feed flour: No. 2017137041: declared 10/23/2017: published 10/29/2018 / O. S. Larionova, E. A. Faust, Ya. B. Drevko [et al.]; applicant Federal State Budgetary Educational Institution of Higher Education "Saratov State Agrarian University named after N.I. Vavilov". Analogue). This method does not disclose the technology for obtaining feed flour. A known method for producing a protein feed supplement involves mixing grain raw materials, such as wheat bran, with a protein component. The protein component is prepared from live insects, specifically cockroaches of the species Nauphocta cinerea, which are cooled to a state of deep suspended animation and then ground to a homogeneous mass. The resulting protein component is mixed with the bran in a ratio of 1:(2:4). A disadvantage of this method is the lack of heat treatment of the insect biomass, which does not guarantee microbiological purity. Another feature of adult insects is the presence of a dense chitinous cover, therefore the resulting substrate will contain large inclusions of chitin (Patent No. 2038798 C1 Russian Federation, IPC A23K 1/00. Method for producing a protein feed additive: No. 5056151/15: declared 07/29/1992: published 07/09/1995. Analogue). The closest method in essence and technical characteristics is the preparation of a feed supplement from fly larvae. Housefly eggs are added to pig manure. On days 3, 4, and 5, the manure layers are removed, and the fly larvae in the remaining layer are ground to a paste, packed into containers, and sterilized using the following settings: 5 minutes at a temperature of 30 to 100°C, 15 minutes at a temperature of 100 to 120°C, and 35 minutes at 120 to 150°C, then cooled. The feed supplement contains up to 50-60% protein and up to 25-30% fat. The energy consumption per kg of feed supplement is 0.18 kW, and the shelf life is 1 year. In feed meal from fly larvae the protein content is lower and amounts to 30-40%, the energy consumption for the preparation of 1 kg is 1.6 kW (Author's certificate No. 1517904 A1 USSR, IPC A23K 1/00. Method for the preparation of feed additive from fly larvae: No. 4310279: declared. 09.28.1987: published. 10.30.1989 / T. V. Erofeeva, P. P. Grigoriev, A. K. Greinshtein, A. V. Kuzmina; applicant INSTITUTE OF MEDICAL AND BIOLOGICAL PROBLEMS, FISHING COLLECTIVE FARM "OKTOOBER" ESSR. Prototype). The disadvantage of this method is the lack of washing of the larvae from impurities of the substrate (manure) and strict temperature treatment conditions, which affect the biological characteristics of the protein. Disclosure of invention The present invention provides a method for producing flour from black soldier fly larvae. The black soldier fly (Hermetia illucens) is a species of fly from the family of black soldier flies. This species of fly is not traditionally used as food. However, Russian Government Decree No. 2761-r of October 10, 2023 approved amendments to the list of agricultural products, according to which the following species are included in the list of agricultural products: 1. Black soldier fly. 2. Black soldier fly eggs. 3. Black soldier fly larvae. 4. Flour and granules from black soldier flies and their larvae. The technical result that can be achieved with the help of the proposed invention is to obtain flour from the cake of black soldier fly larvae (Hermetia illucens) with a moisture content of no more than 10%, suitable for feed purposes. The technical result is achieved using a method for obtaining flour from the larvae of the black soldier fly Hermetia illucens, includingrearing larvae in a special room at a temperature of about 30°C in 2-4 kg containers on a food substrate, followed by collecting the larvae before the pupation stage, then thoroughly inspecting and washing with running water, after which they are blanched by immersing the larvae in boiling water for 1 minute and quickly cooled, after which they are dried at a temperature of 50-70°C with a blowing of 0.5-2.0 m / s until the moisture content of the final product is no more than 10%, after drying is complete, the larvae are cooled to room temperature, degreased with a hot-pressed oil press
