Problems solved by technology

[0004] Existing literature materials are solvent extraction of Tenebrio molitor after pulverization. The focus is on how to obtain Tenebrio molitor oil, and the extraction of oil is not complete. After obtaining useful Tenebrio molitor oil, the rest is transformed into yellow powder containing oil Insect powder, which is crushed during extraction, does not yield degreased whole insects
Whole Tenebrio molitors available in the market cannot be stored for a long time because they contain a certain amount of oil

Embodiment 1

[0020] 1. Microwave drying of Tenebrio molitor. After the Tenebrio molitor was cleaned, microwave drying was carried out at a temperature of 50 degrees and a drying time of 10 minutes. After drying, the moisture content of the Tenebrio molitor was 9%.

[0021] 2. Extraction. Put 500 g of dried whole insects into a subcritical extraction tank, and use a vacuum pump to exhaust the air in the extraction tank to a degree of vacuum below -0.085 MPa. Use the pressure difference to inject the mixture of butane and dimethyl ether (10:1) in the solvent tank into the extraction tank, the material-solvent ratio is 1:4, the extraction temperature is 35°C, the extraction pressure is 0.4MPa, and the extraction time is 20 minutes . After the extraction, the extract enters the separation tank from the extraction tank.

[0022] 3. Separation. Evaporate under reduced pressure in the separation tank, the temperature is 30 degrees, and the vaporized solvent is compressed and liquefied by the ...

Embodiment 2

[0025] 1. Microwave drying of Tenebrio molitor. After the Tenebrio molitor is cleaned, microwave drying is carried out at a temperature of 55 degrees and a drying time of 15 minutes. After drying, the moisture content of the Tenebrio molitor is 9%.

[0026] 2. Extraction. Put 5Kg of dried whole insects into a subcritical extraction tank, and use a vacuum pump to exhaust the air in the extraction tank, and the vacuum degree is below -0.085 MPa. Use the pressure difference to inject butane and dimethyl ether (10:1) into the extraction tank, the material-solvent ratio is 1:4, the extraction temperature is 35°C, the extraction pressure is 0.4MPa, and the extraction time is 20 minute. After the extraction, the extract enters the separation tank from the extraction tank. The extraction was then repeated 2 times.

[0027] 3. Separation. Evaporate under reduced pressure in the separation tank, the temperature is 40 degrees, and the vaporized solvent is compressed and liquefied by...

Embodiment 3

[0030] 1. Microwave drying of Tenebrio molitor. After the Tenebrio molitor is cleaned, microwave drying is carried out at a temperature of 55 degrees and a drying time of 10 minutes. After drying, the moisture content of the Tenebrio molitor is 8%.

[0031] 2. Extraction. Put 5Kg of dried whole insects into a subcritical extraction tank, and use a vacuum pump to exhaust the air in the extraction tank, and the vacuum degree is below -0.085 MPa. Use the pressure difference to inject the mixture of butane and dimethyl ether (10:2) in the solvent tank into the extraction tank, the material-solvent ratio is 1:5, the extraction temperature is 45°C, the extraction pressure is 0.45MPa, and the extraction time is 30 minutes . After the extraction, the extract enters the separation tank from the extraction tank. The extraction was then repeated 2 times.

[0032] 3. Separation. The decompression evaporation is carried out in the separation tank, the temperature is 45 degrees, and th...

Abstract

The invention discloses a method for comprehensively utilizing tenebrio molitor. The method comprises the steps of extracting a whole tenebrio molitor through a subcritical extraction method, and obtaining tenebrio molitor oil and dried defatted tenebrio molitor. The obtained dried tenebrio molitor after complete degreasing is not liable to deteriorate and mildew, and is easier to store and free of any residual chemical reagents; the extraction pressure is low, and the integrity of the tenebrio molitor body is better maintained. The method uses low-temperature extraction to obtain the tenebriomolitor oil, and unsaturated fatty acid and the like are not easily destroyed; low-temperature degreasing ensures that protein is not denatured, and nutritional value of tenebrio molitor protein powder is retained to the utmost extent.

Description

technical field [0001] The invention belongs to the technical field of deep processing of insect agricultural products, and in particular relates to comprehensive utilization of Tenebrio molitor, processing Tenebrio molitor into insect oil, defatted whole insects, defatted insect powder and the like. Background technique [0002] Tenebrio molitor, commonly known as mealworm, is an excellent nutrient-rich insect resource. Tenebrio molitor has strong adaptability, fast growth and development, and low feeding cost. The development of Tenebrio molitor resources has become the third largest new insect industry after silkworm and bee. Its main functional components include a variety of proteins and amino acids, fats and fatty acids, chitosan, vitamins, minerals, and flavonoids. People have carried out a lot of research on the application of Tenebrio molitor. [0003] Tenebrio molitor oil contains a large amount of unsaturated fatty acids, accounting for 80% of the total fatty aci...
