Embodiment 1

[0013] (steps 1, 2, 3 can refer to the Chinese invention patent application whose publication number is CN101117613 applied by the applicant)

[0014] 1. Microwave drying and sterilization of live Tenebrio molitor

[0015] Microwave working chamber: the temperature is 30-80°C, the drying time is 15 minutes, and the moisture content of dried Tenebrio molitor is 8.14%.

[0016] Explanation: If the moisture content is too high, it is easy to form a continuous phase water film on the surface of the particles, which affects the degreasing rate, and at the same time causes excessive moisture in the degreasing insect body, which will cause sticking phenomenon when processing ultra-fine powder. Therefore, the moisture content should be controlled at 6%-10%.

[0017] 2. Crush the dried Tenebrio molitor and sieve it with 20 mesh.

[0018] 3. Take 16kg of Tenebrio molitor powder through a 20-mesh sieve and carry out supercritical CO2 fluid extraction degreasing to obtain 12kg of defatt...

Embodiment 2

[0050] (steps 1, 2, 3 can refer to the Chinese invention patent application whose publication number is CN101117613 applied by the applicant)

[0051] 1. Microwave drying and sterilization of live Tenebrio molitor

[0052] Microwave working chamber: the temperature is 70-85°C, the drying time is 21 minutes, and the moisture content of dried Tenebrio molitor is 6% after drying.

[0053] 2. Crush the dried Tenebrio molitor and sieve it through a 14-mesh sieve.

[0054] 3. Weigh 20kg of its dry product and carry out supercritical CO 2 Fluid extraction degreasing. 15.36 kg of defatted worm bodies were obtained.

[0055] 4. Pre-crushing the defatted worms to 100 mesh.

[0056] 5. The pre-crushed Tenebrio molitor powder is crushed by microgravity supersonic collision. The time was 40 minutes, and 12.13 kg of superfine powder was obtained.

Embodiment 3

[0058] (steps 1, 2, 3 can refer to the Chinese invention patent application whose publication number is CN101117613 applied by the applicant)

[0059] 1. Microwave drying and sterilization of live Tenebrio molitor.

[0060] Microwave working chamber: the temperature is 73-84°C, the drying time is 10 minutes, and the moisture content of dried Tenebrio molitor is 10% after drying.

[0061] 2. Crush the dried Tenebrio molitor and sieve it through a 30-mesh sieve.

[0062] 3. Weigh 15kg of sieved Tenebrio molitor body for supercritical CO 2 Fluid extraction and degreasing yielded 11.4 kg of defatted Tenebrio molitor bodies.

[0063] 4. Pre-crushing the defatted Tenebrio molitor to 80 mesh.

[0064] 5. The defatted Tenebrio molitor powder was collided and pulverized by microgravity supersonic airflow for 40 minutes to obtain 8.89 kg of ultrafine micronized Tenebrio active protein powder.

[0065] The airflow pulverizer used in the present invention can be selected in the existi...

Abstract

The invention discloses a method for separating yellow meal worm dried goods to prepare ultramicro yellow meal worm protein powder and shell material, which comprises the steps that: step 1. yellow meal worm degreased dried goods is prepared, and parameter requirements are 6-10 percent of water content, 14-30 meshes of graded granularity and less than 5 percent of fat residue; step 2. the yellow meal worm dried goods obtained from the step 1 is ground into 60-100 meshes; step 3: the powder of the yellow meal worm dried goods obtained from the step 2 is transferred to a super-micro fluid jet mill; the protein is collected after being pulverized by air flow and the ultramicro yellow meal worm protein powder is obtained; the rest residue is the shell material which is rich in chitin. The method can not only well realize the separation of yellow meal worm protein and the shell material, but also prepare the yellow meal worm protein powder with high pureness, fine granularity and no solvent residue, which starts a new way in the development of yellow meal worm resource.

Description

technical field [0001] The invention belongs to the processing technology of insect agricultural products, and specifically relates to a method for separating and preparing supermicro Tenebrio molitor protein powder and shell substances. Background technique [0002] Tenebrio molitor has the characteristics of fast growth and high reproduction coefficient, and its main food is crop waste. Tenebrio molitor contains a variety of nutrients, and the protein content in its dry product is as high as 57%, and the rest is shell material, fat and carbohydrates, and the shell material is rich in chitin. At present, the application of Tenebrio molitor is limited to the bait of special farmed animals, comprehensive deep processing is still blank, and the development of protein powder made from Tenebrio molitor is still in its infancy. In the process of producing traditional protein powder, pressing or chemical methods are used to degrease and separate shell substances, and ordinary pul...
