Embodiment 1
[0032] Embodiment 1 prepares active protein powder
[0033] (1) get the housefly maggot that does not have residue in the abdomen that 1000g outdoors lead ovum to hatch;
[0034] (2) Rinse the selected fly maggots with 3‰ potassium permanganate solution for 10 minutes to sterilize the body surface, then rinse with pure water for 5 minutes, and use a 60-mesh filter cloth three-legged centrifuge to centrifuge and remove the fly maggot bodies Surface moisture;
[0035] (3) The fly maggots that have taken off body surface moisture are added by its weight the anti-browning agent sodium bisulfite of 1.2 ‰ and the antioxidant vitamin C of 0.2 ‰, grind into maggot pulp with refiner, and the grinding fineness is Pass 75 mesh sieve;
[0036] (4) Use 200 order filter cloth three-leg centrifuges to centrifugally filter the ground maggot pulp, filter out solids, and the filtered solids can be used as raw materials or feed additives for extracting chitin or chitosan;
[0037] (5) Put the...
Embodiment 2
[0040] Embodiment 2 prepares active protein powder
[0041] (1) Get 1000g of artificially raised housefly maggots with no residue in the abdomen and natural polypeptide content>5‰;
[0042] (2) Use 3‰ potassium permanganate solution to rinse the fly maggots for 10 minutes to sterilize the body surface, then rinse with pure water for 5 minutes, and then use a 60-mesh filter cloth three-legged centrifuge to remove the body surface moisture ;
[0043] (3) Add 1.5‰ anti-browning agent sodium bisulfite and 0.5‰ antioxidant vitamin C by weight to the maggots that have taken off body surface moisture, grind into maggot pulp with a refiner, and the refining fineness is through 80 mesh sieve;
[0044] (4) Use 200 order filter cloth three-leg centrifuges to centrifugally filter the ground maggot pulp, filter out solids, and the filtered solids can be used as raw materials or feed additives for extracting chitin or chitosan;
[0045] (5) Put the filtered permeate into a shallow containe...

[0048] Embodiment 3 prepares active protein powder
[0049] (1) Get 1000g of artificially raised housefly maggots with no residue in the abdomen and natural polypeptide content>5‰;
[0050] (2) Use 3‰ potassium permanganate solution to rinse the fly maggots for 10 minutes to sterilize the body surface, then rinse with pure water for 5 minutes, and then use a 60-mesh filter cloth three-legged centrifuge to remove the fly maggots body surface moisture;
[0051] (3) Add 1.8‰ anti-browning agent sodium bisulfite and 0.8‰ antioxidant vitamin C by weight to the maggots that have taken off body surface moisture, grind into maggot pulp with a refiner, and the refining fineness is through 85 mesh sieve;
[0052] (4) Use 200 order filter cloth three-leg centrifuges to centrifugally filter the ground maggot pulp, filter out solids, and the filtered solids can be used as raw materials or feed additives for producing chitin or chitosan;
[0053] (5) Put the filtrated permeate into a sha...
