[0027] In order to solve the problem of easy agglomeration in the milling process of grain insects, the present invention proposes a preparation method of grain insect powder, which comprises the following steps:
[0028] S1: Take grain worms with a water content below 10%, mix them with a sodium hydroxide solution with a pH value above 10.5 at a ratio of 1:8 to 12 (g / mL) after winnowing, and place the mixture in a heating device Heat until boiling, keep boiling for 5-15 minutes, then cool to room temperature, filter, and take the azeotropic grain worm for later use;
[0029] S2: wash the grain worms after azeotropy repeatedly with clear water, and measure the pH of the clear water after washing the grain worms with pH test paper, when the clear water after washing the grain worms is neutral, stop washing;
[0030] S3: put the grain worms washed to neutral in an oven, set the temperature of the oven at 70-90°C, and bake at this temperature for 3-5 hours, so that the water cont...

[0035] A method for preparing grain insect powder, comprising the following steps:
[0036] S1: Get 1Kg of grain worms, mix it with 10L of sodium hydroxide solution with a pH value of 12, then azeotrope for 10min, then filter, and take the azeotropic grain worms for subsequent use;
[0037] S2: rinse the grain worms after the azeotropy repeatedly with clear water until the clear water after washing is neutral;
[0038] S3: place the grain worms treated in S2 in an environment of 80°C and dry for 4 hours to obtain dried grain worms;
[0039] S4: uniformly mix 25g talcum powder and 75g tryptophan to obtain an auxiliary material; uniformly mix the auxiliary material with dried grain worms, and place the mixture in an ultrafine pulverizer for 30 minutes to obtain grain insect powder;
[0040] S5: adopting 400MHz microwave to dry and sterilize the grain insect powder to obtain the final product.

[0042] A method for preparing grain insect powder, comprising the following steps:
[0043] S1: Get 1Kg of grain worms, mix it with 12L of sodium hydroxide solution with a pH value of 10.5, then azeotrope for 15min, then filter, and take the azeotropic grain worms for subsequent use;
[0044] S2: rinse the grain worms after the azeotropy repeatedly with clear water until the clear water after washing is neutral;
[0045] S3: place the grain worms treated in S2 in an environment of 90°C and dry for 3 hours to obtain dried grain worms;
[0046] S4: uniformly mix 25g talcum powder with 100g lysine and 50g valine to obtain an auxiliary material; uniformly mix the auxiliary material with dried grain worms, and place the mixture in an ultrafine pulverizer for 20 minutes to obtain grain insect powder ;
[0047] S5: adopting 500MHz microwave to dry and sterilize the grain insect powder to obtain the final product.
