preparation example Construction

[0028] The embodiment of the present application proposes a kind of preparation method of fermented earthworm meal, comprises the following steps:

[0029] The earthworms are ground for 100-140 minutes, the grinding temperature is gradually increased from 60-62° C. to 78-80° C., water is added during the grinding process, and an earthworm grinding liquid is obtained after the grinding is completed.

[0030] Fermentation is carried out at 78-82°C by adding a mixture to the earthworm grinding liquid, the mixture includes Staphylococcus carnosus with a mass percentage of 66-70% and neutral protease with a mass percentage of 30-34%, and the earthworms are obtained after fermentation and enzymolysis fermentation broth.

[0031] Phosphate is added to the earthworm fermentation liquid to adjust the pH value to 4.5-6.5, so as to maintain the stability of the earthworm fermentation liquid.

[0032] The earthworm fermented liquor added with phosphate is dried to make powder, and the fe...

Embodiment 1

[0063] 1. Select live earthworms and clean them.

[0064] 2. Grinding and physical crushing: the grinding temperature is 60-78°C, it takes 55 minutes to rise from 60°C to 78°C, and it takes 55 minutes to grind at 80°C for 85 minutes, and the total grinding time is 140 minutes. Add water during grinding, and the amount of water added is fresh 2.5 times the amount of earthworms.

[0065] 3. Fermentation and decomposition: the earthworm grinding liquid is first fermented, and a mixture of 15% of the filtrate mass is added during the fermentation, and the fermentation time is 7 days, and the fermentation temperature is 80° C.; the mixture includes Staphylococcus carnosus with a mass percentage of 66% and 34% Protease.

[0066] 4. Stable release: After the fermentation is completed, the earthworm fermentation broth is obtained, and dipotassium hydrogen phosphate with an amount of 3% of the mass of the earthworm fermentation liquor is added to the liquid, and the function release a...

Embodiment 2

[0069] 1. Select fresh and live earthworms and clean them;

[0070] 2. Grind the earthworms: the grinding temperature is 62-80°C, it takes 65 minutes to rise from 62°C to 80°C, and the grinding time is set at 82°C for 35 minutes, the total grinding time is 100 minutes, and water is added during the grinding period. 2.5 times the amount of live earthworms;

[0071] 3. Fermentation and decomposition: the earthworm ground liquid is firstly fermented, and a mixture of 18% of the filtrate mass is added during the fermentation, the fermentation time is 7 days, and the fermentation temperature is 78°C; the mixture includes Staphylococcus carnosus with a mass percentage of 68% and 32% Protease.

[0072] 4. Stable release: After the fermentation is completed, earthworm fermentation liquid is obtained, and disodium hydrogen phosphate with an amount of 4% of the mass of the earthworm fermentation liquid is added to the liquid, and the function release and stable activity operation are p...

Abstract

The invention provides fermented earthworm powder and a preparation method thereof. The preparation method comprises the following steps that earthworms are ground for 100-140 minutes, the grinding temperature is gradually increased to 78-80 DEG C from 60-62 DEG C, water is added in the grinding process, and earthworm grinding liquid is obtained after grinding is completed; a mixing agent is added into the earthworm grinding liquid and fermented at 78-82 DEG C, the mixing agent comprises, by mass, 66-70% of staphylococcus carnosus and 30-34% of neutral protease, and earthworm fermentation liquid is obtained after fermentation and enzymolysis; phosphate is added into the earthworm fermentation liquor to adjust the pH value to 4.5-6.5, and the stability of the earthworm fermentation liquor is maintained; and the earthworm fermentation liquor added with the phosphate is dried to prepare powder, thereby obtaining the fermented earthworm powder. Through proper grinding temperature and grinding time, protein is stably decomposed, release of active ingredients and beneficial ingredients of earthworms is promoted, and the broad-spectrum antibacterial and bacteriostatic performance can also be realized.

Description

technical field [0001] The application relates to the field of polypeptide preparation, in particular to fermented earthworm powder and its preparation method. Background technique [0002] Earthworms, also known as earthworms, have high edible and medicinal value, so they are more and more valued by people. As a new type of animal protein raw material, earthworm powder prepared from earthworms has the advantage of being easy to obtain and low in cost. Traditional earthworm powder processing methods include shade-drying (air-drying), sun exposure, high-temperature drying, and enzymatic hydrolysis. However, the prepared earthworm powder itself has low retention of active ingredients and beneficial ingredients. Contents of the invention [0003] The present application provides a preparation method of fermented earthworm powder, aiming to solve the problem of low retention of active components and beneficial components of earthworm powder. [0004] In the first aspect, the...
