preparation example Construction

[0028] The embodiment of the present application proposes a preparation method of fermented earthworm powder, comprising the following steps:

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

[0030] Add a mixture to the earthworm grinding liquid and ferment at 78-82°C. The mixture includes 66-70% by mass of Staphylococcus meatus and 30-34% by mass of neutral protease. After fermentation and enzymolysis, earthworms are obtained fermentation broth.

[0031] Phosphate was added to the earthworm fermentation broth to adjust the pH value to 4.5-6.5 to keep the earthworm fermentation broth stable.

[0032] The earthworm fermentation broth added with phosphate is dried to prepare powder to obtain fermented earthworm powder.

[0033] In the grinding step, the earthworms can ...

Embodiment 1

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

[0064] 2. Grinding physical crushing: the grinding temperature is 60-78 °C, it takes 55 minutes to increase from 60 °C to 78 °C, set at 80 °C during grinding for 85 minutes, 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.

Abstract

The application provides a fermented earthworm powder and a preparation method thereof, comprising the following steps: grinding the earthworms for 100-140 minutes, gradually increasing the grinding temperature from 60-62°C to 78-80°C, adding water during the grinding process, and Obtaining the earthworm grinding liquid; adding a mixture to the earthworm grinding liquid and fermenting at 78-82°C, the mixture includes 66-70% by mass of Staphylococcus carnosus and 30-34% by mass of neutral protease, fermenting After enzymolysis, earthworm fermentation liquid is obtained; phosphate is added to the earthworm fermentation liquid to adjust the pH value to 4.5-6.5, and the stability of the earthworm fermentation liquid is maintained; the earthworm fermentation liquid added with phosphate is dried to make powder, and fermented earthworm powder is obtained. Through proper grinding temperature and grinding time, the protein can be decomposed stably, and the release of the earthworm's own active ingredients and beneficial ingredients can be promoted, and it also has broad-spectrum antibacterial and antibacterial performance.

Description

technical field [0001] The present application relates to the field of polypeptide preparation, in particular to fermented earthworm powder and a preparation method thereof. Background technique [0002] Earthworms, also known as earthworms, have high edible and medicinal value, so they have been paid more and more attention by people. The earthworm powder prepared from earthworms is used as a new type of animal protein raw material, and has the advantage of easy acquisition and low cost. Traditional earthworm powder processing methods include shade-drying (air-drying), sun exposure, high-temperature drying, and enzymatic hydrolysis. However, the prepared earthworm powder has low retention of its own active components and beneficial components. SUMMARY OF THE INVENTION [0003] The present application provides a preparation method of fermented earthworm powder, which aims to solve the problem of low retention of active components and beneficial components of earthworm pow...
