Problems solved by technology

Because earthworm humus, animal feces, soil bacteria, etc., and the decomposition products of these substances are eaten, earthworms become carriers of many bacteria and viruses, and untreated protein extraction has potential safety hazards
Moreover, the protein quality currently extracted is poor, and various medicinal ingredients in earthworms have not been effectively extracted

Embodiment 1

[0021] The invention discloses a method for extracting an earthworm extract, which mainly includes the following steps:

[0022] Step 1, earthworm cleaning, the earthworms are cleaned, and the sludge on the body surface and the feces in the body are removed.

[0023] Step 2, earthworms break the wall, soak the cleaned earthworms in normal saline, the volume ratio of earthworms to normal saline is 1:1.5-2, the soaking time is 20-60 minutes, after soaking, the earthworm liquid flows from the earthworms The outer cuticle is broken and flowed out, and the cuticle of the earthworm is removed by filtration to obtain the earthworm fluid. A large number of experimental results show that a good wall-breaking effect can be fully achieved when the wall-breaking time is 20-60 minutes after soaking.

[0024] Step 3 is to remove salt, and the earthworm liquid obtained in step 2 is desalted. The method for removing the salt is as follows: the earthworm solution is passed through the osmoti...

Abstract

The invention relates to a method for extracting earthworm extracts. The earthworms are cleaned to remove sludge on the body surface and feces in the body; the cleaned earthworms are soaked in normal saline, and the volume ratio of the earthworms to the normal saline is 1: 1.5‑2, earthworms break the wall after soaking, filter to remove earthworm cuticles, and obtain earthworm liquid; add acetic acid solution to the earthworm liquid, and fully mix according to the ratio of the volume of earthworm liquid and acetic acid solution to 1:2‑3 to obtain a mixed liquid Rotary evaporation of the mixed solution, concentrated to obtain a concentrated solution; the concentrated solution is dried to obtain an extract powder; the extract powder is sterilized to obtain an edible earthworm extract. The earthworm extract extracted by this extraction method has no sludge, does not carry bacteria and viruses, the protein content in the earthworm extract is high, and the medicinal ingredients are effectively extracted, which is convenient for consumption; quick.

Description

technical field [0001] The invention relates to the field of earthworm extraction, in particular to an extraction method of earthworm extract. Background technique [0002] The protein content of earthworms is up to 70%, rich in trace elements such as phosphorus, calcium, iron, potassium, zinc, copper, and various vitamins. In 1837, the biologist Darwin called it the most valuable animal on earth. Chinese medicine research shows that Earthworms contain various medicinal ingredients such as dilongsu, dilongjietoxin, xanthine, antihistamine and vitamin B. Therefore, earthworms are widely used in fields such as pharmacy, light chemical industry, and food. They can not only be used as animal feed and produce medicines and cosmetics, but also can be eaten by humans. Earthworm food is very popular in Taiwan, Southeast Asia, the United States, Canada and other countries. Therefore, earthworm farming is getting more and more attention. [0003] At present, the extraction of earthw...
