Problems solved by technology

[0004] On the one hand, earthworm extracts are currently prepared mainly by crushing or crushing earthworms for hydrolysis. During the hydrolysis process, exogenous enzymes need to be added or an acidic or alkaline environment is provided, and the extraction cost is high. And add extra enzymes, etc., so that the functional components in the earthworm extract will lose a lot, and the content of active components in the extract will be low
On the other hand, the existing earthworm extracts are mainly concentrated on crude extracts such as earthworm protein, and the progress in obtaining small molecule extracts such as amino acids and small peptides from earthworms is slow, and the extraction cost is high

Embodiment 1

[0031] The raw materials for preparing the earthworm extract are: 10Kg of clear water; 5Kg of adult fresh and alive Eisenia chinensis; 0.2Kg of table salt; 0.3Kg of food grade potassium sorbate;

[0032] The steps for preparing earthworm extract are as follows:

[0033] Step 1: Select 2 stainless steel standard barrels of appropriate size, the size of the big barrel is 400mm*400mm, the size of the small barrel is 300mm*300mm, the big barrel is the outer barrel, which is used for direct heating, and the small barrel is the inner barrel, which is used as a container for earthworm extract preparation. Add water to the outer barrel and pre-heat it. Fill the inner barrel with 10kg of clean water. The bottom of the inner barrel should not touch the bottom of the outer barrel. Cover the inner and outer barrel lids. After 2.5 hours of heating, when the water temperature in the inner barrel reaches 53±2°C, add 0.2Kg of edible salt to the inner barrel , stir to fully dissolve;

Abstract

The invention discloses an earthworm extract. The earthworm extract comprises the following substances by content: 44-60 g / L of hydrolyzed amino acid, 24-32 g / L of free amino acid and 60-90 g / L of small peptides. The preparation method comprises the steps of starting autolyzed hydrolysis reaction on earthworms in saline water heated in water bath to hydrolyze earthworms; and finally, filtering andcooling to obtain supernate of an earthworm hydrolyzed mixed solution at a normal temperature so as to obtain brown liquid which is the earthworm extract. The earthworm extract can be widely appliedto the industries of pharmacy, health-care food, cosmetics, food, feed additives and the like, the preparation process is simple, the cost is low, functional components of the extract are high, and the storage time is long.

Description

technical field [0001] The invention relates to an earthworm extract and a preparation method thereof. Background technique [0002] Earthworms, commonly known as earthworms or eels, are representative animals of the phylum Oligochaeta. Through people's experiments and research, it is found that earthworms have multiple functions. Earthworms are rich in protein, amino acids, vitamins and trace elements. Now various extracts of earthworms have been widely used in pharmaceuticals, cosmetics, health products, light chemical industry, and breeding. [0003] At present, earthworm extracts processed and produced by freezing, air-drying, soaking and other methods include: pharmaceutical raw material lumbrokinase, earthworm thrombolytic enzyme, liquid lumbrokinase, earthworm antioxidant enzyme complex, superoxide dismutase, amino acid solid, earthworm Amino acid polypeptide, earthworm collagen, earthworm essence. Amino acid liquid, medium activity earthworm powder, high activity e...
