Abstract

The present invention relates to a method for processing edible earthworm, in particular a method for preparing dried earthworm powder and its hydrolyzate. Said method includes the following steps: firstly, spuring earthworm to defecate, cleaning, freeze-drying at ultra-low temp., pulverizing and sieving to obtain the dried earthworm powder; soaking the cleaned earthworm in aqueous solution of cirtric acid, then adding acidic proteinase and plasmin, making enzymolysis for one day, then adding white granular sugar and making continuous enznymolsis, filteirng to obtain its hydrolyzate, high pressure sterilziing to obtian the invented product with rich nutrients. Said edible dried earthworm powder and hydrolyzate have no stinking smell, are easy to store, and can completely reach edible standard.

Description

The preparation method of edible earthworm powder and hydrolyzate

The present invention relates to the processing method of edible earthworm, particularly make the method for its dry powder and hydrolyzate

Edible and the medical value of earthworm is more and more paid attention to by people, will become the indispensable senior tonic of people soon.Traditional earthworm dry powder is processed with method of making herbs dry gradually in the shade (aeration drying), sunlight be exposed to the sun method, high-temperature oven drying method, and the earthworm dry powder that these methods are handled not only nutrition loses in a large number, and the flavor stink smell is smelly, is difficult to eat.And the hydrolyzate of earthworm the most effective be enzymatic isolation method, percent hydrolysis can reach about 80%, stink smell is smelly but its liquid is also distinguished the flavor of, and is not easy to store, is difficult to do edible raw material.

For overcoming the above-mentioned defective of prior art, the present invention aims to provide a kind of new edible earthworm powder and the preparation method of hydrolyzate, the dry powder and the hydrolyzate that adopt this method to make, and not only nutrition is not lost, and does not still have stench flavor, is easy to deposit, and reaches food sanitation standard fully.

For achieving the above object, the present invention tells mud with short its defecation of edible earthworm earlier, cleans then and processes.Make its dry powder adopt superfreeze technology drying again crushing screening get final product finished product.Making its hydrolyzate is that the earthworm of will handle is immersed in (5% citric acid) in the aqueous citric acid solution, then by 3/10000ths and ten thousand of earthworm weight/adding acid protease and fibrinolysin, carry out enzymolysis about one day, and then the centesimal white granulated sugar that adds earthworm weight continued enzymolysis four hours, hydrolyzate can be filtered out, behind autoclaving, finished product can be got again.

Owing to take above-mentioned technical solution, processing and eating earthworm dry powder of the present invention and hydrolysis dissolution method are simple and easy to do, and resulting product is nutritious not to have stench the flavor again, still is easy to deposit, and reaches food sanitation standard fully.

Elaborate specific embodiments of the invention below again.

Earlier edible earthworm being put into water adds a little salt and stimulates its defecation to tell mud to clean to be processed again:

Its dry powder of desire system is put into the earthworm of handling and is reentered pulverizer after the cryogenic temperature freezing drying case back warp-153 degree drying and be ground into powder, after sieving its finished product.

Its hydrolyzate of desire system, immerse fully in 5% aqueous citric acid solution after the earthworm of handling weighed, if earthworm weight is a myriagram, just in solution, add three gram acid proteases and a gram fibrinolysin again, enzymolysis adds a hectogram white granulated sugar again after one day, continued enzymolysis four hours, the earthworm hydrolyzate of gained is finished product through autoclaving after filtration then.

Claims

1, the preparation method of a kind of edible earthworm powder and hydrolyzate is earlier mud to be told in short its defecation of earthworm, cleans then and processes, it is characterized in that:

A, make earthworm that dry powder will handle and put into cryogenic temperature freezing drying case back warp-153 and spend and reenter pulverizer one-tenth powder after the drying and sieve and promptly get its finished product;

After weighing, the earthworm that b, making hydrolyzate will be handled is immersed in fully in 5% aqueous citric acid solution, add in the aqueous solution again the acid protease and ten thousand of earthworm weight 3/10000ths/ fibrinolysin, enzymolysis adds one of earthworm weight percent again after one day white granulated sugar continued enzymolysis four hours, and the earthworm hydrolyzate of gained promptly gets its finished product through autoclaving after filtration then.
