Background technology
Modern study shows, is that the liquid extract that raw material extracts is to contain the goods that enrich the active bio composition with the Lumbricus, has multiple efficacies with the product of its preparation.But the preservation to the goods that contain the active bio composition in the prior art is an a great problem always, in the existing textbook explanation is arranged, if, then can destroy the active bio composition in the goods with surpassing 37 ℃ high temperature to the goods that contain the active bio composition sterilization that carries out disinfection; If adopt the low temperature disinfection by ultraviolet light, thorough kill bacteria, the biological product shelf-life that obtains is very short, often will go bad in several days; Can not solve the preservation problem even add antiseptic.Therefore be that the biological product that raw material obtains can't carry out production and selling as product with the Lumbricus, make the value of Lumbricus can't obtain utilizing.
Summary of the invention
The objective of the invention is to, a kind of sterilizing methods of earthworm liquid extraction is provided.This method can be carried out the thorough disinfection sterilization and do not destroyed its active component to the goods that contain the active bio composition that Lumbricus is extracted.The problem that has solved earthworm liquid extraction and be difficult to preserve with the goods of its preparation.
Technical scheme of the present invention.The sterilizing methods of earthworm liquid extraction is characterized in that: this method comprises following step:
A, add 5~20% mashed garlic juice by Lumbricus weight in earthworm liquid extraction, carry out disinfection with the steam that is not less than 100 ℃, gains are the A product;
B, with A product insulation 10~50 minutes, filtering gained filtrate is the B product;
C, the B product are packed under 15~25 ℃ of temperature, placed 10~40 days in the sealed container, filter to get filtrate, obtain can long preservation earthworm liquid extraction.
The sterilizing methods of aforesaid earthworm liquid extraction, among the step a, disinfecting time can be 10~50 minutes.
The sterilizing methods of aforesaid earthworm liquid extraction, step b are preferably, with A product insulation 20~40 minutes, are the B product with 250~280 order stainless steel sift net filtration gained filtrates.
The sterilizing methods of aforesaid earthworm liquid extraction, step c is preferably, the B product are packed under 15~25 ℃ of temperature, placed 15~25 days in the sealed container, filter to get filtrate with 250~280 order stainless steel meshs then, obtain can long preservation earthworm liquid extraction.
Method of the present invention is through applicant's long term test, and screening obtains.The mashed garlic juice and the Lumbricus liquor factor have very strong complexation activation mechanism, make earthworm liquid extraction to reach the purpose of long preservation through keeping its biological activity after the high-temperature steam thorough disinfection sterilization.The present invention has earthworm liquid extraction is thoroughly sterilized, and keeps its bioactive characteristics, and the earthworm liquid extraction after handling through the present invention can be preserved more than 1 year, had improved storage life greatly.The invention solves the difficult problem that earthworm liquid extraction can not long preservation, the earthworm liquid extraction of handling through the present invention can add antiseptic and make various products, and long preservation is never degenerated.The present invention has created advantage for exploitation, the utilization of Lumbricus.The present invention also has active bio composition and the low characteristics of implementation cost do not destroyed.
The specific embodiment
Embodiments of the invention.By following step earthworm liquid extraction is carried out sterilization treatment:
A, 100 kilograms of fresh and alive Lumbricuss are handled by modes such as pulverizing, leaching or extractions, obtain the liquid extract of Lumbricus, get 10 kilograms of Bulbus Alliis to smash to pieces as mashed garlic juice, mashed garlic juice is added in the earthworm liquid extraction, the steam disinfection more than 100 ℃ of mixing, reuse, gains are the A product.
B, with A product insulation 30 minutes, be the B product with 280 order stainless steel sift net filtration gained filtrates.
C, the B product are packed in the sealed container after placing 20 days under 15~25 ℃ of temperature, filter to get filtrate with 280 order stainless steel meshs, obtain can long preservation the kind earthworm liquid extraction.
