Description
Technical field
The present invention relates to defatting technology field, the degreasing method of especially a kind of animal tissue and its application.
Background technique
Currently, the degreasing method of animal tissue includes the methods of chemical immersion extracting and supercritical fluid extraction.Chemistry leaching
Bubble extracting mainly use lye (such as sodium hydrate aqueous solution, by with fat occur saponification), organic reagent (such as acetone,
The organic reagents such as petroleum ether, ethyl acetate, are extracted by similar compatibility principle) etc..Chemical method degreasing is general time-consuming long, chemistry examination
Agent dosage is big, pollutes environment, and reagent easily remains in animal tissue.
Supercritical fluid extraction is to utilize some substances (such as carbon dioxide, water, nitrous oxide) in the supercritical state
, the characteristics such as density big small with viscosity, have many advantages, such as that dissolubility is strong, diffusivity is good, easily controllable, pass through control temperature and pressure
Extraction and separation of the supercritical fluid to fat can be realized in power, efficiently can thoroughly slough the objects such as the fat in animal tissue
Matter.Meanwhile supercritical carbon dioxide extracting is low with supercritical temperature, cleaning noresidue, carbon dioxide source is wide, cheap easy
, it is safe and non-toxic, non-ignitable the advantages that, have a extensive future.But supercritical fluid extraction the high requirements on the equipment, overcritical item
The maintenance energy consumption of part needs to consider with safety.
Common animal tissue virus inactivating method is mostly that strong acid and strong base solution is handled, ion irradiation radiation treatment etc., but
These methods will cause chemical bond rupture so as to cause the decrease of mechanical strength, and to animal tissue to animal tissue itself
Excess processes will lead to albuminous degeneration, influence the application effect etc. of material in vivo.
Summary of the invention
Based on the above issues, a kind of animal is provided it is an object of the invention to overcome above-mentioned the deficiencies in the prior art place
The degreasing method of tissue, this method degreasing rate can reach 99% or more, while can remove potential virus in animal tissue, removal rate
99% or more can be reached；Meanwhile without chemical agent residue in organizing after this method degreasing, the mechanics that will not weaken animal tissue is strong
Degree, not will lead to protein denaturation in animal tissue.
To achieve the above object, the technical scheme adopted by the invention is as follows: a kind of degreasing method of animal tissue, including as follows
Step:
