Abstract
The present invention relates to a kind of manufacture craft of soluble chitin, completed by the steps：(1) shrimp shell or crab shell are equipped with, and is eluted with water and dries；(2) clean shrimp shell or crab shell are dipped in 6%~8% watery hydrochloric acid and mixed thoroughly；(3) shrimp shell after acid treatment or crab shell are put and clear water and 8%~10% sodium hydroxide is added in people's pot, boiled；(4) shrimp shell or crab shell for treating above-mentioned soda acid, adds water and adds liquor potassic permanganate, except depigmentaton, is then washed with water net；(5) by the shrimp shell or crab shell after decolouring, pressure removes moisture, spread out dry insoluble chitin；(6) insoluble chitin is placed in jacketed pan, adds 40% soda bath, mix thoroughly, kept for 24 hours at a temperature of 60~65 DEG C.The beneficial effects of the invention are as follows：Not only extraction process is simple, chitin recovery rate is high, and the chitin purity extracted is high, good brightness.
Description
Technical field
The present invention relates to medicine manufacturing field, and in particular to a kind of manufacture craft of soluble chitin.
Background technology
Chitin is chitosan (chitosan), is that the chitin (chi t in) being widely present by nature passes through de- second
Acyl acts on what is obtained, and chemical name is Chitosan (1-4) -2- amino-B-D glucose, from 1859, Frenchman Rouget
After obtaining chitosan first, the biological functionality and compatibility of this natural polymer, blood compatibility, security, microorganism
The premium properties such as degradability by all trades and professions extensive concern, medicine, food, chemical industry, cosmetics, water process, METAL EXTRACTION and
The application study of the numerous areas such as recovery, biochemical and biomedical engineering achieves major progress.For patient, chitosan drop blood
Fat, the existing research report of hypoglycemic effect.
The content of the invention
In summary, the technical problems to be solved by the invention are to provide a kind of manufacture craft of soluble chitin.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of manufacture craft of soluble chitin, by such as
Under step complete：
(1) shrimp shell or crab shell are equipped with, and is eluted with water and dries；
(2) clean shrimp shell or crab shell are dipped in 6%~8% watery hydrochloric acid and mixed thoroughly, shrimp shell or crab shell must not be exposed, warp
28~48 hours, when bubble no longer produces are spent, cleans shrimp shell or crab shell repeatedly with clear water, until the wash water determined when pH test paper is in
Untill neutrality；
(3) shrimp shell after acid treatment or crab shell are put and clear water and 8%~10% sodium hydroxide is added in people's pot, boiling makes
Protein, fat are completely dissolved, and shrimp shell or crab shell is then washed with water, untill wash water is in neutrality；
(4) shrimp shell or crab shell for treating above-mentioned soda acid, adds water and adds liquor potassic permanganate, except depigmentaton, then
It is washed with water net；
(5) by the shrimp shell or crab shell after decolouring, pressure removes moisture, spread out dry insoluble chitin；
(6) insoluble chitin is placed in jacketed pan, adds 40% soda bath, mix thoroughly, at a temperature of 60~65 DEG C
Kept for 24 hours, and timing agitation；When shell can dissolve in the dissolving of 1% glacial acetic acid, it is in neutrality that taking-up, which is washed with water, after drying,
Obtain soluble chitin.
Further, shrimp shell or crab shell and the weight of watery hydrochloric acid ratio are 1 in step (2)：1.5.
Further, boiled 1.5 hours in step (3).
The beneficial effects of the invention are as follows：Not only extraction process is simple, chitin recovery rate is high, and the chitin extracted is pure
Degree is high, good brightness.
Embodiment
The principle and feature of the present invention are described below in conjunction with instantiation, example is served only for explaining this hair
It is bright, it is not intended to limit the scope of the present invention.
(1) raw material.Shrimp shell or crab shell, are eluted with water.When needing storage as do not processed in a short time, it is necessary to clean and store after drying
Hide.
(2) pickling.Net shell is dipped in 6%~8% watery hydrochloric acid to (ratio of shell and watery hydrochloric acid is 1：1.5) mix thoroughly, shell
It must not expose.By 28~48 hours, when bubble no longer produces, shell softening, illustrate that calcium carbonate all dissolves.With clear water repeatedly
Clean (with except the interior impurity that shells) when the wash water of pH test paper measure is in neutral, show that cleaning is completed.
(3) caustic dip boils.Soft shell after acid treatment is put clear water and 8%~10% sodium hydroxide are added in people's pot, boiled
About 1.5 hours, protein, fat are completely dissolved, is then washed with water, until wash water is in neutrality.
(4) oxidative decoloration.The shell that above-mentioned soda acid is handled, add water and add appropriate liquor potassic permanganate, except depigmentaton, so
After be eluted with water.
(5) dry.By the shrimp shell or crab shell after decolouring, pressure removes moisture, spreads out and dry.Insoluble chitin.
(6) deacetylation.Insoluble chitin is placed in jacketed pan, 40% soda bath is added, mixes thoroughly, 60~65
Kept for 24 hours at a temperature of DEG C, and timing agitation.When shell can dissolve in the dissolving of 1% glacial acetic acid, illustrate that deacetylation is complete
Into.Taking-up is washed with water in neutrality, after drying, obtains soluble chitin (or chitosan).
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
