Technical field
The present invention relates to a kind of methods making high-calcium type animal amino acid using marine shellfish.
Background technology
The shell stock number of marine shellfish is very big, is concentrated mainly on marine shellfish culture zone and the marine products of coastal area
Shellfish culture enterprise.Main abandoned piles in seashore or are abandoned to neritic province domain before, form seabed to a certain extent
Attachment base, to halobios have positive effect.But in recent years, the shellfish processing method of mechanization causes in seashell
Considerable amount of shellfish meat is remained, local water pollution is caused.And China's environmental bearing capacity progressively reaches the limit, national ring in recent years
It protects supervise and examine to put more effort, traditional animal amino acid is mainly using animal hair, animal skeleton as raw material, by chemistry or enzymolysis
Technique obtains or of poor quality and environmental pollution is big or cost is high, and causes the source of goods short.The animal of high-calcium type
Amino acid is especially short, since divalent calcium ions have chelating inhibiting effect to general protease, has wadding to amino acid solution
Solidifying effect, so chelating calcium amino acid is a kind of novel and very popular product.
Invention content
The purpose of the present invention is processing discarded a large amount of shells and subsidiary shellfish meat using marine shellfish, it is used cooperatively weak acid
Acidolysis, carbon dioxide absorption, lye recycling, protein digestion, de-oiling fat, enzyme deactivation are lived, in no pollution discharge
On the basis of realize less salt amount amino acid solution output, to produce the side of high quality calcium carbonate and high-calcium type animal amino acid
Method.
For achieving the above object, the technical solution adopted by the present invention is：It is a kind of to make high-calcium type using marine shellfish
The method of animal amino acid, which is characterized in that this method includes the following steps：
1）Shelling：The discarded seashell of accumulation and meat are positioned in the reaction kettle of sealing, water, acetic acid is added, adjusts pH value
Meat shell separation is carried out, in separation process, generates carbon dioxide gas, generates with calcium acetate solution and swims in shell on solution
Meat；
2）By step 1）The carbon dioxide gas of generation is absorbed using sodium hydroxide or potassium hydroxide solution, generates sodium carbonate
Or potassium carbonate；
3）Separation：Shell meat in reaction kettle is detached with calcium acetate solution, shell meat is put into enzymatic vessel；
4）Calcium carbonate output：By after step 2) absorbing carbon dioxide gas sodium hydroxide or potassium hydroxide solution and calcium acetate it is molten
Liquid mixes, and reacted formation precipitation, sediment is calcium carbonate, and solution is sodium acetate or potassium acetate solution；
5）Enzymolysis：By step 4）The sodium acetate or potassium acetate solution of middle generation are pumped into step 3）Enzymatic vessel in, adjust pH8-10,
Alkali protease 2 ‰ -1% is added, is warming up to 45-65 DEG C and opens stirring, digests 6-12h, the grease during this in shellfish meat
It is decomposed into glycerine and fatty acid salt under alkaline condition；
6）Inactivation：After the completion of enzymolysis, 80 DEG C are warming up to, stirring 10-30min inactivations are high-calcium type animal amino acid after cooling.
Preferably, step 1）In, the addition of water is the 1/3-1/2 of raw material weight, and the addition of acetic acid is water weight
1-3%。
Preferably, step 2）In, suitable alkali is added in sodium hydroxide or potassium hydroxide solution, ensures the pH value dimension of solution
It holds 9 or more.
Preferably, step 5）In, alkali protease is calpain.
Preferably, further include step 7）, step 7）By step 6）The high-calcium type animal amino acid solution of generation is using concentration
And pulvis is made in spray drying process.
This method makes full use of the natural resources, fiting chemical and biological enzyme, and no pollution discharges output high level aminoacids solution
Two kinds of products of body and high quality calcium carbonate.The animal amino acid chelates those high in calcium ion, and salt content is not high, according to using
Lye metal ion it is different, can be applied to the fields such as feed, fertilizer.
Description of the drawings
Attached drawing 1 is the production flow diagram that high-calcium type animal amino acid is carried out by taking oyster shell meat as an example.
Specific implementation mode
Method provided by the present invention is described in detail with reference to the accompanying drawings and embodiments.
It is illustrated by taking the shell meat of oyster as an example in the present embodiment.
As shown in Fig. 1, in the present embodiment, the production method of high-calcium type animal amino acid is carried out such as using oyster shell meat
Under：
1）Shelling
Discarded oyster shell 10t is placed in shelling pond, sealing cover is covered, aqueous is added to seal, exhaust gas collecting pipe is placed in collecting tank liquid
At 2/3 below face, add water 5t, be slowly added to industrial acetic 50kg, acetic acid is slowly added in 30 minutes, and acetic acid is added altogether
Shelling is basically completed after 50Kg, 1h；
2）Tail gas absorption
Tail gas absorption liquid uses sodium hydroxide, and concentration of sodium hydroxide solution 20%, after the completion of absorption, tail gas absorption liquid is muddiness
Liquid, pH are 10.3 or so, and pH value in order to control, can be added suitable alkali in sodium hydroxide solution in the process；
3）Separation
To shell the scallop in pond and dejacketing solution separation, using 2 mesh nylon leaching nets, obtain oyster meat about 300kg, shelling water
14.5 ton or so；
4）Calcium carbonate output
Dejacketing solution is poured into tail gas absorption liquid in cement sedimentation basin and is mixed, precipitation of calcium carbonate is gradually formed, supernatant is sodium acetate
Solution；
