Description

The extracting method of carnosine
Technical field
The present invention relates to the production technique of medication chemistry, specifically from animals skeletal muscle, extract the method for carnosine.
Background technology
Carnosine is a kind of natural dipeptides, is present in the muscle, is made up of Beta-alanine and Histidine.Boldyrev report carnosines such as (1988) has antioxygenation, can suppress the fats oxidn reaction that is caused by iron, copper, myohaemoglobin and lipoxidase.Carnosine has the antioxygenation stronger than BHA, BHT, TBHQ, PG and alpha-tocopherol.Decker etc. (1990) discover that also carnosine can suppress in the body by iron, reduced hematin, lipoxidase and the catalytic oxidizing reaction of simple substance oxygen.Carnosine can also suppress the formation and the change in color of rancid flavor, the sample that adds carnosine is after storage 1 month, its rancid flavor significantly is lower than the sample that adds BHT, alpha-tocopherol and tripoly phosphate sodium STPP, and it to protect chromatic effect better than BHT, alpha-tocopherol and tripoly phosphate sodium STPP, BHT, alpha-tocopherol and tripoly phosphate sodium STPP are invalid (Decker etc., 1991 to the protection color; 1995).The shrimps that add carnosine are after storage 45 days, and its shrimp shell color, taste etc. are no change substantially.Carnosine is widely used in fields such as pharmaceutical adjuvant, foodstuff additive, makeup and fodder additives at present, is a kind of natural antioxidants, colour protecting agent of high-efficiency low-toxicity.
The preparation method of existing carnosine gets (F.J.Vinicket al. for utilizing chemical synthesis process, J.Org.Chem.1983,48 (3), 392 etc.), its shortcoming is to use a large amount of organic chemistry solvents: hydrazine compound, sulfide etc. is the chemical substance of severe toxicity, and triazo-compound is inflammable and explosive chemical, produce in must be between hoolivan, troublesome poeration, contaminate environment, infringement HUMAN HEALTH; And facility investment is big, and production efficiency is low, and the production cycle is long, the production cost height.
Summary of the invention
At the harm of existing carnosine preparation method existence and the problem that production efficiency is low, production cost is high, the object of the invention is to provide a kind of production technique of extracting carnosine from animals skeletal muscle.
The present invention adopts following technical solution:
(1) gets fresh or frozen healthy animal meat, remove non-muscle groups fabric, clean, drain with water for injection;
(2) be twisted into fragment with mincer earlier, levigate with colloidal mill, collect homogenate, add water for injection and stir evenly into slurries;
(3) slurries are heated to 42 ℃~45 ℃, transfer pH to 1.5~1.7, add stomach en-, or aspartic protease or papain, after stirring evenly, keep the condition hydrolysis of pH1.5~1.7,42 ℃~45 ℃ with acid;
(4) transfer pH to 7.5~7.7 with the slurries of alkali after with hydrolysis, add then after pancreatin or Sumizyme MP stir evenly, maintain 7.5~7.7,42 ℃~45 ℃ hydrolysis of pH, enzymolysis finishes post-heating and is warming up to 100 ℃, be incubated 5~15 minutes and carry out enzyme-deactivating, be cooled to below 30 ℃;
(5) transfer pH to 2.8~3.0, standing over night with acid;
(6) carry out solid-liquid separation, isolated clear liquid is with adjusting PH with base to 6.8~7.0, and is standby;
(7) with water for injection hydroxyapatite furnishing pasty state is adorned post, use the superphosphate buffer solution for cleaning behind the dress post, use acid phosphatase salt buffer balance again, hydroxyapatite chromatography post on the above-mentioned filtrate is adsorbed, use the superphosphate buffer solution elution;
(8) collect target compound, carry out ultrafiltration, collect filtrate, carnosine stoste is carried out spraying drying, collect xeraphium with filter membrane;
(9) microbial limit, assay, acidity detection are carried out in sampling.
Described animal meat can be beef, rabbit meat, chicken, the flesh of fish, mutton or pork etc.
The alkali that described adjust pH is used can be sodium hydroxide, calcium hydroxide, potassium hydroxide, sodium bicarbonate or ammoniacal liquor etc.
The acid that described adjust pH is used can be hydrochloric acid, phosphoric acid, citric acid, sulfuric acid etc.
With the process that enzyme is hydrolyzed, can grasp the hydrolysis process by the control hydrolysis time, hydrolysis time is short, and the insufficient yield that causes of hydrolysis is low, can extend manufacture cycle again but hydrolysis time is long, increases production cost.Hydrolysis time can be 420~540 minutes in the general step (3).Equally, hydrolysis time is 120~240 minutes in the described step (4).
Described acid phosphatase salt buffer can be 10~30mmol/L pH5.8~6.8 phosphate buffered saline buffers.
For guaranteeing drying effect, described centrifugal spray drier feeding temperature can be made as 45 ℃, and out temperature can be 140 ℃~70 ℃, atomizer rotating speed 8000r/min.
It is the ultra-filtration membrane of 3~8KD that described ultrafiltration can be adopted molecular weight cut-off.
The present invention is hydrolyzed into micromolecule polypeptide by animals skeletal muscle is carried out double-enzyme hydrolysis with macro-molecular protein, uses hydroxyapatite chromatography post absorption and purification then, can Fractional Collections obtains single, purity than higher carnosine.This method is compared with synthetic method, has following advantage:
1, do not use severe toxicity, inflammable and explosive chemical such as hydrazine compound, sulfide, triazo-compound, fresh or frozen animal meat is directly extracted carnosine through production technique such as two enzyme enzymolysis, the tool safety non-pollution, less put into production equipment, reduce advantages such as production link.
2, double-enzyme hydrolysis muscle tissue homogenate adopt to extract, the centrifugal acquisition supernatant liquor of residue, after filtration, go up hydroxyapatite chromatography post absorption and purification, production technique such as ultrafiltration, hydrolysis is complete, can remove foreigh protein removing and macromole impurity, reaches good separating effect.
3, adopt two enzyme enzymolysis, extraction, the centrifugal acquisition supernatant liquor of residue, after filtration, go up hydroxyapatite chromatography post absorption and purification, production technique such as ultrafiltration, advantage be shorten greatly in production stage, cycle, yield improves, production cost reduces, production environment requires to reduce, easy and simple to handle, reduced medicine and be subjected to microbial contamination, rotten chance.
4, adopt centrifugal spray drying, can obtain faint yellow powdered granule, uniform particles, no brown impurity solvability is good.
5, preparation is simple, and raw material is easy to get, the reaction conditions gentleness, and the yield height, good stability, and also the cycle is short, and also very low to preparation equipment and place requirement, be suitable for large-scale industrial production.
