The present invention has following technique effect:
The present invention does not add any chemical substance, environmental protection except adding enzyme.The present invention adopts two step enzyme cutting methods to extract collagen peptide from pigskin, has advantages of that Product Activity is high, yield is high.Aminopeptidase and carboxypeptidase are excision enzymes, the present invention at first adopts aminopeptidase and carboxypeptidase to carry out circumscribed to the collagen protein in the pigskin, other structural constituents of collagen protein and pigskin are separated, after making pigskin become loose shape, with endo-protease protein is carried out enzymolysis again and make protein become micromolecular protein peptide.Nearly all adopted go out for twice technique of enzyme of twice enzymolysis in the prior art, it is 201110315438.5 Chinese invention patent such as application number, the enzyme that goes out for twice all needs to improve temperature, then cooling, not only process trouble, and temperature is a very important factor in order for enzymic activity, and the control of temperature thing easily, therefore go out for the twice technological process operation easier of enzyme of twice enzymolysis is larger in the prior art, is unfavorable for the raising of production efficiency.And the present invention adopts two step enzymolysis, and the technique of the enzyme that once goes out has been saved the enzyme operation of going out, and effectively promoted production efficiency, and because enzyme of the present invention is chosen science, the yield of collagen peptide is also high than prior art.In the prior art, through behind the enzymolysis, the fat in the enzymolysis solution is particulate state; form suspension with enzymolysis solution, with centrifugal effect and not obvious, even delamination; and because fat particle is also remaining collagen protein being arranged, yield is very low, and the biologic activity of collagen peptide is also very low.And the present invention can thoroughly solve the problems of the technologies described above, behind the process enzymolysis second time, fat no longer is particulate state but becomes fat liquor, all fat almost all become liquid, by leaving standstill, fat liquor and enzymolysis solution are realized effective layering, and fat liquor swims on the enzymolysis solution, in this case, isolate enzymolysis solution and except degrease very convenient.Why adopt in the prior art enzyme that goes out for twice be because, be difficult to judge whether enzymolysis is complete for the first time, if enzymolysis is incomplete for the first time, the enzyme enzymolysis that the enzyme that adds so for the second time probably will add for the first time falls, the enzyme enzymolysis that the enzyme that perhaps adds is for the second time added for the first time, that is, there is the possibility of mutual enzymolysis between the different enzymes, causes the enzymolysis failure.And among the present invention, the enzyme that adds for the first time is aminopeptidase, carboxypeptidase and endo-protease, adopts aminopeptidase, carboxypeptidase and endo-protease that the collagen protein in the pigskin is carried out enzyme and cuts, when enzymolysis is complete, pigskin becomes loose shape, and namely other structural constituents of collagen protein and pigskin are separated.Add again the second enzyme this moment, the phenomenon of mutual enzymolysis between the different enzymes just can not occur.Therefore the present invention is achieved the technical scheme of the enzyme that do not go out in the two step enzymolysis process, and this technical scheme has significant technical progress with respect to prior art.
In sum, the present invention has scientifically chosen different proteolytic enzyme in different steps, has optimized processing step, has improved production efficiency, has promoted the yield of collagen peptide, has improved the activity of collagen peptide.The product that adopts the present invention to make, molecular weight account for approximately 90% between 500~2000 dalton, on average about 1000 dalton, active polypeptide content is up to more than 85%.
