(A1) crushing sturgeon fishbone raw materials, and sieving the crushed sturgeon fishbone raw materials with a sieve of 160-300 meshes to obtain fishbone powder; experiments show that the crushing fineness of the fishbone raw material influences the overall effect of the extraction process, the polypeptide activity of the finally obtained product is poor due to the excessively fine fineness, the enzymolysis is incomplete due to the excessively coarse fineness, the dissolution rate and the absorption rate of the organic selenium and the molecular weight of the peptide after enzymolysis are large, and the overall nutritive value is reduced.
(A2) Performing first enzymolysis on the fishbone powder obtained in the step (A1), degrading a fishbone collagen skeleton, and exposing the selenoglycoprotein to obtain an enzymolysis crude product;
the method comprises the following specific steps:
adding water into the fishbone powder obtained in the step (A1) according to a solid-to-liquid ratio (mass ratio) of 1: 1-1: 2 to prepare a suspension, adding collagenase and cellulase for enzymolysis, wherein the mass of the collagenase is 0.3-0.5% of the mass of the fishbone powder, the mass of the cellulase is 0.1-0.4% of the mass of the fishbone powder, and the enzymolysis is carried out for 0.5-1.5 hours while continuously stirring and maintaining the temperature at 25-30 ℃; heating to above 90 deg.C, and maintaining for 30min to inactivate enzyme.
(A3) And (D) carrying out second enzymolysis on the enzymolysis crude product obtained in the step (A2) to obtain an enzymolysis refined product, so that the selenoglycoprotein is degraded into small molecular polypeptide, wherein the mass proportion of the polypeptide with the molecular weight of less than 250Da exceeds 80%, and the small molecular polypeptide becomes the selenium-enriched polypeptide, thereby improving the absorptivity of selenium element.
The method comprises the following specific steps:

Meanwhile, the enzyme digestion result also determines the absorption and utilization degree of the selenium element, and the anti-aging activity difference of different selenium-containing peptide fragments is obvious. Therefore, the selection of the mixed protease and the corresponding enzymolysis conditions are unpredictable, and even if the mixed protease is the same protease, the enzyme conformation is changed due to the difference of enzymolysis environments, including the difference of the pH value of an enzymolysis system and the polarity of a solvent, so that the specific enzyme cutting site is uncertain. According to the preferable scheme, the subtilisin, the pancreatin and the bromelain are mixed according to the mass ratio of 1: 1-2.5: 0.8-1.2 for mixed enzymolysis, the polyethylene glycol is added to change the polarity of the solution and the solid-liquid contact surface, and the content of polypeptide with the enzymolysis product being less than 243 daltons is more than 80% and has excellent activity.

Through statistical treatment, compared with a normal control group, the anti-fatigue capability of mice in a kidney-yang deficiency syndrome model group given hydrocortisone is remarkably reduced; the intragastric base liquor 1 and the base liquor 2 of the mice of the kidney-yang deficiency model group and the commercially available Feitian Maotai have no obvious difference compared with the mice of the kidney-yang deficiency model group; the sturgeon bone peptide wine prepared in the gastric perfusion examples 1 to 3 can effectively enhance the fatigue resistance of mice with yang deficiency syndrome, and compared with a model group with yang deficiency syndrome, the sturgeon bone peptide wine group has very obvious difference, wherein the sturgeon bone peptide wine prepared in the example 2 is best modified, and has more obvious fatigue enhancement effect compared with the sturgeon bone peptide wine prepared in the examples 1 and 3.
3.3 Cold resistance test:
after 30min of the last administration, each group of mice was placed in a refrigerator at-18 ℃, and the number of deaths of the animals was observed after 60min, and the experimental results are shown in the following table:
influence of sturgeon bone peptide wine on cold resistance of mice with syndrome of kidney yang deficiency
X2The test was △ P < 0.05 compared to the normal control group.
It can be seen from the above table that, in the model of kidney-yang deficiency caused by hydrocortisone, the cold tolerance of the mice is obviously reduced, the cold tolerance of the mice with kidney-yang deficiency cannot be improved by the intragastric base liquor (including Feitian Maotai), and the cold tolerance of the mice with kidney-yang deficiency can be improved after the sturgeon bone peptide liquor is taken. Warp X2The test shows that the sturgeon bone peptide wine group has significant difference with the kidney-yang deficiency model group.
3.4 Effect on the weight of the immune organs of mice with syndrome of Experimental Kidney Yang deficiency
40 Kunming male mice with the age of 10-12 months and the weight of 50g +/-3 g are grouped and administered as above. After giving the wine half an hour on day 5, the spleen and thymus of the mice were then picked and weighed, and thymus (mg)/body weight (10g) and spleen (mg)/body weight (10g) were calculated and t-test was performed between groups. The results are detailed in the following table:
influence of sturgeon bone peptide wine on weight of immune organs of experimental kidney-yang deficiency mice
In the sturgeon bone peptide wine gavage experiment of example 2, the spleen dissection process is shown in fig. 5, and the thymus weighing process is shown in fig. 6.
