[0032] This embodiment also provides a preparation method of the above composition, which includes:
[0033] Step S1: extracting the mixture composed of natto and germinated soybeans with a buffer solution with a pH value of 4-5 to obtain an extract.
[0034] Natto is a soy product made from soybeans fermented by Bacillus natto (Bacillus subtilis). It is sticky, smells bad, and tastes slightly sweet. During the fermentation process, it produces a variety of physiologically active substances, including nattokinase .
[0035] Germinated soybeans refer to mature soybeans that germinate under suitable conditions. The germinated soybeans are rich in polypeptides as shown in SEQ ID NO: 1-4.
[0036] Preferably, when preparing the extract, the mixture of natto and germinated soybeans is mashed or ground to increase the dissolution rate of nattokinase and the polypeptide shown in SEQ ID NO: 1-4, thereby improving the extraction efficiency.
[0037] Further, the extraction temperatur...
Embodiment 1
[0050] The present embodiment provides a kind of composition, it comprises:
[0051] (1) The polypeptide shown in SEQ ID NO:1;
[0052] (2) Nattokinase.
[0053] The preparation method of this composition comprises:
[0054] a. Mix natto and germinated soybeans at a mass ratio of 1:1, mash them, mix them with a buffer solution with a pH value of 4 at a solid-to-liquid ratio of 1:5, and stir and extract at 15°C for 10 hours to obtain an extract.
[0055] b. Filtrate the extract with a microfiltration membrane with a molecular weight cut-off greater than 3000Da to obtain the filtrate;
[0056] c. Mix the obtained filtrate and table salt according to the mass volume ratio of 320g / L, then carry out salting-out at 15°C to obtain the salt-out product, and then use gel filtration or particle exchange to remove the salt in the salt-out product, After lyophilization, the composition is obtained.
Embodiment 2
[0058] The present embodiment provides a kind of composition, it comprises:
[0059] (1) the polypeptide shown in SEQ ID NO:2 and SEQ ID NO:3;
[0060] (2) Nattokinase.
[0061] The preparation method of this composition comprises:
[0062] a. Mix natto and germinated soybeans at a mass ratio of 1:2, mash them, mix them with a buffer solution with a pH value of 4 at a solid-to-liquid ratio of 1:4, stir and extract at 8°C for 12 hours to obtain an extract.
[0063] b. Filtrate the extract with a microfiltration membrane with a molecular weight cut-off greater than 3000Da to obtain the filtrate;
[0064] c. Mix the obtained filtrate and table salt according to the mass volume ratio of 380g / L, then carry out salting-out at 8°C to obtain the salt-out product, and then use gel filtration or particle exchange to remove the salt in the salt-out product, After lyophilization, the composition is obtained.
