| titleOfInvention | Heme extraction method |
| abstract | The invention discloses a heme extraction method, which comprises the following steps: (1) centrifuging the anticoagulated pig blood, collecting erythrocyte liquid, mixing the erythrocyte liquid with water, stirring for hemolysis, then adjusting the pH value to 7-9, and adding compound proteolytic enzyme for enzymolysis; (2) adjusting the pH value of the enzymatic hydrolysate to 3-3.5 after enzymolysis, and collecting a first precipitate after standing; (3) dissolving the first precipitate in a sodium hydroxide solution, adjusting the pH value to 7-9, centrifuging to obtain a supernatant, adding anhydrous calcium chloride into the supernatant to precipitate heme, centrifuging and collecting a second precipitate; (4) washing the second precipitate to neutrality, and collecting a third precipitate; (5) and drying the third precipitate to obtain the product. The heme prepared by the method has high yield and high purity, and the heme extraction method has the advantages of low cost, high preparation efficiency, safety, environmental protection, simple and controllable production process, good economic and social benefits and very optimistic market prospect. |
