Embodiment 1

[0061] Preparation of porcine hemoglobin solution: after blood collection from qualified pigs, add disodium edetate, sodium bicarbonate and tea polyphenols or apple polyphenols in a mass ratio of 1:5:0.03, of which ethylenediaminetetra The weight ratio of disodium acetate to pig blood is 2:1000. After mixing evenly, centrifuge for the first time at 25°C for 6 minutes to obtain the first supernatant layer and the first precipitate layer, and separate to obtain the first precipitate. 1. Add deionized water to the precipitate, and perform the first ultrasonic treatment for 60 seconds under the ultrasonic power of 2500W to obtain the porcine hemoglobin solution;

[0062] Pre-treatment: use nitrogen bubbling deoxygenation to carry out the first physical deoxygenation and preliminary decolorization of the porcine hemoglobin solution, then adjust the pH value of the deoxygenated porcine hemoglobin solution to 7, and then perform the second ultrasonic treatment under the ultrasonic pow...

Embodiment 2

[0074] Preparation of porcine hemoglobin solution: after blood collection from qualified pigs, add disodium edetate, sodium bicarbonate and tea polyphenols or apple polyphenols mixed in a mass ratio of 1:2:0.01, of which ethylenediaminetetra The weight ratio of disodium acetate to pig blood is 1:1000. After mixing evenly, centrifuge for the first time at 15°C for 3 minutes to obtain the first supernatant layer and the first precipitate layer, and separate to obtain the first precipitate. 1. Deionized water was added to the precipitate, and the first ultrasonic treatment was performed for 30 seconds under the ultrasonic power of 1800W to obtain a porcine hemoglobin solution;

[0075] Pre-treatment: Use nitrogen bubbling deoxygenation to perform the first physical deoxygenation and preliminary decolorization of the porcine hemoglobin solution, then adjust the pH value of the deoxygenated porcine hemoglobin solution to 6, and then perform the second ultrasonic treatment at 600W ul...

Embodiment 3

[0084] The preparation of porcine hemoglobin solution is specifically to collect blood from pigs that pass the inspection, and then add disodium ethylenediaminetetraacetate, sodium bicarbonate and plant phenols extracted from natural plants in a mass ratio of 1:3:0.03, of which ethylenediaminetetraacetate The weight ratio of disodium amine tetraacetate to pig blood is 1.5:1000. After mixing evenly, the first disc centrifugation is performed at 20°C for 4 minutes to obtain the first supernatant layer and the first precipitate layer, and the first precipitate is obtained by separation. Add 1.8-2 times the volume of deionized water to the first precipitate, and conduct the first ultrasonic treatment for 50 seconds under the ultrasonic power of 2000W to obtain a porcine hemoglobin solution.

[0085] Pre-treatment: use nitrogen bubbling deoxygenation to carry out the first physical deoxygenation and preliminary decolorization of the porcine hemoglobin solution, then adjust the pH va...

Abstract

The present invention relates to a pig blood treatment method, particularly to a pig blood extracting and using method, which comprises: preparing a pig blood hemoglobin solution, wherein an additive is added to pig blood, centrifuging separation is performed to obtain the first supernatant layer and the first precipitation layer, separating is performed to obtain the first precipitate, and a first ultrasonic wave treatment is performed; pre-treating, wherein physical deoxidation is performed, the pH value is adjusted, and a second ultrasonic wave treatment is performed; carrying out sectional enzymolysis decolorization; carrying out active carbon decoloration, wherein active carbon with the weight of 1-2% of the mass of the solution is added, and a decoloration treatment is performed for 5-10 min at a temperature of 25-35 DEG C; post-treating, wherein the pH value is adjusted, and centrifuging separation is performed to obtain the second supernatant layer and the second precipitation layer; taking the second supernatant layer, and carrying out ultra-filtration concentration separation to obtain the second concentrated solution; preparing pig blood plasma protein powder, wherein the first supernatant layer is subjected to spray-drying; preparing pig hemoglobin powder, wherein the second concentrated solution is subjected to spray-drying; and preparing a heme peptide, wherein the second precipitation layer substance is taken and is subjected to roller drying. The method of the present invention has the good decolorization effect, and the product with the high protein content and the low ash content can be prepared.

Description

technical field [0001] The invention relates to a method for processing pig blood, in particular to a method for extracting and utilizing pig blood. Background technique [0002] The protein content of red blood cells in pig blood is as high as 38%, accounting for more than 75% of the total protein in whole blood, of which more than 92% is hemoglobin, so pig blood cells are an excellent source of animal protein. Made into blood cell powder for sale. But because the blood cell powder contains heme, the blood cell powder is black and red, and has a heavy bloody smell, which is unacceptable to the sense organs, and its economic added value is not high. [0003] Heme is in the form of porphyrin iron combined with four globins to form hemoglobin, which exists in red blood cells. In the food industry, heme can replace the chromogen nitrate and artificial pigments in meat products, and the use of heme can reduce the carcinogenic effect of nitrite. In the pharmaceutical industry,...
