Embodiment 1
[0026] The original blood is fresh pig blood within 10 minutes of slaughtering and bleeding.
[0027] A kind of preparation method of the livestock and poultry plasma protein powder that takes fresh pig blood as raw material comprises the following steps (see figure 1 ):
[0028] (1) According to the mass concentration of 6-8% of sodium citrate, 3-4% of dipotassium EDTA and 3-4% of sodium hexametaphosphate, the compound anticoagulant aqueous solution (compound anticoagulant solution for short); The volume ratio of blood to compound anticoagulant aqueous solution is 1 / 19 (V / V), add compound anticoagulant solution to fresh pig blood, and stir and mix in time to realize anticoagulant treatment of pig blood; input the obtained anticoagulant pig blood Store in a sealed tank at 4-15°C for later use, and the tank storage time is ≤20h.
[0029] (2) Under the environment of 4-15°C, the anticoagulated pig blood is pumped into a tubular centrifuge to separate blood cell fluid and plasm...
Embodiment 2
[0034] Raw materials: fresh cattle blood slaughtered and bled within 10 minutes.
[0035] Other conditions are with embodiment 1. The product is bovine blood plasma protein powder.
Embodiment 3
[0037] Raw materials: fresh chicken blood slaughtered and bled within 10 minutes.
[0038] Method: except that the spray drying air inlet temperature is 200°C-220°C and the exhaust air temperature is 100-110°C, other conditions are the same as in Example 1. The product is chicken blood plasma protein powder.
