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.

Abstract

The invention relates to a method for preparing animal blood plasma albumen powder, which comprises a process system consisting of animal blood anticoagulant treatment, blood refrigeration, centrifugal separation, membrane concentration, spray drying and tail gas recycling. The method comprises the following steps of: performing anticoagulant treatment on the fresh animal blood with a compound anticoagulant liquid, refrigerating, performing centrifugal separation on the refrigerated product and obtaining blood plasma liquid; performing membrane concentration on the blood plasma liquid, allowing the obtained product to flow to a tail gas recycling device for spray drying, and absorbing blood plasma albumen powder and afterheat in the dry tail gas; performing micropore filtration and spray drying, and obtaining the high-quality animal blood plasma albumen powder. Waste gas generated by the treatment of the tail gas recycling device is directly discharged into the air. The process method reduces the ash content of the animal blood plasma albumen powder from 12 percent to 8 percent, removes odor and increases the spray drying recovery rate from 98 percent to 99.5 percent, so that resources are saved, drying energy consumption is reduced, and the risks of polluting environment are reduced.

Description

technical field [0001] The invention belongs to the technical field of processing and utilization of livestock and poultry blood, and in particular relates to a method for preparing livestock and poultry plasma protein powder by using livestock and poultry blood. Background technique [0002] Livestock blood is the main by-product of the meat slaughtering and processing industry. It is rich in protein, minerals, active peptides and other nutrients and active ingredients. It is known as "liquid meat". However, the level of processing and utilization of livestock and poultry blood in our country is very low, and even causes serious environmental pollution, which needs to be developed urgently. If it is separated and dried, various high value-added products such as food, feed additives, and biochemical products can be produced. Plasma protein powder is a powder product processed from the plasma of livestock, poultry and other animals. It is rich in protein, trace elements and ...
