Embodiment 1-7

[0052] Preparation of plasma protein powder

[0053] Whole blood from healthy pigs was collected, anticoagulated with 4% trisodium citrate, and the anticoagulated whole blood was separated into heavy liquid and light liquid by using a tubular continuous separator. The heavy liquid was blood cell liquid, and the light liquid was plasma. The separation factor It is 4:6.

[0054] The plasma was homogenized with a high-pressure homogenizer (model GYB3022 purchased from Shanghai Donghua Homogenizer Factory). The applied pressure is shown in Table 1.

[0055] The plasma was sprayed dry with a high-speed centrifugal spray dryer (produced by Heilongjiang Dairy Machinery Factory), the air inlet temperature was 160° C., and the outlet air temperature was 68° C. to obtain off-white plasma protein powder.

Embodiment 8-14

[0059] Preparation of Hemoglobin Powder

[0060] Whole blood from healthy pigs was collected (purchased from the slaughterhouse of Shanghai Wufeng Shangshi Group), anticoagulated with 4% trisodium citrate, and separated into two parts, heavy liquid and light liquid, by a tubular continuous separator. The heavy liquid is blood cell fluid, the light liquid is plasma, and the separation factor is 4:6.

[0061] The plasma was homogenized with a high-pressure homogenizer (model GYB3022 purchased from Shanghai Donghua Homogenizer Factory). The applied pressure is shown in Table 2.

[0062] The plasma was sprayed dry with a high-speed centrifugal spray dryer (manufactured by Heilongjiang Dairy Machinery Factory), the air inlet temperature was 160° C., and the outlet air temperature was 68° C. to obtain dark brown hemoglobin powder.

Embodiment 15

[0066] Bactericidal efficacy test:

[0067] Mix a certain amount of Escherichia coli bacteria liquid into the fresh plasma, divide it into eight parts, seven of them, and process the feed liquid through a small high-pressure homogenizer (pressure 50MPa, 60MPa, 70MPa, 90MPa, 110MPa, 120MPa, 130MPa), and then Plasma protein powder (test group) was spray-dried by small spray drying equipment (inlet air temperature 160°C, outlet air temperature 68°C). The other group was directly spray-dried into plasma protein powder (control group) by small spray drying equipment (inlet air temperature 160°C, outlet air temperature 68°C).

[0068] Detection method: according to the national food microbiology detection standard (GB4789) to detect coliform bacteria.

Abstract

The invention discloses a blood plasma albumen and / or blood corpuscle albumen preparing method, which adopts a high pressure homogenizing machine to dispose the fresh animal blood plasma and / or blood corpuscle under the pressure of 60 to 120 MPa and mechanically sterilize the pathogen microbe and lead to the fresh blood corpuscle cell membrane breaking. The generated blood plasma albumen powder and / or blood corpuscle albumen powder have high security and greatly improve the digestion and absorption rate.

Description

technical field [0001] The invention relates to a method for processing animal blood, in particular to a method for preparing animal-derived protein feed raw materials. Background technique [0002] High-quality World Food and Agriculture Organization estimates that the world currently lacks 25 million tons of protein feed every year, and our country lacks 2 million tons every year. Fish meal and bone meal are the main sources of high-quality animal protein. my country imports an average of 1 million tons of fish meal and 400,000 tons of meat and bone meal from abroad every year. High-end feed materials such as plasma protein powder and intestinal membrane protein powder rely on imports for a long time. Due to the decline of marine catches and the periodic prohibition of supplementary fishing, the output of fishmeal as the main animal-derived protein raw material has been declining year by year, and animal-derived protein feed resources are generally scarce, which has become...
