Problems solved by technology

At present, the existing deodorization technologies are mainly acid and alkali soaking deodorization, high temperature vacuum deodorization and physical adsorption deodorization such as activated carbon. In addition, flavor additives such as fruit powder and protein powder are mixed to solve the problem of fishy smell. It cannot completely solve the problem of the smell of plasma protein powder, and it will also cause nutritional loss to plasma protein

Embodiment 1

[0038] A kind of preparation operation step of brewing blood plasma protein powder is as follows:

[0039] (1) Vacuum blood collection

[0040] Vacuum blood collection equipment is used to collect blood from quarantined pigs, and the collected pig blood is placed in a closed and clean storage tank.

[0041] (2) Blood anticoagulation

[0042] Sodium citrate anticoagulant was added to the collected pig blood. The amount of anticoagulant added was 3% of the pig blood mass, and it was stored at 4°C to obtain anticoagulant blood.

[0043] (3) Centrifugal separation

[0044] The anticoagulated blood was placed in a high-speed tube centrifuge for centrifugation at a speed of 12,000 rpm, and the separated plasma was stored at 4°C.

[0045] (4) step-by-step enzymatic release of fishy smell

[0046] Add 3 mol of pancreatic lipase (the amount of pancreatic lipase added is 30mmol / Kg) to 100Kg of separated plasma liquid, enzymolyze at 30°C for 20min, and then add 8 mol of neutral prote...

Embodiment 2

[0060] A kind of preparation operation step of brewing blood plasma protein powder is as follows:

[0061] (1) Vacuum blood collection

[0062] Vacuum blood collection equipment is used to collect blood from quarantined pigs, and the collected pig blood is placed in a closed and clean storage tank.

[0063] (2) Blood anticoagulation

[0064] Sodium citrate anticoagulant was added to the collected pig blood. The amount of anticoagulant added was 3% of the pig blood mass, and it was stored at 4°C to obtain anticoagulant blood.

[0065] (3) Centrifugal separation

[0066] The anticoagulated blood was placed in a high-speed tube centrifuge for centrifugation at a speed of 12,000 rpm, and the separated plasma was stored at 4°C.

[0067] (4) step-by-step enzymatic release of fishy smell

[0068] Add 6mol of pancreatic lipase (the amount of pancreatic lipase added is 60mmol / Kg) to 100Kg of separated plasma liquid, enzymolyze at 35°C for 15min, and then add 12mol of neutral protea...

Abstract

The invention discloses soluble plasma protein powder and a preparation method thereof. The soluble plasma protein powder is a mixture prepared by uniformly mixing milk powder and plasma protein powder, wherein the milk powder accounts for 10-40% of the total mass of the soluble plasma protein, pig blood accounts for 40-84% of the total mass of the plasma protein powder, and sugar accounts for 6-20% of the total mass of the plasma protein powder; the plasma protein powder is rich in fragrance, free of blood fishy smell and good in solubility and brewing stability. The preparation method comprises the preparation and operation steps of vacuum blood collection, blood anticoagulation, step-by-step enzymolysis deodorization, membrane concentration, addition of ingredients, high-pressure homogenization, spray drying, and baking and aroma extraction. The soluble plasma protein powder is fragrant, sweet and mellow in taste, has strong milk fragrance and uniform particles, and is easy to dissolve and free of caking and bad fishy smell after being brewed. The whole set of technology is adopted to process the pig blood into the convenient and instant plasma protein powder, so that the development and utilization of blood resources are realized, the utilization value of by-products such as the pig blood is greatly improved, and the market vacancy of the food plasma protein in China is supplemented.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for preparing blood plasma protein powder. Background technique [0002] my country is the world's largest producer of pigs, and more than 2.6 million tons of blood are produced every year due to pig slaughtering. If this rich animal blood resource is thrown away as waste, it will not only cause a great waste of resources, but also bring great pollution to rivers and groundwater. Therefore, the development and utilization of animal plasma protein powder products can not only solve the problem of environmental pollution, but also realize the development and utilization of blood resources in my country, greatly enhance the utilization value of pig blood and other by-products, and supplement the market vacancy of my country's food plasma protein. major. [0003] At present, domestic development and utilization of plasma protein powder is limited to simp...
