example 1

[0023] A low-ash plasma protein powder, the raw material is fresh healthy pig whole blood from the slaughterhouse, anticoagulant sodium citrate, sodium chloride is added to prevent hemolysis, refrigerated and sealed for transportation, sieved and then centrifuged, centrifugal force 80000g, centrifugation time 3min After separation, the plasma was refrigerated at 4°C to 6°C. The ultrafiltration concentration and desalination temperature is 20°C, the pH of the feed liquid is 8, the ultrafiltration pressure is 0.12MPa, the cycle ultrafiltration time is 40min, and the feeding volume is 2000L. The air inlet temperature of the spray drying tower is 230°C, and the outlet air temperature is 90°C. The prepared plasma protein is off-white amorphous powder, uniform, free of sundries, free of spoilage smell, its ash content is 5.7%, moisture is 6.2%, crude protein is 80.7%, immunoglobulin is 18.3%, solubility ≥ 96 %, volatile basic nitrogen <250mg / kg, Salmonella, swine fever virus, foot-...

Abstract

The invention relates to a plasma protein concentrating and drying technology, in particular to a method for preparing pig plasma protein powder with low ash content. In the invention, waste, namely pig blood left after pigs are killed is used as a raw material, and novel plasma protein powder is prepared by centrifugal separation, ultrafiltration concentration and spray drying technologies. The plasma protein powder prepared by using the method has low ash content, low volatile basic nitrogen content, high immune globulin content, high digestion rate, good solubility, good palatability, highsafety, balance nutrients and remarkable effects for promoting weaned pigs to grow, and can be used as a supplement source of feed protein. Through the effective utilization on the pig blood, not only the waste is turned into a valuable thing and benefits are brought to the society, but also the environments can be protected and the current green development tendency is met.

Description

technical field [0001] The invention relates to a plasma protein concentration and drying technology, in particular to a preparation method of low ash plasma protein powder. Background technique [0002] There is a large gap between the supply and demand of protein feed in my country every year. At the same time, the blood produced by slaughtering livestock and poultry in my country reaches 2.6 million tons every year, which can be made into more than 500,000 tons of pure blood powder. Most of this rich animal blood resource is thrown away as waste. It not only causes a serious waste of resources, but also causes environmental pollution of rivers and groundwater ammonia nitrogen. Therefore, it is of great significance to develop animal plasma protein powder, which can not only solve the problem of environmental pollution, but also increase the source and output of protein feed, and can generate huge economic benefits. [0003] The production process of spray-dried plasma ...
