Description
Technical field
The invention belongs to fresh donkey blood processing technique field, be specifically related to a kind of low ash content donkey SDPP and preparation method thereof.
Background technology
China's forage yield occupies the second in the world, but mostly is low-end product, and animal blood is the protein sources of high-quality, in current livestock and poultry cultivation, and the rotten waste of most blood, and cause environmental pollution.Therefore, high-quality animal blood feed, promotes feed industrial upgrading.Along with being on the increase of China's raising pets amount, it is high-quality that people also pursue high protein to the feed of pet, SDPP mostly is the manufacture of pig blood now, application number is the preparation method that 201010525103.1 Chinese patent discloses a kind of low-ash pig plasma protein powder, be take pig after butchering discarded object---pig blood is raw material, adopt centrifugation, ultrafiltration concentration and spray drying technology to make a kind of novel SDPP.The SDPP content of ashes obtaining is low, and TVB-N content is low, and immunoglobulin content is high, and digestibility is high, dissolubility is good, and good palatability is safe, balanced in nutrition, short weanling pig growth result is obvious, can be used as the supplementary source of feed protein.
And donkey blood moistens enteron aisle, the effect of the ventilation of invigorating blood circulation is that industry is known, and nowadays the donkey number of animals raised constantly increases, and except medicinal, residue donkey blood is no lack of rotten waste.
Summary of the invention
First technical problem that the present invention will solve is to provide a kind of low ash content donkey SDPP, and this albumen powder is under the prerequisite of kill virus and bacterium, has kept to greatest extent the nutritional labeling in donkey blood, is a kind of novel high-quality SDPP.
Second technical problem that the present invention will solve is to provide a kind of preparation method of low ash content donkey SDPP, from raw material, enters into finished product, all in the closed conduct after sterilization, completes, and avoided the pollution in process.
For solving first technical problem, the present invention adopts following technical proposals:
A low ash content donkey SDPP, described low ash content donkey SDPP is canescence, powdery, free from extraneous odour, its content of ashes≤5%, crude protein >=83%, immunoglobulin (Ig) >=22%, solubility >=96%, VBN <260mg/kg; Salinity≤3.5, coarse ash≤11.0, moisture≤9.0, lysine >=3.5%, crude fibre≤3.0, total phosphorus 0.15～0.5; Virus does not all detect.
For solving second technical problem, the present invention adopts following technical proposals:
A preparation method for low ash content donkey SDPP, comprises following preparation process:
(1) anti-coagulants and anti-hemolytic agent are added in fresh donkey blood and mixed, be placed in 4-6 ℃ of blood refrigerating case;
(2) utilize the separated thickener of high accuracy cartridge type blood by the blood cell of above-mentioned fresh donkey blood and plasma separation, concentrated; Wherein, the separated thickener of GFXB105 type blood that the separated thickener of high accuracy cartridge type blood is Liaoyang sunlight pharmaceutical machine Co., Ltd;
(3) above-mentioned concentrated blood plasma is inserted in 4～6 ℃ of storage tanks;
(4) the plasma protein removal of impurities ash disposal subset that the model of employing Chengdu He Cheng filtering technique Co., Ltd is HC-Z-50, carries out de-ash and desalting processing by blood plasma;
(5) use high-pressure fog sterilizer to carry out bacteria inactivation rate; Press spraying sterilizer to adopt the high-pressure spray-drying tower that the model of Changzhou southeast drying equipment Co., Ltd is LPG;
(6) adopt sterile packaging machine packing, get product and be placed in 16 ℃～18 ℃ ambient storage.
Preferably, the described anti-coagulants of step (1) is that concentration is 0.3%～1% natrium citricum, and preferably the concentration of natrium citricum is 0.7%～1%; Described anti-hemolytic agent is that concentration is 2.5%～5% sodium chloride, and preferably, sodium chloride concentration is 4%～5%.
