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 industry upgrading.Along with being on the increase of China's raising pets amount, people also pursue high protein high-quality to the feed of pet, SDPP mostly is the manufacture of pig blood now, application number be 201010525103.1 Chinese patent disclose a kind of preparation method of low-ash Swine plasma protein, the discarded object after butchering with pig---pig blood is raw material, adopts centrifugation, ultrafiltration concentration and spray drying technology to obtain a kind of novel SDPP.The SDPP content of ashes obtained is low, and TVB-N content is low, and immunoglobulin content is high, and digestibility is high, dissolubility is good, good palatability, and security is high, balanced in nutrition, short weanling pig growth result is obvious, can as the supplementary source of feed protein.
And donkey blood moistens enteron aisle, the effect of 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 that maintaining the nutritional labeling in donkey blood to greatest extent, is a kind of SDPP of novel high-quality under the prerequisite of kill virus and bacterium.
Second technical problem that the present invention will solve is to provide a kind of preparation method of low ash content donkey SDPP, enters into finished product, all completes in the closed conduct after sterilization, avoid the pollution in process from raw material.
For solving first technical problem, the present invention adopts following technical proposals:
A kind of 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 mix, be placed in 4-6 DEG C of blood refrigerating case;
(2) utilize high accuracy cartridge type blood to be separated thickener the blood cell of above-mentioned fresh donkey blood to be separated with blood plasma, to concentrate; Wherein, high accuracy cartridge type blood is separated the GFXB105 type blood separation thickener that thickener is Liaoyang sunlight pharmaceutical machine Co., Ltd;
(3) above-mentioned concentrated blood plasma is inserted in 4 ~ 6 DEG C of storage tanks;
(4) adopt the model of Chengdu and sincere filtering technique Co., Ltd be the plasma protein removal of impurities of HC-Z-50 except ash tool, blood plasma is carried out de-ash and desalting processing;
(5) high-pressure fog sterilizer is used to carry out bacteria inactivation rate; The model of pressure spraying sterilizer employing Changzhou southeast drying equipment Co., Ltd is the high-pressure spray-drying tower of LPG;
(6) adopt sterile packaging machine packaging, get product and be placed in 16 DEG C ~ 18 DEG C ambient storage.
Preferably, step (1) described anti-coagulants to be concentration be 0.3% ~ 1% natrium citricum, preferably the concentration of natrium citricum is 0.7% ~ 1%; Described anti-hemolytic agent to be concentration be 2.5% ~ 5% sodium chloride, preferably, sodium chloride concentration is 4% ~ 5%.
Preferably, the centrifugal force of the described separation thickener of step (2) is 5000g ~ l00000g.
Preferably, in step (4) de-ash and desalting processing, desalination temperature is 18 ~ 22 DEG C, and blood plasma pH is 8.
Preferably, step (5) spray drying step spray drying tower used is vertical tower, atomizing type is the one in centrifugal, pressure type or pneumatic dryer, drier EAT is 250 DEG C ~ 350 DEG C, leaving air temp is 80 ~ 90 DEG C DEG C, maximum water evaporation quantity is lkg/h ~ lOkg/h, is preferably 5kg/h ~ lOkg/h; Atomizing disk maximum (top) speed is lOOOr/min ~ 40000r/min.
Beneficial effect of the present invention:
1, traditional drying process is boiling and drying, its shortcoming is the aforesaid nutrition greatly reducing SDPP, the present invention adopts spray drying step, spraying dry can rapid draing raw material, little to the fire damage of albumen, and the pollution of process can be reduced, and multiple virus and bacterium can be killed.Spraying dry of the present invention has selected specific process conditions: spray drying tower used is vertical tower, and atomizing type is the one in centrifugal, pressure type and pneumatic dryer.The donkey SDPP prepared thus obtains excellent combination property.
2, the high-purity separation machine that the technical program adopts achieves blood cell and is totally separated thoroughly with blood plasma, ensure that the organoleptic quality of blood plasma.The ultrafiltration recycle unit that the technical program adopts, through most salinity and moisture, can retain the albumen of more than little peptide, serve the object of concentrating and desalinating, greatly reduce ash content and the moisture of finished product, improve protein content, and the effect reducing energy consumption can be played.The spray drying technology that the technical program adopts, the mist droplet that its high rotating speed is formed ensure that abundant drying, finished product uniformity; High accuracy ensure that material purity, free from admixture; Baking temperature controls the activity of the immunoglobulin (Ig) that ensure that in product; The TRANSIENT HIGH TEMPERATURE formed can kill presumable pathogenic microorganism and virus in raw material, ensure that the biological safety of product.In whole process, produce and complete in the pipeline closed, each link is strictly separated, and avoids secondary pollution.
