| titleOfInvention | A kind of preparation method of sheep placenta transfer factor solution |
| abstract | The invention discloses a kind of preparation method of sheep placenta transfer factor solution, comprise the following steps: be the purified water of 2.5-3.5 by the Placenta caprae seu ovis processed and pH be 1 according to mass ratio: the ratio of (1-3) mixes, being placed in gap is that the colloid mill of 8-9 μm grinds to obtain homogenate, homogenate pH is regulated to be 2.5-3.5 with hydrochloric acid, grind again, obtain Placenta caprae seu ovis homogenate; Heat Placenta caprae seu ovis homogenate to 78-82 DEG C, temperature retention time >=10min, regulate Placenta caprae seu ovis homogenate pH to be 6.5-6.8 with NaOH after cooling, then centrifugal 30-45min under 4000-6000r/min, gets supernatant; With 6000 daltonian ultrafilter membranes, ultrafiltration is carried out to supernatant, obtain sheep placenta transfer factor solution.The inventive method is simple and convenient, directly can extract a large amount of transfer factors from Placenta caprae seu ovis, and can preserve at normal temperatures, to the time and money used and transport saving is a large amount of. |
