| titleOfInvention | Method for extracting high-purity collagen from bovine bone |
| abstract | The invention relates to the technical field of biological collagen preparation, in particular to a method for extracting high-purity collagen from bovine bone, which comprises the following steps: s1, cleaning fresh ox bones; s2, putting the cleaned ox bone into a reactor, adding an ethanol solution, ventilating, sealing and reacting to prepare ox bone slurry; s3, processing the bovine bone slurry by using a high-pressure homogenizer to form uniform bovine bone slurry; s4, adding an acid solution into the ox bone slurry, uniformly mixing, performing ultrahigh pressure impinging stream treatment and closed reaction kettle treatment, performing high-voltage pulse electric field treatment, performing closed reaction kettle treatment, and performing solid-liquid separation by using a filter press to obtain an extracting solution; s4, performing ultrafiltration treatment on the extracting solution, collecting ultrafiltrate, and performing spray drying to obtain collagen; the purity of the collagen of the invention is more than 98 percent, the yield of the collagen is more than 90 percent, the bioactivity of the collagen is improved, the absorption and utilization rate of a human body is improved to more than 98.5 percent, and the extraction time is short. |
