| titleOfInvention | Method for producing oxhide gelatin by using pickled raw skin |
| abstract | The invention belongs to the technical field of gelatin extraction, and particularly relates to a method for producing oxhide gelatin by using pickled raw skins. The method is realized by the following steps: removing hair from cow leather, cleaning, and degreasing; stirring and soaking the degreased cowhide in a gradient sodium chloride-triethanolamine aqueous solution, and filtering and cleaning the cowhide after soaking; adding the treated cow leather into a phosphate buffer solution containing sodium dodecyl sulfate, adding acid protease and dioctyl sodium sulfosuccinate for enzymolysis, and performing enzyme passivation after the enzymolysis is finished; cleaning the cow leather after enzymolysis to be neutral, oscillating sol, filtering to obtain glue solution, centrifuging the glue solution, collecting supernatant, and freeze-drying. The extraction method provided by the invention can improve the extraction rate of the gelatin, and the extracted gelatin has high purity, meets the relevant standards of medicinal oxhide gelatin and has uniform granularity; the method provided by the invention can shorten the enzymolysis time without influencing the gelatin yield. |
