| titleOfInvention | Method for extracting collagen from cow leather |
| abstract | The invention relates to the technical field of collagen extraction, in particular to a method for extracting collagen from cow leather; the method comprises the following steps: (1) pretreating cow leather: soaking cowhide in complex enzyme solution A at constant temperature, draining, washing, and cutting into small pieces; putting the cowhide blocks into a protective solution for soaking treatment, draining, and drying in the air; (2) removing the hybrid protein: putting the cowhide blocks into a composite alkali solution for treatment, then putting the cowhide blocks into a micro-acid solution for soaking treatment, draining, washing and airing for later use; (3) preparing the cow hide pulp: mixing the cow hide blocks, ice water and a protective agent, and feeding the mixture into a high-speed refiner for homogenate to prepare cow hide pulp; (4) extracting collagen: adding complex enzyme B into the obtained cow hide pulp, stirring, extracting, and inactivating; performing solid-liquid separation to obtain an extracting solution for later use; (5) and (5) separating collagen. The extraction method provided by the invention has the advantages that the purity and the extraction rate of the collagen are high, and the collagen has good biological activity; and the process time is short. |
