| titleOfInvention | Method for extracting and preparing swimming bladder collagen oligopeptide |
| abstract | An extraction and preparation method of swimming bladder collagen oligopeptide comprises the following specific steps: cleaning: selecting swim bladders, cleaning, crushing into small pieces, adding a sodium hydroxide solution for soaking, soaking by using a 5-10% n-butyl alcohol or isopropanol solution after water washing to be neutral, and homogenizing after water washing to be neutral for later use; pretreatment: adding tannic acid into the homogenate, filtering, adding protease in alkaline environment for enzymolysis, and passing through a resin column; enzymolysis: adjusting the pH value, and adding 0.1-1.0% of compound protease for enzymolysis; and (3) purification: the method comprises the following steps: membrane filtration, nanofiltration, concentration, sterilization and spray drying. The scheme effectively removes the fishy smell, has simple extraction process, and has high yield and good quality of the swimming bladder collagen oligopeptide. |
