| titleOfInvention | Method for extracting undenatured natural collagen by ionic liquid pretreatment |
| abstract | The invention discloses a method for extracting undenatured natural collagen by ionic liquid pretreatment, which comprises the steps of immersing organism tissues containing natural collagen into ionic liquid with the mass concentration of 50-80%, stirring and reacting for 8-16 h at the temperature of 4-15 ℃, filtering out solid products and washing after the reaction time is up, and then centrifuging to obtain precipitates; extracting the undenatured natural collagen in the precipitate obtained by the centrifugal treatment to obtain an undenatured natural collagen solution. The invention improves the extraction rate of the undenatured natural collagen and shortens the extraction time by the pretreatment method. |
