The invention relates to a
collagen peptide used for
intestinal absorption, and an extraction method and application thereof. The method comprises the steps of firstly cleaning
andrias davidianus
skin, carrying out fishy smell
elimination treatment, then soaking the
andrias davidianus
skin in an NaOH solution, and washing the
andrias davidianus
skin with water; performing enzymolysis on the treated andrias davidianus skin, performing
enzyme deactivation treatment, performing
centrifugal filtration, and collecting filter residues; and sequentially carrying out
microfiltration,
ultrafiltration and
nanofiltration on the filter residues, and performing concentrating, freeze-
drying and smashing to obtain the
collagen peptide used for
intestinal absorption. According to the extraction method ofthe
collagen peptide used for
intestinal absorption, the production cost is reduced, the collagen
peptide extracted by adopting the method can repair and regenerate own collagen while supplementing collagen which is lost due to
aging problems such as skin collapse, looseness and wrinkles, and the collagen
peptide is natural and non-irritating, and has a good free radical
scavenging effect, can beused as a daily
skin care product for preventing aging, and has a very obvious anti-
aging effect.
