The invention relates to a collagen peptide for intestinal absorption and an extraction method and application thereof. The method comprises the following steps: firstly, the skin of giant salamander is cleaned and deodorized, and then it is soaked in NaOH solution After enzymolysis, the treated giant salamander skin is enzymatically hydrolyzed, then subjected to enzymatic inactivation treatment, and then centrifuged and filtered to collect the filter residue; the filter residue is subjected to microfiltration, ultrafiltration and sodium filtration in turn, and then concentrated, then freeze-dried and pulverized , to obtain collagen peptides for intestinal absorption. The method for extracting collagen peptides for intestinal absorption of the present invention reduces the production cost, and the collagen peptides extracted by the method of the present invention can supplement the collagen lost due to skin collapse, relaxation, wrinkles and other aging problems at the same time. , Repair and regenerate its own collagen, natural and non-stimulating, with good free radical scavenging effect, can be used as a daily skin care product to prevent aging, and the anti-aging effect is very obvious. |
