Abstract:

BACKGROUND: Collagen peptide, the peptide mixtures formed by the disassembly and breakage of molecular chains of collagen, is applied widely across domains including biomedicine, cosmetics and food thanks to its characteristics of low molecular weight, excellent biocompatibility, and good absorptivity.

OBJECTIVE: To introduce the structural characteristics, classification and sources of collagen and collagen peptides, focus upon the preparation and bioactivity of collagen peptide and the evaluation of transdermal absorption. We prospected the future to obtain quality collagen peptide material from aquatic animal and to apply it to domains with high added value including biomedicine and cosmetics.

METHODS: We searched the articles published from January 1997 to June 2020 in PubMed, CNKI, and Wanfang databases about the preparation and examination of collagen peptide and the methods of evaluating transdermal absorption with the keywords including “collagen, collagen peptide, transdermal absorption, preparation of collagen peptide, collagen peptide detection” in Chinese and English respectively. 
RESULTS AND CONCLUSION: Studies into evaluation methods of the transdermal absorption of collagen peptides remain to be few in numbers, though there has been a lot about the preparation of collagen peptides. The existing studies upon the evaluation methods are majorly based upon those into the transdermal penetration of drugs. In the context where the collagen peptide industry in China remains to be immature, full attention should be paid to the actual effect and the products should be refined with the more specifically classified functions in the progress of product research and development.
