Abstract
The invention belongs to field of biotechnology, more particularly to a kind of collagen peptide complexes and preparation method thereof, the collagen peptide complexes, including inner core and the shell for being wrapped in inner core outer layer, the main component of the inner core is anthocyanin and collagen peptide, and the main component of the shell is collagen peptide.The present invention utilizes the stability and easy absorbability of collagen peptide; anthocyanin is protected using collagen peptide as shell; both collagen peptide and anthocyanin multiple health care may be implemented; the stability of anthocyanin can be greatly improved again; the degradation of anthocyanin, promotes human body that anthocyanin is absorbed and utilized under the conditions of reduction illumination, oxygen etc..
Description
Technical field
The invention belongs to field of biotechnology more particularly to a kind of collagen peptide complexes and preparation method thereof.
Background technique
Collagen peptide is a kind of extracellular protein, and molecular weight is mostly 0.5kDa-20kDa or so, with collagen phase
Than collagen polypeptide not only has the nutritive peculiarity of collagen, but also can be by human body active and accessible absorption, without disappearing
Change, made full use of for bodily tissue, there is the advantages that absorption easy to digest, hypoallergenic, edible safety.In addition, collagen
Polypeptide also has anti-oxidant, blood pressure lowering, improves immunity, improves memory and the bioactivity such as antitumor.Currently, depositing on the market
In miscellaneous collagen peptide health-care products, however due to formula in component it is single, it is difficult to realize multi-component health-care effect, nothing
Method meets the needs of people.
Anthocyanin is a kind of compound that anthocyanidin and sugar are combined into glycosidic bond, is widely present in flower, the fruit of plant
