Abstract
Collagen peptide compositions and methods for producing these collagen peptide compositions from fish skin or fish scale are provided. The collagen peptide compositions are characterized by high protein content, minimal impurities, enriched hydroxyproline, and specific peptide sequences, making them suitable for use as supplements or additives in food and beverages.
Claims22
A collagen peptide composition comprising collagen proteins having an average molecular weight of less than 2000 Da and having a protein content of at least 90 wt % based on the total weight of the composition,
- wherein per 100 g of the collagen proteins comprises 7 to 10 g of hydroxyproline amino acids, 10 to 25 g of dipeptides and 15 to 25 g of tripeptides.
A method for producing a collagen peptide composition from fish skin, comprising:
- pretreating the fish skin with water at a temperature ranging from 30 to less than 60° C. for 10 to 30 minutes;
- extracting a crude collagen from the pretreated fish skin using a heated water of 60 to 90° C. for 1 to 5 hours;
- hydrolyzing the crude collagen by at least one protease enzyme;
- and
- isolating collagen peptides from the hydrolyzed collagen to provide the collagen peptide composition, the collagen peptide composition comprising collagen proteins having an average molecular weight of less than 2000 Da and having a protein content of at least 90 wt % based on the total weight of the composition, wherein per 100 g of the collagen proteins comprises 7 to 10 g of hydroxyproline amino acids, 10 to 25 g of dipeptides and 15 to 25 g of tripeptides.
A method for producing a collagen peptide composition from fish scale, comprising:
- extracting a crude collagen from the fish scale using a heated water of 80 to 100° C. for 4 to 8 hours;
- hydrolyzing the crude collagen by at least one protease enzyme;
- and
- isolating collagen peptides from the hydrolyzed collagen to provide the collagen peptide composition, the collagen peptide composition comprising collagen proteins having an average molecular weight of less than 2000 Da and having a protein content of at least 90 wt % based on the total weight of the composition, wherein per 100 g of the collagen proteins comprises 7 to 10 g of hydroxyproline amino acids, 10 to 25 g of dipeptides and 15 to 25 g of tripeptides.
