(57) [PROBLEMS] To provide a collagen peptide derived from fish that can be suitably used for food and drink, cosmetics, etc., has no fish-specific taste and odor, has excellent safety, and a method for producing the same, and further includes the collagen peptide. Provide food and drink and cosmetics to contain. A free amino acid content in a solid content is prepared by preparing an extract containing collagen from fish skin and / or fish bones, enzymatically degrading the extract, concentrating and purifying using a reverse osmosis membrane. 1.0% by mass or less, arsenic content is 2pp The collagen peptide derived from fish which is m or less is obtained, and this is mix | blended with food-drinks and cosmetics. The average molecular weight of the collagen peptide is preferably 1,000 to 10,000. Moreover, it is preferable to include the process of decoloring and deodorizing the extract containing the said collagen, or its enzyme decomposition product. Furthermore, it is preferable to use a reverse osmosis membrane having a salt rejection of 10 to 50%. |
