Abstract Large amounts of by-products and wastes are generated during animal processing. These products are rich in biologically active proteins, which can be converted chemically or enzymatically into collagen peptides with special physiological functions. Collagen has nutritional value and is difficult to digest and absorb by the body due to its high molecular mass. Collagen peptides have a small molecular mass and are more easily digested and absorbed by the human body, which have been reported to show various special physiological functions and thus have become one of the research hotspots in recent years. The advantages and disadvantages of the methods to prepare collagen peptides derived from animal by-products are reviewed, the digestion and absorption characteristics of collagen peptides in the human body are briefly described, and the application of collagen peptides in food processing is also summarized. We expect that this review will provides a new idea for the future development of new collagen peptide products.
