peptidhydrolys

Peptidhydrolys, also known as peptide hydrolysate, is a product containing a mixture of short peptides and free amino acids produced by the hydrolysis of proteins. It is created by breaking peptide bonds in proteins through enzymatic action using proteases, or by acid or alkaline hydrolysis. The degree of hydrolysis and the resulting peptide size distribution determine its functional properties and potential applications.

Manufacturing and composition are characterized by the presence of di-, tri-, and longer peptides along with free amino acids. In practice, peptide hydrolysates are often formulated to have a molecular weight cut-off below a few kilodaltons, which can influence solubility, taste, and digestibility. Enzymatic processes allow selective control over the hydrolysis to achieve desired nutritional and functional profiles.

Applications include food and beverage manufacturing, medical and clinical nutrition, infant formulas, and sports nutrition products. In medical contexts, hydrolysates are used to improve protein tolerance in individuals with digestive disorders, pancreatic insufficiency, or cow’s milk protein allergy, with products marketed as extensively hydrolyzed or amino acid-based formulas. In general nutrition, hydrolysates can enhance solubility and digestibility and are valued where rapid amino acid delivery is beneficial. Taste can be bitter due to the peptide mixture, which influences product formulation.

Safety and regulation emphasize accurate labeling of hydrolysate content, degree of hydrolysis, and potential allergenicity. Quality control typically assesses the degree of hydrolysis, peptide size distribution, free amino acid content, moisture, and microbial load to ensure consistency and safety.
