Solution derived from the hydrolysis of a protein into its component amino acids and peptides
Hydrolyzed protein is a solution derived from the hydrolysis of a protein into its component amino acids and peptides. While many means of achieving this process exist, the most common method is prolonged heating with hydrochloric acid,[1] sometimes with an enzyme such as pancreaticprotease to simulate the naturally occurring hydrolytic process.
Some hydrolyzed beef protein powders are used for specialized diets for athletes.[8]
Protein hydrolysis can be used to modify the allergenic properties of infant formula. Reducing the size of cow milk proteins in the formula makes it more suitable for consumption by babies suffering from milk protein intolerance. The US FDA has approved a label for this usage of partially-hydrolyzed proteins in 2017,[9] but a meta-analysis published the same year shows insufficient evidence for this use.[10]
Hydrolyzed protein is also used in certain specially formulated hypoallergenic pet foods, notably dog foods for dogs and puppies that suffer from allergies caused by certain protein types in standard commercial dog food brands. The protein contents of foods are split into peptides that reduce the likelihood of an animal's immune system recognizing an allergic threat. Hydrolyzed protein diets for cats are often recommended for felines with food allergies and certain types of digestive issues.[11]
