Hydrolyzed protein

Hydrolyzed Protein is protein that has been hydrolyzed or broken down into its component amino acids. While there are many means of achieving this, two of the most common are prolonged boiling in a strong acid or strong base or using an enzyme such as the pancreatic protease enzyme to stimulate the naturally-occurring hydrolytic process.

According to the FDA, hydrolyzed protein is used to enhance flavor and contains monosodium glutamate. When added this way, the labels are not required to list MSG as an ingredient. .
