What is Hydrolyzed Soy Protein?
Hydrolyzed soy protein is soy protein that has gone under the process of hydrolysis. 
The extraction process of hydrolysis involves boiling in a vat of acid (e.g., sulfuric acid) and then neutralizing the solution with a caustic soda. The resultant sludge is scraped off the top and allowed to dry. In addition to soy protein it contains free-form excitotoxic amino acids (e.g., MSG) and other potentially harmful chemicals including cancer-causing chemicals in many cases. A newer method of hydrolysis involves the use of bacteria by itself or in addition to the chemical processes described above. There is a possibility that genetically-manipulated bacteria may be used.
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.
