Hydrolyzed Soy Protein -- 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.
The food industry sometimes uses large amount of hydrolyzed proteins as a "taste enhancer" because it contains significant amounts of MSG (monosodium glutamate). This is what is known in the food industry as "Clean Labels" -- adding MSG to food, without having to list it as "MSG" on the label.
In almost all cases, hydrolyzed soy protein contains a significant amount of genetically-manipulated soy. The hydrolyzed protein products currently added to foods should be considered a detriment to one's health. There are much healthier sources of soy protein and soy nutrients.
