Hydrolysis frees more than just glutamate. Your stomach acid hyrolyzes proteins, and works alongside proteolytic enzymes. Pre-hydrolyzed whey protein could be thought of as being predigested. The free aminos (all of them) would enter the blood more rapidly than from whey protein concentrate. There would be a collective effect of multiple amino acids, all dependent on the rate of uptake, which would relate to degree of hydrolysis, dose, combination with other foods, genetic factors, etc.
The simplest factor to manipulate is dose. There's a simple test if free glutamate is the issue.....add in some taurine with the whey protein. If the adverse effects are eliminated, you can consider glutamate, or it could be an adaptive response from repeated exposure.
Why might never be known, but dose is easily tested.
