Hydrolyzed proteins, you’ll find them in processed foods, pet food, “nutrition” shake mixes and even baby food.
But if you had any question about the excitotoxic (brain damaging) glutamate and aspartate content in hydrolyzed proteins, a recent research report Characterization of umami compounds in bone meal hydrolysate should set the record straight.
According to the report, “The free amino acids and peptides in the bone meal hydrolysate were analyzed. The results showed that the glutamic acid and the aspartic acid in the bone meal increased by 13.1 times and 14.2 times, respectively, after the Flavourzyme hydrolysis….The findings of this study demonstrated that the MSG‐like taste of the bone meal hydrolysate should be attributed to the generation of MSG‐like amino acids and peptides from the Flavourzyme hydrolysis.”
(Flavourzyme is a brand name for an enzymatic hydrolysis product that is used for protein extraction. This includes feather protein hydrolysis used for pet food, which the company says will allow processors to “turn feathers into profit.”)
The take-away is that the process of hydrolysis will invariably produce toxic glutamate, be it in bone meal, milk, corn or any other item that contains protein – including feathers.
