I don't really think it would be too difficult to pen the letter. The info is in this thread. I think my first post in here would pretty much suffice as to info needed. I guess it's simply a case of asking them directly whether the hydrolysation process they use creates free glutamate as per all other hydrolysation processes.

Is there a PeptoPro amino breakdown? If not, that would be good to get; they will show the glutamate %. If they don;t show you'll know why

What is PeptoPro®?
PeptoPro® is a protein hydrolysate derived from the casein protein fraction of cow’s milk. It consists of ~85% protein. The protein is rich in small peptides; ~60% is smaller than 500 Dalton. Molecular mapping indicates that ~7.5% is free amino acids, ~8.5% is dipeptides, and ~39% is tripeptides.

How is PeptoPro® produced?
PeptoPro® is produced by enzymatic hydrolysis of sodium caseinate. Two food-grade enzymes are used of which one is exclusively developed to reduce bitterness. After hydrolysis, the solution is heat treated such that all enzymes are irreversibly inactivated. The solution is then concentrated and spray dried. All processing conditions are controlled in order to accommodate optimal enzyme action and to prevent bacterial contamination and outgrowth during the process.

It has been shown that WPI is better than Hydro Whey in getting BCAA into your blood

whethere its peptopro, isolate, eaa, bcaa, goats milk, or teradactyl man juice - the wider diet is key not what you take at a given time.

PeptoPro is produced using a couple of different enzymes which have been specially developed to cut the amino acid chains into di and tri peptides. There is no significant cleaving from the ends of the chains, so there is only a small percentage of free amino acids in the product. PeptoPro consists of ~60% di and tri peptides, but less than 6% free amino acids, which is much lower than most hydrolysed proteins.

You can take further comfort in the fact that PeptoPro comes from DSM, which is the world's largest supplier of nutritional ingredients like vitamins, carotenoids, enzymes and other fine chemicals. We always ensure we supply high quality, effective and safe ingredients.
