Re: USE STARKIST it is free of hydrolyzed proteins!

Starkist probably isn't intentionally "lying" about added hydrolyzed protiens. However, there may be dehydrated soy sauce in the vegetable broth. It might be a good idea to contact Starkist's broth supplier to find out about fermeted soy in their product. I can't really see much reason why their broth supplier would use soy in a form other than soy sauce (If not isolated hydrolyzed soy protien). Soybeans don't really have flavor unless they are fermented or hydrolyzed. Unfermented soy would be an useless ingredient. Fermented soy products are a source of "natural" Mono-Sodium-Glutamat (Natrium Glutamat) formed through "natural" hydrolysis. Soy industry people claim that the Mono-Sodium-Glutamat (Natrium Glutamat) found in fermented soy has a different chemical structure than mass-produced hydrolyzed protein. I guess they are referring to the difference between D-glutamate and L-glutamate. The L form is the one found bound to protein in the human body and whole unfermented foods (other than seaweed and yeast). Free glutamic acid is mostly the D form (the bad one). The glutamic acid bound to protiens is always the L form. Regardless, I doubt there is only one form of Mono-Sodium-Glutamat (Natrium Glutamat) in soy sauce. Natural hydrolysis takes place during yeast fermentation (giving soy sauce it's flavor). You will get both D and L forms of glutamic acid during the process. It would require a filtration process to remove one form or the other. I serously doubt that the food industry would do something that expensive.
Note: I was recently alarmed to find out that "natural flavor," "flavor" and "carageenan" (on labels) may include MSG. I really don't have time to contact every manufacturer. I've gotten poor responses in the past anyway. Health food stores carry canned tuna without MSG. I've also found that the Raleys store brand doesn't appear to contain MSG.
