Hi
glutamic acid hydrochloride can be used as a preservative as well as
another food ingredient. If used as a preservative it also can be found
under the name glocono delta lactone,which also acts like a slow rising
agent in baked goods if you cannot use yeasts.Basically you could say that
GDL or glutamic acid hydrochloride is one of the fruit acids. Glucono delta
lactone is glutenfree. I am digging up the other use for glutamic acid
hydrochloride.This should be most likely also 100% glutenfree.I will send
the info as soon as possible.
