It is commonly used in conjunction with glutamic acid (monosodium glutamate, MSG).s it is a fairly expensive additive, it is not used independently of glutamic acid; if disodium guanylate is present in a list of ingredients but MSG does not appear to be, it is likely that glutamic acid is provided as part of another ingredient such as a processed soy protein complex.
