At the same time, the umami taste of sodium glutamate can only be presented in the presence of salt, and it has a certain inhibitory effect on sour taste and bitter taste, that is, it has a certain degree of taste buffering effect. If you add pure monosodium glutamate to dishes without salt, it will not only have no umami flavor, but will make people feel an unpleasant smell.
