Product Usage

L-glutamic acid or its salt, monosodium glutamate (MSG), is used as an additive to human food to enhance the taste. Although seaweed had been used in Asia to enhance food flavor for over 1000 years, it was not until 1908 that the essential component responsible for the flavor phenomenon was identified as glutamic acid.
