The first person who invented monosodium glutamate was Ikeda Miaoju, a researcher at Imperial University in Tokyo, Japan. He is a chemist and a professor at Imperial University in Tokyo. He invented monosodium glutamate because he drank his wife's cucumber soup, and her wife added kelp to the exceptionally delicious cucumber soup, so he thought that the secret of making the soup delicious was kelp.
Sure enough, there is something called sodium glutamate in kelp, which can produce a delicious feeling. Later, he called this substance monosodium glutamate, and applied for a patent to establish a flavor element. In fact, monosodium glutamate not only contains sodium glutamate, but also contains salt, which effectively improves the umami taste of food.
