monosodium glutamate was invented in Japan. The first inventor of monosodium glutamate was researcher Ikeda Jumiao from Imperial University of Tokyo, Japan. He was a chemist and held the post of professor at Imperial University of Tokyo.
monosodium glutamate was invented because he drank the cucumber soup made by his wife. In the exceptionally delicious cucumber soup, his wife added kelp, 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 the feeling of umami. Later, he called this substance monosodium glutamate, and applied for a patent to establish "flavor essence".
Selection:
When purchasing monosodium glutamate, the trademark and manufacturer should be identified first. Pay attention to the marked sodium content of glutamine and whether the packaging and sealing are complete. If the packaging and printing are rough and the sealing is not standardized, you should not buy it. 99% monosodium glutamate is granular crystal, white and bright; 8% or 9% monosodium glutamate is powdery and white in color. Take a few tablets and put them on the tip of your tongue. They are cold and delicious, so they are good monosodium glutamate. If it smells fishy, insoluble or salty, sweet and bitter, it is adulterated monosodium glutamate.
