Monosodium glutamate (MSG) is the sodium salt of the common amino acid glutamic acid. The below diagram is the flowchart showing the preparation of MSG. MSG occurs naturally in many foods, such as tomatoes and cheeses. People around the world have eaten glutamate-rich foods throughout history. As the flowchart illustrates, instead of extracting and crystallizing MSG from seaweed broth, MSG is produced by the fermentation of starch, sugar beets, sugar cane, or molasses. This fermentation process is similar to making yogurt, vinegar, and wine. Use EdrawMax Online to create a similar-looking flowchart depicting the preparation of MSG.
