How is MSG made?

In the early 1900s, MSG was extracted from natural protein-rich foods such as seaweed. Today, MSG is made from starch, corn sugar or molasses from sugar cane or sugar beets. MSG is produced by a natural fermentation process that has been used for centuries to make such common foods as beer, vinegar and yogurt.
