Is MSG a hydrolyzed protein

No, monosodium glutamate (MSG) is not a hydrolyzed protein. MSG is the sodium salt of glutamic acid, an amino acid, and is used as a flavor enhancer. Hydrolyzed proteins are created by breaking down proteins into smaller peptides and amino acids through a process called hydrolysis. While MSG can be derived from protein sources, it is a distinct compound and not a hydrolyzed protein itself.
