Is msg the same as sodium benzoate?

No, monosodium glutamate (MSG) and sodium benzoate are not the same. MSG is a flavor enhancer commonly used in cooking, particularly in Asian cuisine, and is the sodium salt of glutamic acid. Sodium benzoate, on the other hand, is a preservative used to prevent the growth of bacteria, yeast, and fungi in acidic foods and beverages. While both are sodium salts, they serve different purposes in food processing.
