Sorbic Acid as a Food Preservative An Overview

In conclusion, E621, or monosodium glutamate, serves primarily as a flavor enhancer rather than a traditional preservative. While it enhances the taste of many processed foods, contributing to their palatability and potentially reducing food waste, it does not inhibit spoilage or extend shelf life in the same way traditional preservatives do. The safety of MSG has been affirmed by numerous health authorities, but ongoing discussions about food additives highlight the importance of consumer choice and transparency in labeling.
