Salt And Yeast Extract

Salt and yeast extract is a combination of two common food ingredients. Yeast extract is made by breaking down yeast cells, often from *Saccharomyces cerevisiae*, and concentrating their natural contents, which are rich in amino acids. Salt (sodium chloride) is then added to this concentrated yeast material.

Manufacturers add salt and yeast extract primarily to enhance the savory (umami) flavor of foods. It is commonly found in seasoning mixes, sauces, broths, and various processed foods to provide a rich, meaty taste. The salt also acts as a basic seasoning and a mild preservative.

Both yeast extract and salt are generally recognized as safe (GRAS) by the FDA for use in food. Yeast extract naturally contains glutamates, which contribute to its savory flavor, similar to how MSG provides umami. JECFA has evaluated yeast extract and determined that an acceptable daily intake (ADI) does not need to be specified. For salt, the FDA Daily Value is 2,300 mg, and JECFA has also evaluated sodium chloride. While yeast extract is not MSG, some individuals may confuse the two due to their shared glutamate content; however, yeast extract contains naturally occurring glutamates as part of a complex mixture, unlike purified MSG.
