Sodium glutamate, with the CAS number 142-47-2, is a sodium salt of glutamic acid and is commonly known as monosodium glutamate (MSG). It is a white, crystalline powder that is odorless and has a taste characterized as umami, which is described as a savory or meaty flavor. This common food additive is used to enhance the flavor of dishes, especially in Asian cuisines .
Chemically, sodium glutamate is stable when exposed to light and heat. It begins to lose its crystalline water at around 120°C and melts at 232°C. The compound is highly soluble in water, with a solubility of about 71.7g per 100mL of water. It is slightly soluble in ethanol and practically insoluble in ether. In its solid state, it does not absorb moisture .
Sodium glutamate is produced industrially by fermenting sugar beet molasses, cane sugar, or starch derivatives with bacteria that convert the sugars into glutamic acid. The acid is then neutralized with sodium carbonate or sodium hydroxide to form the sodium salt .
In terms of applications, MSG is widely used in the food industry as a flavor enhancer. It is added to a variety of products, including savory snacks, soups, sauces, and seasonings to deepen their flavor profiles. It is also used in the pharmaceutical industry, primarily as a source of glutamate, which plays a role in metabolic processes in the body .
In storage, sodium glutamate should be kept in a cool, dry place, and away from light to maintain its quality. It is important to note that while it is considered safe for most people, individuals with certain health conditions or dietary restrictions may need to limit their intake or avoid it altogether
